SITOP UPS1600 / UPS1100
Manual, 04.2016, A5E37775406-6-76 3
Overview
Description
The DC-UPS modules augment the SITOP 24 V power supply units for uninterruptible rated
currents up to 40 A from the UPS1100 battery modules based on maintenance-free lead or
LiFePo batteries. SITOP UPS1600 with its integrated electronics automatically detects the
battery type that it charges with the optimum temperature-controlled charging 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 actual values, such as voltage and current. Thanks to the integrated web
server, remote diagnosis is also possible.
The low profile SITOP 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, 20 A and 40 A DC-UPS modules with digital
inputs/outputs, optional with USB or two Ethernet/PROFINET interfaces
●SITOP UPS1100 24 V/1.2 Ah, 2.5 Ah, 3.2 Ah, 7 Ah and 12 Ah battery modules with
maintenance-free lead-gel batteries or 5 Ah with LiFePo batteries and integrated
electronics; intelligent battery management with automatic detection of the battery
modules and selection of the optimum, temperature-controlled charging characteristic
curve; monitoring of the operating readiness, battery 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

2.1
Device description
2.1.1
SITOP UPS1600
The SITOP UPS1600 10 A, 20 A and 40 A are built-in devices of the SITOP series for
mounting on TH35-15/7.5 standard mounting rails (EN 60715). When installing the
SITOP UPS1600 devices and SITOP UPS1100 battery modules, the relevant DIN/VDE
regulations or country-specific regulations (e.g. VDE 0510 Teil 2 / EN 50272-2) must be
carefully complied with.
See Section Installation (Page 149)
In combination with the SITOP UPS1100 battery modules, they are 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 300% rated current for 30 ms or up to
the 150% rated current for 5 seconds per minute, they are suitable for applications with
programmable logic controllers (PLCs) and industrial PCs, because they permit high switch-
on currents even in buffer operation.
The input of the SITOP UPS1600 DC-UPS module must be connected with the output of the
supplying 24 V DC power supply unit. The UPS1100 battery module is connected to the BAT
terminals. The loads to be buffered are supplied via the output of the SITOP UPS1600 DC-
UPS module with the voltage connected at the input.
The Energy Storage Link is new. This is an additional two-wire connection between the
SITOP UPS1600 base device and the coded SITOP UPS1100 battery modules.
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. The Energy Storage Link
also monitors the operational readiness as well as the supply cables (wire breakage) and the
charge state (voltage, current) of the rechargeable batteries.
The connection to the SITOP UPS1100 battery module is checked every 20 seconds (for
voltage, reverse polarity protection). A test with a defined load of the lead or LiFePo batteries
is also performed automatically every four hours (basic setting).
Battery modules of other type series and manufacturers can also be used, 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 V DC supply voltage or voltage dip below the set switch-in
threshold, the loads are supplied by switching over to the battery module. Buffering is
realized until the line supply returns or until the buffer time, set using the rotary coding
switch, has expired. If the buffer time has been set to MAX, then shutdown is realized when
the exhaustive discharge threshold is reached.
Using the output voltage interrupt function you can select as to whether the output voltage is
interrupted once the set buffer time expires if, in the meantime, the input voltage returns.

14 Manual, 04.2016, A5E37775406-6-76
(Delivery state: the output voltage is not interrupted). For devices without interface, the
interruption lasts 5 s. For devices with interface, the interruption duration can be adjusted.
For the "Maximum buffer time" setting, the output voltage is only interrupted by the UPS
Manager. In this case, the rotary coding switch "Connection threshold" must be set to REN.
Rotary switches can be used to set the battery module switch-in threshold and the buffer
time. The charging current for the battery modules is set automatically, and can be changed
using the interface (only for types -1AY0 and -2AY0), as well as via the signal connector.
Eight LEDs, two potential-free changeover contacts and one floating NO contact indicate the
SITOP 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 17) and Operator
controls (Page 22).
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. When delivered, the web server is not active (applies from
version V2.1 and higher). Using the two rotary coding switches, the web server can be
activated, and a temporary Internet address assigned, see SITOP UPS1600 (Page 22).
The free-of-charge SITOP UPS Manager, which runs on Windows XP and Windows 7
systems (32 and 64 bit), allows 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 which, for example, provide a view of the
chronological change of the charging current or load current of the DC-UPS at a glance.
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 transferred into the graphic network
representation.
For applications without network connection, the SITOP UPS1600 is available in the variants
with USB interface or digital inputs/outputs.
For stand-alone operation, the DC-UPS can be activated without input voltage from the
battery, for example, to start a generator via a directly supplied controller. (see Chapter
Jumper variants (Page 23))

SITOP UPS1100
The SITOP UPS1100 battery modules consist of a battery holder with two maintenance-free,
closed lead or LiFePO batteries 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 SITOP UPS1600.
A green LED lights continually to indicate that there is a communication connection to the
SITOP UPS1600. The LED flashes when the batteries are being replaced or for faults and
alarms.
Up to 6 SITOP UPS1100 of the same type can be connected in parallel with a
SITOP UPS1600.
When replacing a battery, see Chapter Battery replacement (Page 153).

Properties of the Ethernet interface:
●Transfer 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 141)) is implemented
using a Siemens IE FastConnect RJ45.
The physics of the Ethernet interface is implemented so that PROFINET IO according to
standards IEC 61158 and IEC 61784-2 is possible. 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, web server or STEP 7
