1 8.1
Perform "shutdown operations" 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.
Powering Off a Single UPS
8.2
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 based on site requirements, the UPS
downstream AC output switch.
4. Press and hold the MANUAL ON/OFF button on each lithium battery for at least 5s and less than
15s to power off the lithium battery. After all indicators turn off and fans stop, the UPS shuts
