Wiring diagram
Infeed, relay outputs and digital inputs
Maximum switching capacity per relay:
5A 250V~ ; 2A 30V=
Maximum switching capacity over all relays: 10A
This value may not be exceeded.
Do not connect any different voltages to the relay:
With 250V~ circuit: Only connect the phase conductor: Do not connect phase and neutral conductors at the relay con-
tact. With low-voltage circuit (DC): Only connect the plus pole.
