Wiring digital inputs/outputs
1. Strip 10 mm of insulation from the wires.
2. Wire the digital inputs of the interface for connection of the sensors.
3. Wire the digital outputs of the interface for connection of the actuators.
4. Insert the cable into the corresponding spring-loaded terminal.
Using shielded cables
When using a shielded cable for the bidirectional inputs/outputs, the following options are
available for the shield connection:
1. Attach the cable shield to a grounded shielding bus immediately after the cable entry point
in the cabinet (strip the insulation off the cable for this purpose).
2. Continue routing the shielded cable as far as the module but do not make a connection to the
shield there.
Using a shield connection
1. Remove the fixing bracket of the shield connection.
2. Insert the cable and fasten the fixing bracket.
