WARNINGS
Only properly qualified personnel may work on or around this equipment.
The successful and safe operation of this equipment is dependent on proper handling, storage and installation. Correct functioning is also dependent on the use of SITOP
battery modules (e.g. battery modules of type 6EP1935-6MD11, 6EP1935-6MD31, 6EP1935-6ME21or 6EP1935-6MF01.
The charging current level and the end-of-charge voltage must be adjusted with DIP-switches to the settings recommended under "Technical Data". Setting incorrect
current and voltage values reduces the life of the battery and may cause irreparable battery damage.
CAUTION
Only trained personnel may open the unit. Electrostatically sensitive devices (ESD)
Disposal Guideline
Packaging and packing aids can be recycled and should always be disposed of for reuse.
The product itself shall not be disposed of as normal domestic waste.
Description and Design
The DC-UPS module 15 is a chassis unit in the SITOP power product range for mounting on a DIN rail of type DIN EN 50022-35x15/7.5.
The modules and the battery modules must be installed in accordance with the applicable DIN/VDE specifications or pertinent regulations in the country of installation (e.g. VDE 0510 Part2 / EN
50272-2).
In conjunction with the battery module, it buffers a proportion of the load current (max. 6A) of 24V load current supplies in the SITOP range.
Input "Input L+" on the DC-UPS module must be connected to output L+ of the 24V DC power supply unit and input "Input M" to output M of the power supply unit. The battery module is connected
to terminals +Bat and –Bat. The loads to be buffered are supplied via outputs "Output L+" and "Output M" on the DC-UPS module with the voltage connected to the input. If the 24V DC supply
voltage fails or drops below the set cut-in threshold, the battery module, which is maintained at full charge in continuous supply mode, is connected in to supply the loads.
The battery cut-in threshold, end-of-charge voltage, charging current and the buffering time can be set via DIP-switches. A switch is provided for setting a defined buffering (stored energy) time with
subsequent disconnection of the battery (see Settings).
The operating states of the DC-UPS module 6 are signaled by four LEDs, two floating changeover and one normally-open contacts and a serial interface (6EP1931-2EC31 only) or USB-interface
(6EP1931-2EC42 only) (see Signaling), the control signal “Remote Timerstart” and “Shutdown”.

Settings
Setting the cut-in threshold:
If the input voltage drops below the selected cut-in threshold voltage, the UPS module switches over to floating operation. The loads are then supplied solely by the battery module. The cut-in
threshold is set via three DIP-switches (see page 2 for position) according to table 2 (see page 7).
Setting range: 22.0 to 25.5V DC in 0.5-steps (delivery state: 22.5V DC ± 0.4V), accuracy ± 1.8%
Setting the charging current:
The battery module is charged at a constant current until the selected end-of-charge voltage is reached. The charging operation is then ended. When setting the charging current, please read the
instructions for the relevant battery module in order to select the optimum setting. The charging current is set by one DIP-switch (see page 2 for position).
Setting range: 0.35A DC ± 0.1A DC (ON) or 0.7A DC ± 0.1A DC (OFF) (delivery state: 0.7A DC ± 0.1A DC)
Setting the end-of-charge voltage:
The end-of-charge voltage depends on the battery type and on the battery`s ambient operating temperature. Table 1 (see page 7) shows the end-of-charge voltages for specific battery modules at
different temperatures. It is possible to interpolate between these values. The voltage is set by six DIP-switches (see page 2 for position) according to table 3 (see page 7).
Setting range: 26.3 to 29.2V DC in 0.1V-steps (delivery state: 26,6V DC ± 0.1V for +40°C lead-gel-battery temperature), accuracy ± 0.7%V DC
Note: for lower temperatures (recommended optimum temperature +20°C ... +25°C) increase the end-of-charge voltage according to table 1 !
Setting the operating state ON/OFF:

Caution: For normal operation "ON" state is necessary (delivery state is “OFF”), in order to achieve that use DIP-switch “ON” or terminal X2.9 connected with X2.10 !!
To prevent the battery from being discharged unintentionally (e.g. when the system power is disconnected), the DC-UPS module can be switched with a DIP-switch (or a wire jumper (or floating
connection) inserted between terminals X2.9 and X2.10) to operating state "OFF" (delivery state). In the "ON" state (DIP-switch closed or terminal X2.9 connected with a floating normally-open
contact (Vmax = 15V DC, Imax = 10mA) ), the DC-UPS module is fully functional according to specification. In the "OFF" state, the module does not switch over to floating operation when the mains
supply is disconnected but remains functional in every other respect. If the module is switched to "OFF" in floating operation, it stops operating in floating mode.
During normal operation, the polling interval for the ON/OFF setting is appr. 20s.
Setting the buffering time:
The buffering time is set via six DIP-switches (see page 2 for position) as illustrated in Table 4 (see page 7) in 10s-steps from 5s to 635s. By switch 1 (delivery state max. time) you can choose
whether floating operation will be terminated after a prespecified period or when the exhaustive discharge threshold of the battery (= maximum buffering time) is reached (delivery state: max.
buffering time). Using a 6EP1931-2EC31 or 6EP1931-2EC42 the remote signal starts the timer to terminate after a prespecified period. Once the battery has been disconnected, there is no way in
which floating operation can be restarted again by altering the switch setting. Only when the input voltage has recovered floating operation can be resumed. The buffering time is a minimum of 10
minutes until discharge to 20.4V DC with a charged battery module type 6EP1935-6MD11 (3.2Ah) and a load current of 5A. (requires a new battery modul with a temperature of the battery above
+20°C)
Interruption of the output voltage:
By a DIP-switch (see page 2 for position) you can choose if the output voltage is interrupted for 5 s at the end of the buffering time or not (delivery state : no interruption). In the case of 6EP19312EC31 and 6EP1931-2EC42 the output voltage is also interrupted via the remote signal of the interface.
Protective and Monitoring Functions
Reverse polarity protection: The UPS module is electronically protected against polarity reversal of the input voltage and battery.
Overcurrent and short-circuit protection: The UPS module is protected by an internal current limitation (typ. 25 to 40A for appr. 20 ms at a short-circuit,
1.05 to 1.4 IN for appr. 80ms at a overcurrent) in normal and floating operations. An internal 16A-fuse (not accessible) protects the module in case of failure. In normal operation automatic restart
attempts are made appr. every 20s. In floating operations the module shuts down in store mode. Restart after return to normal operation.
Exhaustive discharge protection:
Lead-acid batteries may only be discharged down to a certain voltage (exhaustive discharge threshold). Allowing them to discharge further will
reduce their service life and may result in irreparable battery damage. In order to protect the battery against damage, the UPS module is shut down in store mode and the loads disconnected from
the battery as soon as the battery voltage drops below typ. 19V DC (range 19.5 to 18.5V DC) in floating operation.
Battery test: In order to guarantee reliable floating operation, the battery module must be checked to ensure that it is fully functional. For this reason, the connected battery module is tested
every 4 hours under normal operation. The test is carried out only if the battery has not operated in floating mode or been disconnected within this 4 hour period. The battery test is not performed for
applications in which floating operation is activated regularly at shorter intervals. A defective battery is signaled by a flashing alarm and must be replaced then.

SITOP DC-USV-Modul 15
English
Signaling
"Normal operation", i.e. the input voltage at the DC-UPS module is higher than the set cut-in threshold. The loads are being supplied by the line-side power supply. If a battery module is
connected, it is fully charged. In normal operation, the green LED (o.k.) is illuminated and relay contact X2.2 – X2.3 (o.k.) is closed.
“>85% charge”, i.e. battery is loaded more than 85% (available rest capacity dependent upon aging). The second green LED (Bat>85%) is illuminated and relay contact X2.7 – X2.8 is closed. .
(second green LED off and relay contact X2.7 – X2.8 open (de-energized position when unit is disconnected) means : Bat<85%, i.e. battery charge below 85%)
"Floating operation", i.e. the input voltage is lower than the set cut-in threshold. The loads are being supplied by the battery module. In floating operation, the yellow LED (Bat) is illuminated
and relay contact X2.1 – X2.2 (Bat) closed (de-energized position when unit is disconnected).
Alarm signal "Battery not ready": When the "Battery not ready" signal is active, the red LED (Alarm) is illuminated and relay contact X2.4 – X2.5 (Alarm) closed (de-energized position when
unit is disconnected). Causes for the "battery not ready" state in normal operation are as follows: "OFF" operating state, no battery module connected, reversed polarity or defective battery (battery
voltage < 18.5V) or open circuit between battery and UPS module. The interval for polling the operating states ON/OFF, reversed polariy, defective battery or no battery module connected, open
circuit between battery and UPS module, and for activating the relevant signal output is 20 s during normal operation. After the end of the failure the signal remains till to the next polling.
If the signal flashes in a 2s cycle, this indicates that the battery is defective, but still capable of floating operation. The specified buffering times cannot be kept in such cases. The battery module
must be replaced.
The "Alarm" signal in floating operation means that the battery voltage has dropped to <20.4V and automatic disconnection to protect the battery is imminent. When the battery has been
disconnected due to overload, short circuit, exhaustive discharge protection or buffering timeout, the red LED (Alarm) goes out, but relay contact X2.4 – X2.5 remains closed. Load rating of relay
contacts: 60V DC / 1A or 30V AC / 1A
Interface: With module type 6EP1931-2EC31, the signals are additionally outputs via a PC-capable serial interface. They are each
displayed in the shape of 5 characters of plain text. The assignment is shown in the table on the right. When the battery is defective, the
signal "Battery ready / not ready" is displayed alternately in a 0.25Hz cycle with a duty cycle of 0.5. A tool for reading out and processing
the signals is available free of charge on the Internet at http://www.siemens.com/sitop-ups
. This website also contains further information about the interface.
Technical specification: 8N1 transmit and receiving, 9600 baud, 8 data bits, 1 stop bit, no parity bit, signal state output every 84ms ± 20%;
data output 29ms ± 20%, pause 55ms ± 20%.PC-interface has to be safety separated according to EN 60950. The connection to the PC is
made by means of a continuous 9-way SUB-D extension lead, (plug/socket), although only 3 pins are needed. (Pin2, Pin3, Pin7)
Transmit data: Pin2: RXD (data line, acc. to Pin3 of a 25-way plug/socket); Pin3: TDX (neg. supply for the interface, acc. to Pin2 of a 25-way
plug/socket); Pin7: RTS (pos. supply for the interface and at the same time data input line for the remote signal, acc. to Pin4 of a 25-way
plug/socket).
Receiving data: Pin7 (acc. to Pin4 of a 25-way plug/socket): Signal Remote Timerstart. Starts the timer in the DC-UPS module with the set
buffering time (table 2). After the set buffering time, floating operation ends or, during normal operation, the output voltage is interrupted for
5 s if "disconnection" is set. See diagram 1 (page 8) for the sequence of the necessary remote signal; this is generated by switching the
supply voltage of the interface in and off.

USB: With module type 6EP1931-2EC42, the signals are output additionally via a PC-capable USB interface. They are each displayed in the shape of 5 characters of plain text. The assignment is
shown in the table above. A tool for reading out and processing the signals is available free of charge on the Internet at http://www.siemens.com/sitop-ups. This website also contains further
information about the interface.
Technical specification: The USB interface is according to specification 2.0, the communication runs only with full speed, i.e. 12Mbit/s. The Interface will be supplied by the DC-UPS with +5V (“selfpowered”), signal state output every 75ms ± 20%; data output 29ms ± 20%, pause 46ms ± 20%. The connection to the PC is made by means of a usual 4-wired shielded USB-cable with a waveresistance of 90Ohm, a USB Series”A” connector to the PC and a USB Series “B” connector to the DC-UPS module and a maximum length of 5m. The cable contains two 28 to 20 AWG “nontwisted” USB-supply wires (VBUS and GND) and two 28 AWG “twisted pair” data wires (D+ and D-).
Pin assignment: Pin1: VBUS (+4.4V to +5.25V DC), transmit data on Pin2 (D-) and Pin3 (D+), Pin4: GND
Receiving data: Receive of the character “R” (Signal Remote Timerstart) starts the timer of the DC-UPS module with the set buffering time (table 2). After the set buffering time, floating operation
ends or, during normal operation, the output voltage is interrupted for 5 s if "disconnection" is set. Receipt of the character "S" (shutdown signal) starts the timer in the DC-UPS module with the set
buffering time (table 2). After the set buffering time the DC-UPS module is switched off retentively. It is restarted by disconnecting the DC supply voltage for at least 1 s. In combination with a SITOP
power supply the line voltage has to be interrupted for approx. 10 s for a restart.

Installation Instructions
In order to guarantee effective cooling, the unit must be vertically installed such that the input and output terminals and the incoming air slots are at the bottom. A clearance of at least 50 mm must
be left above and below the unit. Assembly / disassembly see page 8.
To reduce EMI and thermal strain DC-UPS modules and their battery modules should be installed at least 50cm away from commutating chokes ! Interfaces (serial, USB) and control leads (ON/OFF
control circuit) must not be laid directly in parallel to power leads or cables (especially leads between frequency converter and motor or frequency converter and commutating choke).
To minimize EMI the distance to those leads should be at least 10cm. Battery modules should be connected low-resistively (4 mm2) and in a cool place (in cubicles usually at the lower end).
If the device is to be used in a hazardous zone it must be installed in an enclosure with degree of protection IP54 or higher. This enclosure must comply with the
requirements of EN 60079-15.
Before commencing with the installation or any repair work, switch off the plant main switch and lock it in the "OFF" position. Please read the operating
instructions for SITOP power.
The fuse on the battery module must be removed before any work is carried out.
Maintenance Instructions for Battery modules
To maintain the life cycle of lead gel accumulators as long as possible, it is recommended to discharge them several times down to appr. 19V and then re-charge them (approx. 3 times discharge /
charge, discharge for instance by the DC loads of the plant, buffer time set to maximum; re-charge by DC-UPS module) at the first start-up of the machine.
With pure lead battery modules this is not necessary.
