1. Mount unit in desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the

enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s
upper keyholes over the two upper screws, level and secure. Mark the position of the lower two holes. Remove the
enclosure. Drill the lower holes and install the three fasteners. Place the enclosure’s upper keyholes over the two
upper screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 7-8).

2. The power supply is pre-wired to the ground (chassis). Connect main incoming ground to the provided green

grounding conductor lead. Connect unswitched AC power (220VAC 50/60 Hz to terminals marked [L, G, N]
(Fig. 1, pg. 3 & Fig. 2, pg. 4). Use 14 AWG or larger for all power connections (Battery, DC output, AC input).
Use 22 AWG to 18 AWG for power-limited circuits (AC Fail/Low Battery reporting).
Keep power-limited wiring separate from non power-limited wiring (220VAC 50/60Hz Input, Battery Wires).
