Controls and Indicators

On/Off Switch

This switch controls charger output. The switch is located on the rear of the unit and must be in the "Up" position to enable the charger.

Circuit Breaker Switch

This breaker is located on the rear of the unit and must be closed to allow the LRT Battery Cabinet to supply additional DC power to the UPS in the event of an interruption in commercial power. The switch must be in the "On" position to close the breaker.

Power Indicator (Green)

The Power indicator is located on the rear of the unit and is illuminated when the LRT Battery Cabinet is receiving commercial power and the internal charger is operating.

Summary Alarm (Red)

The Alarm indicator is located on the rear of the unit and is illuminated if the LRT Battery Cabinet has detected a problem. In addition, one or more of the UPS load/battery level indicators may be illuminated (refer to the UPS Troubleshooting Guide).

MAINTENANCE

The LRT Battery Cabinet requires very little maintenance. The batteries are valve regulated, nonspillable, lead acid, and should be kept charged to obtain their designed life. Periodically, examine the vents on the front and rear of the cabinet, and remove any obstructions from the surface of the vents.

When storing the LRT Battery Cabinet for any length of time, it is recommended to recharge the LRT Battery Cabinet for at least 24 hours every four to six months to increase battery life. In no case should the unit be stored in excess of nine months without recharge.
