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 .
