Replacing an internal UPS battery
UPS units of the type POWERMASTER offer the option of replacing the battery while operating. One must
ensure in this case that the UPS unit is running in normal mode and not in autonomy mode. Proceed as follows
to replace the battery:
Note: Exchanging the battery could lead to a power-outage on the output, when the input-power fails
during the procedure.
1. Disconnect all battery-racks form the UPS
2. Replace the battery-racks with new ones
3. Reconnect the battery-racks
Note: Not only a single block but the complete battery should be replaced in once to ensure a proper
matching of all blocks. Echanging of single blocks shall be preformed only by skilled personnel.
