Installation Instructions:

The LPS3C24X220 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.

1. Mount LPS3C24X220 in the desired location.

2. Connect AC power to the black and red 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 avoiding potential damage.

Keep power-limited wiring separate from non power-limited wiring (220VAC 50/60Hz Input, Battery Wires).

Minimum 0.25” spacing must be provided.

CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.

There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.

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

5. Connect battery to the terminals marked [- BAT +] (Fig. 1) as marked on the unit (battery leads included).

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

Maintenance:

Unit should be tested at least once a year for the proper operation as follows:

Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level

(see power supply voltage output specifications chart).

Battery Test: Under normal load conditions, check that the battery is fully charged, check specified voltage both at battery terminal and at the board terminals marked - BAT + to ensure that there is no break in the battery connection wires.

Note: Maximum charging current under discharge is 500mA.

Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
