Installation

2.4Connect Power to the AC8

The AC8 must be supplied with 115VAC or 230VAC; the power supplied must match the rating of the unit’s Transformer Module. For information, consult your local dealer, Liebert representative or the Liebert Worldwide Support Group.

The AC8 must be installed on a branch circuit protected by a certified 15A overcurrent device.

! WARNING

Check that power is removed from wires prior to installation.

! CAUTION

The AC8 is designed for use on properly grounded (earthed) 115VAC or 230VAC power, 60Hz or 50Hz. The ground wire for the power lead must be wired to the earth ground terminal (stud located next to the 24VAC terminal block).

This equipment is intended to be installed by a qualified and certified electrician who must review and approve customer supplied wiring and circuit breakers, verify correct input and grounded (earthed) connections to ensure compliance with technical standards and national and local electrical codes.

! WARNING

Be sure that the Power On/Off switch is set to OFF before installing any wiring to this unit. The switch is in the top left corner of the unit, just below the battery pack.
