NFPA72andallapplicableLocalCodes.
1. MounttheAL1024ULXB2inthedesiredlocation/enclosure.
2. ConnectunswitchedACpower(115VAC60Hz)totheterminalsmarked[L,N](Fig. 1, pg. 2).Use14AWGorlarger
forallpowerconnections(Battery,ACinput,DCoutput).Use22AWGto18AWGforpower-limitedcircuits
(ACFail/LowBatteryreporting).
Keep power-limited wiring separate from non power-limited wiring
(115VAC / 60Hz Input, Battery Wires, DC output). Minimum 0.25” spacing must be provided.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
3. Measureoutputvoltagebeforeconnectingdevices.Thishelpsavoidingpotentialdamage.
