(Power Supply Voltage Output Selections Chart, pg. 3).
3. Securecabinettoearthground.ConnectACpower(220VAC/60Hz)totheterminalsmarked[L,G,N](Fig. 1, pg. 3).
Use14AWGorlargerforallpowerconnections(Battery,DCoutput,ACinput).
Use22AWGto18AWGforpower-limitedcircuits(ACFail/LowBatteryreporting).
Keep power-limited wiring separate from non power-limited wiring (220VAC 50/60Hz Input, Battery Wires).
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.
