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.

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.
When the EPO switch is activated, all power to the critical load is lost. Use
this feature only in case of emergency.
Note: The following instructions are for the EPO switch supplied by Eaton
Corporation. If you are using a customer-supplied EPO switch, it may not
activate in the same way. For operating instructions, see the documentation
provided with the switch.
To use the EPO switch:
1.
Press the EPO pushbutton switch.
