5.3 Starting the UPS in Battery Mode
Procedure
Step 1 Ensure that batteries have been connected properly. Use a multimeter to check that the
absolute voltages of positive and negative battery strings are greater than a certain value
(single battery voltage x number of batteries in the battery string).
Step 2 Open the upstream mains input and bypass input switches, and close the battery circuit
breaker. If there are multiple battery strings, close the circuit breaker for each battery string
and then the general circuit breaker between battery strings and the UPS.
Step 3 Use a multimeter to measure the positive and negative battery string voltages at the UPS
battery input terminal. If the absolute values of the voltages are greater than a certain value
(single battery voltage x number of batteries in the battery string), the batteries are connected
properly.
Step 4 Press and hold down the BATT START button on the bypass module for at least 2 seconds.
The system automatically enters the battery cold start status. The LCD displays the Huawei
logo and an initialization progress bar.
Step 5 After LCD initialization, start the inverter on the LCD.

5.4 Transferring to Bypass Mode
Before shutting down the inverter, ensure that the bypass is normal. If the bypass is not
normal, after the inverter is shut down, the UPS supplies no power, and the loads shut down.
Shut down the UPS inverter. Shut down the inverter on the LCD or WebUI, and the UPS
transfers to bypass mode.
5.5 Setting ECO Mode
Prerequisites
The system is working in inverter mode.
Context
Issue 05 (2019-12-24)
If the inverter is shut down when the input voltage or frequency exceeds the specified threshold, the
UPS supplies no power, and the loads shut down.
The UPS is set to non-ECO mode by default. Set the UPS to ECO mode when energy
saving is required.
