Liebert 610 3.3.5 Off Battery

Operation

3.3.5 Off Battery

The battery plant can be disconnected from the UPS, if required for battery maintenance, by opening

the module battery disconnect (MBD) circuit breaker. In this situation the UPS module will continue

to supply conditioned power to the critical load, but if input power fails the UPS system cannot sup-

ply power to the load.

Figure 46 Load on UPS—battery not available

!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.
