Installation Instructions:

Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all local
codes and authorities having jurisdiction. Product is intended for indoor use only.

1. Mount unit in the 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 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, pgs. 6).
Secure enclosure to earth ground.

2. Connect AC power to the terminals marked [L & N], connect ground to the terminal marked [G] (if used),
(Fig. 1, pg. 4 or Fig. 4, pg. 5). Use 18 AWG or larger for all power connections (Battery, DC output).

Keep power-limited wiring separate from non power-limited wiring (115VAC / 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.

3. Measure output voltage before connecting devices. This helps avoiding potential damage.

4. Connect devices to be powered:
a. For Power Supply Board connect to the terminals marked [--- DC +].
b. For Power Distribution Module(s) connect devices to be powered to the terminal pairs 1 to 4 marked
[1P & 1N] through [4P & 4N] (Fig. 2, pg. 4), 1 to 8 marked [1P & 1N] through [8P & 8N] (Fig. 3, pg. 4),
or 1 to 16 marked [1P & 1N] through [16P & 16N] (Fig. 5, pg. 5) carefully observing correct polarity.

5. When using stand-by batteries, they must be lead acid or gel type. Connect battery to the terminals marked [--- BAT +]
(battery leads included) (Fig. 1, pg. 4 or Fig. 4, pg. 5).
Note: When batteries are not used, a loss of AC will result in the loss of output voltage.

6. For Supervised Models Only:
Connect appropriate signaling notification devices to AC Fail & Low Bat supervisory relay outputs marked
[N.O., C, N.C.] (Fig. 1a, pg. 4, Fig. 4a, pg. 5).
