Power supply units for 24
V supply
Only use power supply units with safe isolation and
PELV
in accordance with
EN 50178/VDE 0160. This prevents short circuits between primary and secondary sides.
Connect the GND connection on the output side of the power supply unit to the functional
ground (FE) of the system.
Ground contact Make sure that all inputs and outputs of the system are connected to the same ground.
Insulation rating When selecting the equipment, please take into consideration the dirt and overvoltages
which may occur during operation. If necessary, implement additional measures for voltage
limitation.
Installation space and
mounting position
Observe the requirements for the installation space and mounting position as specified in
the technical data.
ESD information
1.4.3 Safety of machines or systems
The machine or system manufacturer and the operator are responsible for the safety of the
machine or system and the application in which the machine or system is used.
Draw up and implement a
safety concept
In order to use the system described in this document with the associated safe blocks, you
must have drawn up an appropriate safety concept for your machine or system. This in-
cludes a hazard and risk analysis in accordance with the directives and standards specified
in section “Directives and standards” on page 15.
The target safety integrity is ascertained on the basis of the risk analysis.
– SIL in accordance with IEC 61508
– SILCL in accordance with EN 62061 (2005 + Cor: 2010 + A1:2013 + A2:2015)
– Cat./PL in accordance with EN ISO 13849-1 (2015)
The following depends on the determined safety integrity:
– The wiring of safe sensors, control devices, and actuators within the overall safety func-
tion
– The use of safe blocks in the safety logic
You can create the safety logic with the aid of the PSRmodular Software configuration
software.
Safety-related equipment In order to use the
PSRmodular system
properly, safety-related equipment must be pro-
vided on the machine.
This includes, for example:
– Emergency stop button
– Protective cover switch
– Enable switch
– Light grid
NOTE: Electrostatic discharge
Electrostatic discharge can damage or destroy components. When handling the device,
observe the necessary safety precautions against electrostatic discharge (ESD) in accor-
dance with EN 61340-5-1 and IEC 61340-5-1.
