Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Power supply system SITOP PSU8600
Manual, 09.2018, A5E36758446-5-76 3
Overview
The SITOP PSU8600 power supply system is the high-performance, regulated technology
power supply system for automated plants and machines.
The key benefits of the product include:
●Wide-range input, which allows them to be connected to almost all 3-phase line supplies
around the world
●Number of outputs can be expanded using up to four expansion modules SITOP
CNX8600
●The output voltage of each output can be adjusted in the range 4 - 28 V
●Electronic overload shutdown for each output, the response threshold can be adjusted;
alternatively: electronic current limiting (constant current), current can be adjusted
●integrated Ethernet/PROFINET interfaces (2 port switch)
●Diagnostics data and alarm messages available via Ethernet/PROFINET
●Outputs can be switched – controlled from a program – and parameterized via
Ethernet/PROFINET
●Completely integrated in TIA: user-friendly engineering in SIMATIC STEP 7 and
SIMATIC STEP 7 in the TIA Portal,
S7 function blocks for integration in user programs and WinCC faceplates
●OPC UA interface for non-proprietary communication in automation systems
●Remote monitoring via the integrated web server
●Brief overload capability of 150 % for 5 s/min (Extra Power)
●Low width and high efficiency
●Rail mounting and connection using plug-in terminals

Overview
Power supply system SITOP PSU8600
4Manual, 09.2018, A5E36758446-5-76
●Short power failures can be buffered using maintenance-free SITOP BUF8600 buffer
modules with electrolytic capacitors or double layer capacitors
●Longer power failures can be buffered using the SITOP UPS8600 UPS module and
SITOP BAT8600 battery module (either using lead acid or lithium iron phosphate
batteries)

Safety instructions
WARNING
Correct handling of the devices
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.

Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. You can find more information about industrial security by visiting:
https://www.siemens.com/industrialsecurity (https://www.siemens.com/industrialsecurity.).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends you apply product updates as soon as available and
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.

2.1
Description of the basic devices
The basic units SITOP PSU8600 are primary-clocked power supplies for connection to 3-
phase AC line supplies. An electronically controlled DC voltage that can be set via a
potentiometer is available at the output of the devices. The device output is isolated, no-load
and short-circuit proof and has an electronic overload trip - or alternatively overload current
limiting (constant current), which can be set using an additional potentiometer. The device
output is switched-on and switched-off using a button.
LEDs signal the operating state of the device as well as that of the output. The electronic
overload shutdown is reset using the reset input and the button of the output. Additional
device functions are activated using DIP switches.
The device output is controlled and operating and diagnostics data transferred and externally
visualized or processed via the two integrated industrial Ethernet/PROFINET ports. An
integrated web server allows authorized users to read and write data remotely via a web
browser. Further, an OPC UA server is integrated in the devices (Open Platform
Communications Unified Architecture). This facilitates non-proprietary communication in
automation systems.
Add-on modules expand the functions of the basic units:
●Expansion modules are used to increase the number of outputs.
●Buffer modules buffer brief power failures for up to several seconds.
●A UPS module and connected battery module buffer extended power failures up into the
hours range.
A basic unit can be expanded
●With a maximum of 4 expansion modules (to provide a maximum of 33 outputs, including
the basic unit)
●With a maximum of 2 buffer components (2 buffer modules, 1 buffer module and 1 UPS
module – or 2 UPS modules)
●With a maximum of 6 supplementary modules in the system.

2.2
Description of the expansion modules
Using a SITOP CNX8600 expansion module, the number of system outputs can be
increased, however, not the maximum output power of the basic unit. The expansion
modules, just like the basic unit, have potentiometers for setting and buttons to switch-on
and switch-off the relevant output. LEDs signal the operating states of the expansion module
as well as the individual outputs. A maximum of four expansion modules can be used for
each basic unit. The integrated plug connector connects the module with the basic unit or the
adjacent module.
