5.5 How to shut down the complete UPS system
The UPS system can be completely shut down if the load does not require power for an extended period of time.
1. If the UPS system is not already operating on maintenance bypass, transfer the load to the maintenance bypass and
turn OFF the UPS module(s) as described in paragraph 5.4.
2. Turn OFF power to the load equipment by opening the load isolation devices and UPS system output isolation device
on the load distribution panel.
3. Open the maintenance bypass switch
(see the IMPORTANT NOTE above)
.
4. Turn OFF the UPS input mains and bypass mains supplies at the incoming mains switchboard.
Where used, refer to the operating instructions for the bespoke external maintenance bypass facility for additional
details of how to isolate the UPS mains supply if necessary.
5. Open any external battery fuses/isolators where fitted.
6. The UPS system cabinet(s) is now voltage free.
CAUTION:
Before you carry out this procedure, warn the critical load user that power is about to be removed.
