Enclosure Dimensions (H x W x D):
12” x 8” x 6” (304.8mm x 203.2mm x 152.4mm).
Installation Instructions:
The LPS3WP should be installed in accordance with The National Electrical Code and all applicable Local
Regulations.
1. Remove back plate inside enclosure by removing the four (4) mounting screws (Fig. 2, pg. 5).
2. Mark and drill desired knockouts on the enclosure to facilitate wiring (Fig. 1, pg. 4).
3. Secure back plate inside enclosure with the four (4) mounting screws (Fig. 2, pg. 5).
4. Unit can be wall or pole mounted.
Wall Mount:
- Mark and drill holes to line up with the top and bottom holes of the enclosure flange.
- Secure enclosure with appropriate fasteners (Fig. 3, pg. 7).
Pole Mount:
- Refer to the detailed pole mount instructions (pg. 7).
Secure enclosure to earth ground.
5. Connect AC power to the black and white flying leads of the transformer (Fig. 2, pg. 5). Use 18 AWG or
larger for all power connections (Battery, DC output).
6. Measure output voltage at the terminals marked [–DC +] before connecting devices.
This helps avoiding potential damage.
7. Connect devices to be powered to the terminals marked [– DC +], carefully observing polarity (Fig. 2, pg. 5).
Note: Power supplies mounted in weatherproof enclosures should be derated by approximately 50% to
account for the extreme environmental conditions.
8. Connect optional stand-by battery to the terminals marked [–BAT +]. Battery leads included.
(A separate enclosure is needed for batteries). (Fig. 2, pg. 5).
Note: When batteries are not used, a loss of AC will result in a loss of output voltage.

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user
to the presence of an insulated DANGEROUS VOLTAGE within the product’s enclosure that may
be of sufficient magnitude to constitute an electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature accompanying
the appliance.
CAUTION: To reduce the risk of electric shock do not open
enclosure. There are no user serviceable parts inside.
Refer servicing to qualified service personnel.

Wall Mount Installation
1- Place unit at desired location and secure with mounting
screws (not included) (Fig. 3, pg. 7).
Fig. 3
Pole Mounting Using Optional Pole Mount Kit PMK1 (not included):
This installation should be made by qualified service personnel. This product contains no serviceable parts.
PMK1 is intended for use with Altronix outdoor rated power supplies or accessories housed in WP1, WP2, WP3
and WP4 enclosures. Brackets are designed for use with the Wormgear Quick Release Straps (two included).
1. Thread one (1) wormgear quick release strap through the slots on the back of a mounting bracket (Fig. 4, pg. 7).
2. Once the desired height of the top Pole Mount bracket is achieved, tighten the straps down by sliding open
end of the strap through the locking mechanism on the strap, then tighten the screw with
flat head screwdriver or 5/16” hex socket driver (Fig. 5, pg. 7 and Fig. 7, pg. 7).
3. Attach the bottom bracket to the enclosure by inserting bolts through the flange of the enclosure and into the
bracket, tightening bolts with a 7/16” hex socket (Fig. 6, pg. 7).
4. Thread the second wormgear quick release strap through the slots on the back of the bottom mounting bracket
(Fig. 4, pg. 7).
5. Mount enclosure onto the top bracket by inserting bolts through flange of the enclosure and into the bracket,
tightening bolts with a 7/16” hex socket (Fig. 6, pg. 7).
6. Tighten the straps of the bottom bracket down by sliding the open end of the strap through the locking
mechanism on the strap, then tighten screw with flat head screwdriver or 5/16” hex socket driver
(Fig. 4, pg. 7).
7. Clip excess straps.
