Avoid contact with voltages.
Disconnect the plant from power before wiring. Check if the
relays are connected to voltages of external power supplies.
In order to avoid malfunction caused by interference, lay the sensor
cable separately from the load cable. Max. length of the sensor cable:
100 m.
Connection by means of Combicon connectors (fitted).
Combicon connectors are also available as accessories:
•
connector with cage clamps (order no. E40171),
•
