Requirements for connecting the cable for the supply voltages
● The supply voltages are turned off.
● Color coding labels (Page 77) (optional) have been applied.
Tools required
Depending on conductor type
● Single wire without ferrule: Toolless
● Multi-core (stranded wire) with ferrule or ultrasonic compacting:
Suitable tool to prepare the cable.
● Multi-core (stranded wire) without ferrule, unprocessed: 3 to 3.5 mm screwdriver
Read the section "Wiring rules (Page 85)".
