5.4.9 Wiring DI 16-220 V digital inputs
If the device has DI 16-220 V connections, proceed as follows:
Check which version you have by looking at the connection terminal desig-
i
nation on the rear of the device.
1. Feed the wires into the terminal of the DI 16-220 V plug in accordance with
the connection diagram [►Section 8.14, Page 59] and fasten them using a
screwdriver.
2. Plug the connector into the respective slot and screw it into place.
5.4.10 Wiring digital outputs DO

1. Feed the wires into the terminal of the plug connection diagram and fasten
them using a screwdriver.
2. Plug the connector into the respective slot and screw it into place.
5.4.11 Wiring resistor contact series
Connect the resistor contact series to the COM X6 and AI 4 interfaces in accor-
dance with the connection diagram [►Section 8.14, Page 59].
5.4.12 Power supply and grounding
5.4.12.1 Connecting the power supply
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 circuit 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 iso-
lated
– The isolating device may not be a part of the power line
– The isolating device may not interrupt the main protective conductor
