1. Feed the wires into the terminal of the plug in accordance with the con-
nection diagram and fasten them using a screwdriver.
2. Plug the connector into the respective slot and screw it into place.
Connect the resistor contact series to the AO 4 and AI 4 interfaces in accor-
dance with the connection diagram.
You may only connect the device to circuits with an external overcurrent pro-
tective device and an all-pole isolating device, allowing the equipment to be
fully de-energized if required (service, maintenance etc.).
Suitable equipment includes isolating devices in accordance with
IEC 60947-1 and IEC 60947-3 (e.g. circuit breakers). Observe the properties
of the relevant circuits (voltage, maximum currents) when selecting the cir-
cuit breaker type. In addition, observe the following:
▪ It must be easy for the operator to access the isolating device
▪ The isolating device must be labeled for the device and the circuits to be
isolated
▪ The isolating device may not be a part of the power line
▪ The isolating device may not interrupt the main protective conductor
miniature circuit breaker must have the following properties:
▪ Rated current: 1.6 mA...16 A
▪ Triggering characteristic: B, C, K or Z
