Installation Instructions:

The LPS3WP12 should be installed in accordance with The
National Electrical Code and all applicable Local Regulations.

1.

Mount the LPS3WP12 in desired location.

2. Connect AC power to the black and white flying leads of
the transformer (Fig. 1). Use 18
connections (Battery, DC output).

3. Connect devices to be powered to terminals marked
[- DC +] (Fig. 1).

4. Measure output voltage before connecting devices. This helps av

5. Connect battery to terminals marked [- BAT +] (Fig. 1) on the power supply board (battery leads included).
Note:

When batteries are not used a loss of AC will result in loss of output voltage.
