Connecting up the mains cable on US power sourc-
es
General The US power sources are supplied without a mains cable. A mains cable appropriate for
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.

Connecting the
mains cable
Remove the left side panel of the power source
Strip about 100 mm (4 in.) of insulation from the end of the mains cable
Fit ferrules to phase conductors and the PE conductor of the mains cable; crimp fer-
rules with pliers
Undo the screws (2 x) and clamping
nut (size 30) on the strain-relief device

WARNING! Work that is carried out incorrectly can cause serious injury and dam-
age. The following activities must only be carried out by trained and qualified per-
sonnel. Pay particular attention to the "Safety rules" sections in the power source
and system component operating instructions.
NOTE! The PE conductor (green, or green with yellow stripes) should be ap-
prox. 10 - 15 mm (0.4 - 0.6 in.) longer than the phase conductors.
NOTE! If ferrules are not used, there is a risk of short circuits between the
phase conductors or between phase conductors and the PE conductor. Fit
ferrules to all phase conductors and the PE conductor of the stripped mains
cable.
