Eaton 93PM - Shutting down a Single UPS; Enabling and Disabling the Battery Charger; UPM Control Instructions; Starting the Upms

STARTING
ONLINE
The rectifier and inverter turn on. The DC voltage continues to ramp up to
full voltage. Once the DC link reaches full voltage and the battery breaker
is closed, the UPS output relay K3 closes. Power is now supplied to the
critical load in the double conversion mode. It takes approximately 20
seconds for the UPS system to achieve the double conversion mode.
The UPS system is now operating in the double conversion mode and the green
status indicator for normal operation is illuminated.
7.4.2 Shutting down a single UPS
A single UPS in the system can be shut down only if it is redundant. In practice,
this means that a UPS is not allowed to be shut down if doing so would lead to
an overload condition in the remaining UPSs in the system.
To shut down a single UPS:
1. In the home screen, press Controls.
The System controls screen is displayed.
2. In the System controls screen, press UPS controls.
3. In the UPS control screen, select Shut down UPS.
7.4.3 Enabling and disabling the battery charger
To turn the battery charger on or off, perform the following procedure:
1. In the home screen, press Controls.
The System controls screen appears.
2. In the System controls screen, press UPS controls.
3. Press the Turn on / Turn off button.
