Connecting up the mains cable on US power
sources
General The US power sources are supplied without a mains cable. A mains cable appro-
priate 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 ac-
cordingly.

1
Remove the left side panel of the power source
2
Strip about 100 mm (4 in.) of insulation from the end of the mains cable
NOTE!
