Installation Instructions:
LPS3WP12220 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. 2).
2. Mark and drill desired knockouts on the enclosure
to facilitate wiring (Fig. 1, pg. 2).
3. Secure back plate inside enclosure with the four (4)
mounting screws (Fig. 2, pg. 2).
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 and Fig. 3a, pg. 3).
Pole Mount: Refer to the detailed pole mount
instructions (pg. 3).
Secure enclosure to earth ground.
5. Connect AC power to the black and white flying
leads of the transformer (Fig. 2, pg. 2).
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. 2).
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. 2).
Note: When batteries are not used, a loss of AC will result in a loss of output voltage.
Overview:
Altronix LPS3WP12220 outdoor linear power supply/charger is specifically designed to provide the power needed
by the most demanding security and access control applications. It converts a 220VAC 50/60Hz input into a

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, 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. 3).
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. 3 and Fig. 7, pg. 3).
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. 3).
4. Thread the second wormgear quick release strap through the slots on the back of the bottom mounting
bracket (Fig. 5, pg. 3).
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. 3).
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. 7, pg. 3).
7. Clip excess straps.
