Connecting up the mains cable on MV power sources
Safety
Important! The PE conductor (green, or green with yellow stripes) should be approx. 10
- 15 mm (0.4 - 0.6 in.) longer than the phase conductors.
NOTE! If wire end ferrules are not used, there is a risk of short circuits between
the phase conductors or between phase conductors and the PE conductor. Fit
wire-end ferrules to all phase conductors and the PE conductor of the stripped
mains cable.

General If there is no mains cable attached to the power source, a mains cable appropriate for
the connection voltage must be fitted prior to putting the unit into service.
A strain-relief device for a cable cross-section AWG 10 is installed on the power source.
Strain-relief devices for other cable cross-sections must be designed accordingly.
WARNING! Operating the equipment incorrectly can cause serious injury and
damage. The following activities must only be carried out by trained and
qualified personnel. Pay particular attention to the „Safety rules“ section.
