Emergency Modules Off | Liebert Series 600T instruction

3.2.7Emergency Modules Off

The Local Emergency Modules Off (LEMO) mode is used to remove power from all UPS system components, and the critical load will continue to be supplied through the bypass line.

The Emergency Module Off control is a guarded pad on the SCC Control Panel (see Figure 10).

Lift the cover and press the pad. The load will be transferred to bypass, and the battery (MBD), input, and output circuit breakers will be opened (tripped). This will remove power from all UPS system components except the controls, system bypass circuit breaker, and the static switch.

Refer to 3.3.3 - Shutdown Procedures.
