Wiring diagram → 10 Technical data
► Disconnect power. Also disconnect any independently supplied relay load
circuits.
► Supply voltage: connect L+ to pin 1 and L- to pin 3 of the connector.
The nominal voltage is 24 V DC. This voltage may vary between 19.2 V and
30 V incl. 5 % residual ripple to EN 61131-2.
A safe industrial power supply with overvoltage protection must be used. In
case of a fault, 42 V AC / 60 V DC must not be exceeded.
