Lithium Battery Cold Start
Step 1 Check that the cables between the UPS and the lithium battery cabinet are properly connected.
Step 2 Open the upstream mains input and bypass input switches.
Step 3 Power on the lithium battery cabinet. For details, see the user manual for the lithium battery
cabinet.
Step 4 Use a multimeter to measure the voltages of the positive and negative battery strings
connected to the UPS battery input terminals. If the measured values are consistent with the
voltages displayed on the System Status screen of the lithium battery cabinet, the batteries
are properly connected.
Step 5 Check that the green indicator on the battery control unit in the lithium battery cabinet blinks
at 1 Hz or is steady on. Then, 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 6 After LCD initialization, start the inverter on the LCD.

5.7 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, and the UPS transfers to
bypass mode.

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.
When the UPS works in ECO mode, the bypass module takes precedence over the power
module in supplying power to loads. When the bypass module is disconnected, the UPS
switches to the power module. The switchover time is less than 4 ms for typical working
conditions and is no more than 20 ms for harsh working conditions.
The ECO mode delivers a higher efficiency.
To avoid frequent transfer between ECO mode and normal mode, do not set the ECO
mode when the bypass input is unstable or is sensitive to load changes.
