AC Line Attachment
The AC power supply may either be 115V or 240V depending on the unit require-
ments. AC line power is supplied to the 3-wire AC panel module socket by means
of the 10 foot (3.05 m) cable and matching socket that is furnished with the equip-
ment. The third wire in the cable, coded green/yellow, is the ground wire.
Note:
For proper protection, if a 3-wire type plug and outlet is not
used, fasten the green/yellow wire at the supply end to a satisfactory
ground.
Before applying AC power to the unit, make sure:
