Installation Instructions:

The unit should be installed in accordance with The National Electrical Code and all applicable Local Regulations.

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 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. 5-6).
Secure enclosure to earth ground.

2. Slide [Power ON/OFF] switch t o OFF position.

3. Set SW1 on the power supply board to the desired DC output voltage
(Power Supply Voltage Output Specification Chart).

4. Connect AC power to the terminals marked [L & N].
Use 18 AWG or larger for all power connections (Battery, DC output).
Use 22 AWG to 18 AWG for power-limited circuits (AC Fail/Low Battery reporting).

5. Slide [Power ON/OFF] switch to ON position.

Keep power-limited wiring separate from non power-limited wiring (115/230VAC / 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.

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

6. Slide [Power ON/OFF] switch t o OFF position.

7. 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) or 1 to 8 marked [1P & 1N] through [8P & 8N] (Fig. 3, pg. 4)
or 1 to 16 marked [1P & 1N] through [16P & 16N] (Fig. 4, pg. 4), carefully observing correct polarity.
Note: Power switch is used to disconnect the L (HOT) terminal from the rest of the board. When servicing the unit,
AC mains should be removed.

8. When using stand-by batteries, they must be lead acid or gel type. Connect battery to the terminals marked
[– BAT +] (battery leads included). Use two (2) 12VDC batteries connected in series for 24VDC operation.
Note: When batteries are not used, a loss of AC will result in the loss of output voltage.

9. Connect appropriate signaling notification devices to AC Fail & Low Bat supervisory relay outputs
marked [NC, C, NO] (Fig. 1a, pg. 3).

10. Slide [Power ON/OFF] switch to ON position.

Used to notify loss of AC power, e.g. connect to audible device or alarm panel. Relay normally
energized when AC power is present. Contact rating 1A @ 120VAC / 28VDC.

Used to indicate low battery condition, e.g. connect to alarm panel. Relay normally energized
when DC power is present. Contact rating 1A @ 120VAC / 28VDC.
Low battery threshold: 12VDC output threshold set @ approximately 10.5VDC,
24VDC output threshold set @ approximately 21VDC.
