7.5.2 Shutting down the UPMs
A single UPM in the system can be shut down only if it is redundant. In practice,
this means that a UPM is not allowed to be shut down if doing so would lead to
an overload condition in the remaining UPMs or UPSs in the system.
To shut down a single UPM:
1. In the home screen, press Controls.
The System controls screen is displayed.
2. In the System controls screen, press Module controls.
The Select module screen is displayed.
3. Select the UPM you want to shut down.
4. In the UPM control screen, select Shut down module.
7.6 Using the Remote Emergency Power-off switch
A UPS emergency power-off is initiated by the EPO pushbutton switch. In case
of an emergency, you can use this switch to control the UPS output. The EPO
switch de-energizes the critical load and powers down the UPS immediately
without asking for verification. The UPS, including the static bypass switch,
remains off until it is restarted.
