Installation Instructions:
The LPS3C24X should be installed in accordance with The National Electrical Code and all applicable Local
Regulations.
1. Mount the LPS3C24X in desired location.
2. Connect AC power to the black and white flying leads of the transformer (Fig. 1).
Use 18 AWG or larger for all power connections (Battery, DC output).
3. Measure output voltage before connecting devices. This helps avoid potential damage.
4. Connect devices to be powered to terminals marked [- DC +] (Fig. 1).
5. Connect battery to terminals marked [- BAT +] (Fig. 1) on the unit (battery leads included).
Note: When batteries are not used a loss of AC will result in loss of output voltage.
