Overview
Description
The DC-UPS modules augment the SITOP 24 V power supply units for uninterruptible rated
currents up to 20 A from the UPS1100 battery modules based on maintenance-free lead-gel
accumulators. UPS1600 with its integrated electronics detects automatically the battery type
that it charges with the optimum temperature-controlled loading characteristic curve. The
intelligent battery management monitors all relevant data, also for parallel-connected battery
modules. The Ethernet/PROFINET interface is used to output the battery status and various
current values, such as voltage, current or residual capacity. Thanks to the integrated Web
server, remote diagnosis is also possible.
The slim-line UPS1600 DC-UPS module provides a dynamic overload behavior, for example,
to switch on industrial PCs. The high charging current quickly restores the buffer readiness
after a supply system failure. And for the deployment in stand-alone operation, the UPS can
be activated from the battery for missing supply system voltage, e.g. to start the generators.
The key benefits of the product include:
● Compact SITOP UPS1600 24 V / 10 A and 20 A DC-UPS modules with digital
inputs/outputs, optional with USB or two Ethernet/PROFINET interfaces
● SITOP UPS1100 24 V / 1.2 Ah, 3.2 Ah and 7 Ah battery modules with maintenance-free
lead-gel accumulators and integrated electronics; intelligent battery management with
automatic detection of the battery modules and selection of the optimum, temperaturecontrolled charging characteristic curve; monitoring of the operating readiness,
accumulator supply cable, aging and charging state
● All diagnostic data and alarm messages are available via USB and Ethernet/PROFINET
● High dynamic overload capability: 3-fold rated current for 30 ms and 1.5-fold rated current
for 5 seconds per minute
● High charging currents
● Start from battery modules for missing supply system voltage

When operating electrical devices, it is inevitable that certain components will carry
dangerous voltages.
Therefore, failure to handle the units properly can result in death or serious physical injury
as well as extensive property damage.
Only appropriately qualified personnel may work on or in the vicinity of this equipment.
Perfect, safe, and reliable operation of this equipment is dependent on proper
transportation, storage, installation and mounting.
Before installation or maintenance work can begin, the system's main switch must be
switched off and measures taken to prevent it being switched on again.
If this instruction is not observed, touching live parts can result in death or serious injury.
The relevant DIN/VDE regulations or country-specific specifications (e.g. VDE 0510 Part 2 /
EN50272-2) must be observed for the storage, assembly and operation of the lead
accumulators. It must be ensured that the battery location is suitably ventilated. Potential
ignition sources must be separated by at least 50 cm.
The UPS1600 10 A and 20 A are built-in devices of the SITOP series for installation on DIN
EN 50022-35x15/7.5 standard mounting rails. The relevant DIN/VDE regulations or countryspecific specifications (e.g. VDE 0510 Part 2 / EN 50272-2) must be observed for the
installation of the UPS1600 devices and the UPS1100 battery modules.
See Section Installation (Page 107)
In combination with the SITOP UPS1100 battery modules, it is used to buffer the load
current from the 24 V load power supplies of the SITOP series.
With their high dynamic overload capability up to the 3-fold rated current over 30 ms or up to
the 1.5-fold rated current over 5 seconds per minute, they are suitable for applications with
programmable logic controllers (PLCs) and industrial PCs, because they permit high switchon currents even in buffer operation.
The input of the UPS1600 DC-UPS module must be connected with the output of the
supplying 24 VDC power unit. The UPS1100 battery module is connected to the Bat
terminals. The loads to be buffered are supplied via the output of the UPS1600 DC-UPS
module with the voltage connected at the input.
The so-called Energy Storage Link, an additional two-wire connection between the SITOP
UPS1600 base device and the coded SITOP UPS1100 battery modules, is new.
Furthermore, the base device detects and manages as many as six battery modules and
selects the optimum, temperature-controlled charging characteristic curve. The latter
provides the basis for a long service life of the battery modules. Energy Storage Link also
monitors the operational readiness as well as the supply cables (wire breakage), aging
(service life) and the charging state (voltage, current, residual capacity) of the accumulators.
The connection to the UPS1100 battery modules is checked every 20 seconds (for voltage
and incorrect polarity protection). A test with a defined loading of the lead accumulators is
also performed automatically every four hours.
Battery modules of other type series and manufacturers can also be deployed, although with
limited diagnostic functions, such as the display of the charging current or the end-of-charge
voltage and without the possibility of temperature-controlled charging.
In the event of failure of the 24 VDC supply voltage or voltage dip below the set switch-in
threshold, the loads are supplied from the battery module that is kept full charged in parallel,
ready for operation. The buffering is performed in accordance with the backup time set using
the rotary coding switch or until the maximum backup time (shutdown after reaching the
exhaustive discharge threshold).
There are two possibilities:
a.) Power restoration only after expiration of the backup time: On absence of the input
voltage at the DC-UPS module, the battery immediately assumes the supply so that the Ua
output voltage remains absolutely interruption-free until the end of the backup time.
b.) Power restoration before expiration of the backup time: On absence of the input voltage
at the DC-UPS module, the battery immediately assumes the supply so that the Ua output
voltage remains absolutely interruption-free. If the "Interruption of the output voltage" setting
is selected (see Chapter Jumper variants (Page 22)), the Ua output voltage is interrupted
automatically for the parameterized time (default value 5 seconds) on supply system
restoration during the parameterized backup time. The accumulator is already disconnected
because the input voltage has already returned. If "Ua output interruption" is set, no
interruption occurs because the input voltage has returned before expiration of the set
backup time.
Rotary switches can be used to set the battery module switch-in threshold and the backup
time. The charging current for the battery modules is set automatically and can be changed
using the interface (only for types -1AY0 and -2AY0).
Eight LEDs, two potential-free changeover contacts and one NO contact indicate the
UPS1600 status.
The USB interface (only -1AY0) or PROFINET/Ethernet interface (only -2AY0) handles the
communication to the PC/controllers.
For details, see Sections Connections and terminal designation (Page 15) and Switches and
buttons (Page 20).
Operating data and diagnostic data can be transferred using two integrated Industrial
Ethernet/PROFINET ports and visualized or further processed externally as an alternative to
the proven USB connection. An integrated Web server allows authorized users to export
relevant data remotely via a Web browser without requiring any additional software to be
installed on the remote system. The Web server is activated in the delivered state.
The free SITOP UPS Manager software tool available for Windows XP and Windows 7
systems (32- and 64-bit) provides full access. This allows the overall DC-UPS installation to
be configured and monitored easily using a PC. The software tool provides many
possibilities for the visualization of operating and diagnostic information, such as in the form
of alarm lists or easily understandable trend diagrams that, for example, provide a view of
the chronological change of the charging voltage or load current of the DC-UPS.
The UPS Manager also detects when older SITOP DC-UPS modules (6EP1931-2xxxx) are
deployed and displays them correctly.
The SITOP UPS1600 is fully integrated in Totally Integrated Automation (TIA), the Siemens
open system architecture for integrated automation solutions. The engineering is performed
in the TIA Portal and reduces to just a few clicks for the user. The UPS modules can be
selected directly in the hardware catalog and in the graphical network representation
accepted.
For applications without network connection, the SITOP UPS1600 is available in the variants
with USB interface or digital inputs/outputs.
For stand-alone deployment, the DC-UPS can be activated without input voltage from the
battery, for example, to start a generator via a directly supplied controller. (see Section
Jumper variants (Page 22))

2.2 Connections and terminal designation
The UPS1100 battery modules consist of a battery holder with two maintenance-free, closed
lead-gel accumulators with terminals for the connection cables to the SITOP UPS1600
uninterruptible power supply. The UPS1100 contains a printed-circuit board for monitoring
the battery functions and the communication with the UPS1600. A green LED lights
continually to indicate that there is a communication connection to the UPS1600 or flashes
during the accumulator replacement.
As many as six UPS1100 of the same type can be connected in parallel with a UPS1600.
For an accumulator replacement, see Section Battery replacement (Page 112).
The USB interface (type B) ⑥ conforms fully to the USB 2.0 standard (12 MBd). Strain relief
(see Section USB connector (Page 98)) is implemented using a defined cable/connector
(Y-Con USB - Yamaichi company).
Ethernet interface ⑤ corresponds to the standard full duplex with up to 100 Mbit/s electrical
(100BASE-TX) according to IEEE 802.3.
Properties of the Ethernet interface:
● Transmission rate 10/100 Mbit/s
● Two RJ45 sockets, i.e. integrated switch, for RJ45 connector
● Cable type 100Base-TX (CAT5)
● Auto negotiation
● Auto crossover communication via TCP/IP and PROFINET
The strain relief (see Section PROFINET/Ethernet connector (Page 99)) is implemented
using a Siemens IE FastConnect RJ45.
The physics of the Ethernet interface is implemented so that PROFINET IO is possible in
accordance with the standards IEC 61158 and IEC 61784-2. For PROFINET, conformance
class B must be maintained as a minimum.
The Ethernet/PROFINET interface permits:
● Configuration and monitoring using the SITOP UPS Manager
● Monitoring via the Web server
● Integration and communication of the DC-UPS with other automation components from
Siemens and the open environment, e.g. IPC, PLC, HMI
● Firmware update of the device via UPS Manager or STEP 7
It is only permissible to actuate the rotary coding switch using an insulated screwdriver.
2.3 Switches and buttons
The switch-in threshold can be set using the rotary coding switch ⑦ on the device front
between 21.0 V and 25-0 V (21 - 21.5 - 22 - 22.5 - 23 - 24 - 25 volt). The delivery state is
22.5 V
For devices with an interface (…-1AY0, …-2AY0), the coding switch has an additional
position (REN, see the following figure). If this is selected, the software settings (for the
switch-in threshold and the backup time) apply rather than the hardware settings. In the
switch position REN, the connection X2.13 (INTERRUPT - reset after buffer operation) of the
signal terminal (see Section Signal terminal (Page 16)) has no effect.
It is only permissible to actuate the rotary coding switch using an insulated screwdriver.
2.3 Switches and buttons
The backup time is set using the rotary coding switch ⑧ on the device front between
30 seconds and MAX (32767 seconds) in the steps 0.5 minute (30 seconds), 1 minute,
2 minutes, 5 minutes, 10 minutes, 20 minutes and MAX (32767 seconds). Delivery state is
MAX
The coding switch has an additional setting OFF (see following figure). If this is selected and
the additional threshold rotary coding switch is not set to REN, the buffering is disabled.
If the backup time is also set using the software (only for devices with an interface (…-1AY0,
…-2AY0)) (possible setting range, see Section Parameterizing the UPS in STEP 7 V5
(Page 61)), the rotary coding switch for the switch-in threshold (see Section Rotary coding
switch, switch-in threshold (Page 20)) must be set to REN.

2.3 Switches and buttons
The wire jumper on the signal connector ④ between pin 9 and pin 10 (see Figure 2-4 Signal
connector (Page 16)) is used to enable/disable the buffer mode.
Buffer mode is only possible if the wire jumper ON/OFF is closed, or for UPS1600 devices
with interface, also if the rotary coding switch connection threshold is at the "REN" position.
From firmware release V1.20, the wire jumper ON/OFF has priority over the position of the
connection threshold rotary coding switch.
As a consequence, it is possible to enable or disable buffer mode using a floating contact
(e.g. a contact in the plant or system). The contact is switched instead of the ON/OFF wire
jumper. (Note: For reasons relating to noise insensitivity, approximately in the range
5...10 mA, Umax = 15 VDC, SELV: Imax = 10 mA)

Changes are also effective in the buffer mode.

Delivery state: Wire jumper between pin 9 and 10
A wire jumper on the signal connector ④ between pin 13 and pin 10 is used to
enable/disable the interruption of the output voltage for the parameterized time (default value
5 seconds) for supply system restoration during the buffer time.
To prevent data losses, the PCs must be shut down timely before the buffer time ends. If the
input voltage returns after the shutdown has already started, buffer mode is ended and the
UPS1600 goes into normal operation. The PC will be shut down, however, it is not switched
off. PCs, which do not have an on/off switch, can only be rebooted by switching off the power
and switching on again.
For customers that use their own software, this pulse must be selected at the DC UPS
module.
The start from the battery is initiated by closing the contact pin 14 to ground (pin 10). This
jumper must not provide a permanent connection, but must be controlled using a button. The
input is designed so that a single lamp with a permissible supply voltage of between 12 and
30 V and 8 to 15 mA can be switched in series to the switching contact. If while pressing the
button, the UPS1600 enters buffer mode, the set buffer time will be started. For example, if
5 minutes is set, the UPS1600 sets itself off after 5 minutes. If the input voltage returns
during the buffer time, the UPS1600 switches to normal operation.
If the input voltage is available, the DC UPS starts in the normal operation.
If the UPS1600 is switched-off remotely via the interface (also possible when input voltage is
available), start from the battery can be used to restart the UPS1600.
For uncoded batteries, the size of the charge current can be changed by placing jumpers
between the terminals X2.10 (ground) and X2.11 or X2.12.
