SITOP UPS1600 / BAT1600 / UPS1100
Equipment Manual, 07.2021, A5E37775406-11-76 3
Overview
The DC UPS modules supplement 24 V SITOP power supply units for interruption-free rated
currents of up to 40 A from SITOP BAT1600 and SITOP UPS1100 battery modules, which are
based on maintenance-free lead-gel or LiFePO4 batteries. With its integrated electronics,
SITOP UPS1600 automatically detects the battery type and charges it with the optimum
temperature-controlled charging characteristic curve. The intelligent battery management
monitors all relevant data, also for parallel-connected battery modules. The battery status and
various actual values, for example voltage and current, are output via the Ethernet/PROFINET
and USB interfaces. Thanks to the integrated web server, remote diagnosis is also possible.
The low profile SITOP UPS1600 DC-UPS module provides a dynamic overload behavior, e.g. to
switch on industrial PCs. The high charge 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 port Ethernet/PROFINET interfaces
•Battery modules SITOP BAT1600 24 V/3.2 Ah, 12 Ah, 38 Ah with lead-gel batteries and
SITOP BAT1600 24 V/2.5 Ah, 7.5 Ah with LiFePO4 batteries as well as SITOP BAT1600
Battery Monitor are part of the 38 Ah battery module
•24 V/1.2 Ah, 2.5 Ah, 3.2 Ah, 7 Ah and 12 Ah SITOP UPS1100 battery modules with
maintenance-free lead-gel batteries or 5 Ah with LiFePO4 batteries and integrated
electronics
•Intelligent battery management with automatic detection of the battery modules, and
selection of the optimum temperature-controlled charging characteristic; monitoring
operational readiness, battery feeder cable, aging and charge status
•All diagnostic data and alarm messages are available via USB and Ethernet/PROFINET
•Supports high dynamic overload capability: 3-fold rated current for 30 ms and 1.5-fold
rated current for 5 seconds per minute
•High charge currents

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 DIN rails (EN 60715). When installing SITOP UPS1600 devices, SITOP
BAT1600 and SITOP UPS1100 battery modules, the relevant DIN/VDE regulations or country-
specific regulations (e.g. VDE 0510 Part 2 / EN 50272-2) must be carefully complied with.
See Section Installation (Page 211)
In combination with SITOP BAT1600 and 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 s per minute, they are suitable for applications with
programmable logic controllers (PLCs) and industrial PCs, as they permit high switch-on
currents even in buffer mode.
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 SITOP BAT1600 and SITOP UPS1100 battery
modules are 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 an additional two-wire connection between the SITOP UPS1600
basic unit and the coded SITOP BAT1600 and SITOP UPS1100 battery modules. Furthermore,
the basic unit detects and manages as many as six battery modules and selects the optimum,
temperature-controlled charging characteristic curve. The latter provides the basis for the
long service life of the battery modules. Energy Storage Link also monitors the operational
readiness as well as the supply cables (wire breakage) and the charge state (voltage, current,
residual capacity) of the batteries.
Battery modules from other series and manufacturers can also be used; however, with
restricted diagnostic functions such as SoH (state-of-health) and without the temperature-
controlled charging function. To ensure optimum utilization, battery parameters must be
adapted in the HW configuration.
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 whether the output voltage is
interrupted once the set buffer time expires if, in the meantime, the input voltage returns.
For devices without interface, the interruption lasts 5 s. For devices with interface, the
interruption duration can be adjusted.

2.1 Device description
SITOP UPS1600 / BAT1600 / UPS1100
20 Equipment Manual, 07.2021, A5E37775406-11-76
For devices with software release up to V2.0.1, this function is only available for devices with
interface, as the output voltage is only interrupted after a shutdown signal is received.
For software version > V2.0.1, the interruption of the output voltage is independent of
receiving a shutdown signal.
Rotary coding switches can be used to set the battery module switch-in threshold and the
buffer time. The charge 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 27) and Operator
controls (Page 34).
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 Accessing the web server
(Page 131).
The free-of-charge SITOP Manager UPS Manager software tool, which runs on Windows XP
and Windows 7 and Windows 10 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 visualizing operating and diagnostic information, such as
in the form of alarm lists.
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 versions
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 35))
