of the supply voltages US and UA accordingly, taking into account the derating
behaviour of the device:
u
Disconnect power.
u
Connect the device via port XD1 to the US supply voltage with 24 V DC (20…30 V SELV/PELV).
u
Optional: Connect the device via port XD1 to the UA supply voltage with 24 V DC (20…30 V SELV/
PELV).
u
For connection, use an L-coded M12 connector (with at least protection rating: IP65 / IP66 / IP67).
u
Tighten the cable sockets according to the torque specifications indicated by the cable
manufacturer. Maximum permissible tightening torque: 0.8 Nm
