AC units can be connected into a standard 15 Amppowerreceptacleofthepropervoltageviathepowersupply.Makesurethepowercircuitis properly grounded. Two power cords are supplied, one 115 Vac American and one 240 Vac International.

CAUTION:

This unit is designed for connection to a single phase power source . Connection to a 3 phase power source will cause significant damage to internal components .

CAUTION:

Proper electrical connection is required . It is suggested a licensed electrician be contracted to connect the AC wiring to the unit, if it is connected directly to the mains . Failure to properly connect the power wires could result in a dangerous electrical shock hazard .
