6 Shutting down the UPS
Perform "shutdown operations" to shut down the UPS. There are two methods to shut down the
UPS:
•
On the default screen, hold down ESC for more than 5 seconds. Release the button when you
hear a beep tone. The inverter shuts down. If the bypass voltage is within the configured range,
the UPS transfers to bypass mode. If the bypass voltage is beyond the configured range, the UPS
has no output.
•
On the default screen, press to enter the CTR menu. Choose INV OFF to shut down the
inverter. The UPS transfers to bypass mode. If the bypass voltage is beyond the configured range,
the UPS has no output.
1. Shut down loads.
2. Perform "shutdown operations" on the UPS. The inverter shuts down, and the UPS transfers to
bypass mode. If the bypass voltage is beyond the configured range, the UPS has no output.
3. Open the upstream AC input circuit breaker for the UPS, the AC input circuit breakers on the rear
panel of the UPS, the AC output circuit breakers on the rear panel of the UPS (only for
professional version), the UPS AC output circuit breaker.
4. For a UPS with long backup time, you also need to open the external battery circuit breakers (if
there are) or disconnect the battery cables (if there is no battery circuit breaker). After all
indicators turn off and fans stop, the UPS shuts down and loads power off.
