NOTICE
Exceeding maximum voltage
In case of a single fault, exceeding the maximum supply voltage of
40 V DC can result in destruction of the device and loss of the safety
functionality.
►
Ensure separation of the supply voltage and transformer.
Connecting the safety sensor:
1.
Disconnect the equipment from power.
2.
If appropriate also turn off independently powered relay circuits.
3.
Connect the supply voltage: +UB to terminal 1 and 0 V to
terminal 3 of the plug.
Note
The nominal voltage is 24 V DC. This voltage may fluctuate
according to EN 61131-2 between 19.2 V and 30 V incl. 5 %
ripple.
5.1 Operation as 4-conductor
DANGER
High electrical voltage
Contact with current carrying components will result in severe injury
or death.
►
Turn off power to the device before working on it.
