10.3. Wiring

Caution
●To prevent damage, all power for the SI Unit and modules must be turned off (i.e. de-energized) before
the modules are installed or removed.
●For a protection rating of IP65 to be ensured, sockets that are not used must be closed with M12 covering
caps.
●For a protection rating of IP65 to be ensured, all covering caps must be screwed down correctly after
wiring and setting have been performed.

WARNING: Loss of safety function
Parasitic voltages can result in the loss of the safety function.
●Connect the sensor ground directly to Pin 3 0V (US1) of the safety module. An external ground may not
be used.
