The installation site should have a 120VAC power receptacle readily available to power up the unit. The unit can also be powered by –48VDC or +/–24VDC.

Power Installation

A.C. Power Installation

The ICX-250 unit is equipped with an AC receptacle located on the back of the unit.

D.C. Power Installation

When wiring to an external power source, such as a battery rack, fuse panel, or circuit breaker, make sure that the correct rating of wire is used. It is recommended you use 20 to 18 gauge wire.

Note: The ICX-250 unit can have both an AC and DC power source connected to it at the same time. These two power inputs will share the power load. However, if one fails the other will carry the full load.
