the connection voltage must be fitted prior to commissioning.
A strain-relief device for a cable cross-section AWG 10 is installed on the power source.
Strain-relief devices for larger cable cross-sections must be designed accordingly.

The ground conductor (green, or green with yellow stripes) should be approx. 10 -
15 mm (0.4 - 0.6 in.) longer than the phase conductors.
Fit ferrules to phase conductors and the ground conductor of the mains cable; crimp
ferrules with pliers
CAUTION!
