1.3 Electrical safety
Direct/indirect contact Protection against direct and indirect contact according to DIN VDE 0100-410 must be
ensured for all components connected to the PSR-TRISAFE-S safety module. In the event
of an error, parasitic voltages must not occur (single-fault tolerance).
Safe isolation Only use devices with safe isolation if hazardous contact voltages can occur at their
connections.
Power supply unit Only use power supply units with safe isolation and PELV according to
DIN EN 50178/VDE 0160 (PELV). This prevents short circuits between primary and
secondary sides.
ESD
DANGER: Hazardous body currents or the loss of functional safety.
In order to ensure electrical safety, please observe the following points and the
information in the user manuals for the devices used (e.g., sensors, actuators or
extension units).
NOTE: Electrostatic discharge
The device contains components that can be damaged or destroyed by electrostatic
discharge. When handling the device, observe the necessary safety precautions against
electrostatic discharge (ESD) according to EN 61340-5-1 and EN 61340-5-2.
