Wiring terminal strips
Solid or flexible cables are permitted as signal lines. Wire end ferrules must not be used for
the spring-loaded terminals.
The permissible cable cross-section ranges between 0.5 mm² (21 AWG) and 1.5 mm² (16
AWG). When completely connecting-up the unit, we recommend cables with a cross-section
of 1mm² (18 AWG).
Route the signal lines so that you can again completely close the front doors after
connecting-up the terminal strip. If you use shielded cables, then you must connect the
shield to the mounting plate of the control cabinet or with the shield support of the inverter
through a good electrical connection and a large surface area.
