Off Battery | Liebert Series 600T manual

3.2.6Off Battery

The battery plant can be disconnected from the UPS modules, if required for battery maintenance, by opening the module battery disconnect (MBD) circuit breaker(s). In this situation the UPS system will continue to supply conditioned power to the critical load, but if input power fails, the UPS system cannot supply power to the load.

CAUTION

When the UPS system is operating with the module battery disconnect (MBD) circuit breaker(s) open, the critical load is not protected from loss of the utility source power.
