Power Supply Voltage Output Specifications:*

Output VDC Switch Position Max. Load DC

12VDC SW1 - ON (Fig. 4b, pg. 3) 6 amp

24VDC SW1 - OFF (Fig. 4b, pg. 3) 6 amp

*Specified at 25˚ C ambient.

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. 4).

Secure enclosure to earth ground.

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

3. Connect AC power to the terminals marked [L & N], (Fig. 4, pg. 3).

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.

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

5. 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. 1, pg. 2) on PD4/CB board, terminal pairs 1 to 8 marked
