Step 2 After the inverter shuts down, open the downstream output switch.
Step 3 Switch off the battery string circuit breaker. If there are multiple battery strings,
switch off the general circuit breaker between battery strings and the UPS and
then switch off the circuit breaker for each battery string.
Step 4 Turn off the upstream mains input and bypass input switches.

5.3 Cold-Starting the UPS Using Batteries

Lead-Acid Battery Cold Start
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 Turn off the mains and bypass upstream input switches, and turn on the battery
circuit breaker. If there are multiple battery strings, turn on the circuit breaker for
each battery string and then the general circuit breaker between the battery
strings and the UPS.
Step 3 Use a multimeter to measure the positive and negative battery string voltages at
the UPS battery input terminals. 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 state. The MDU
displays the Huawei logo and an initialization progress bar.
Step 5 After initialization, start the inverter on the LCD.

Lithium Battery Cold Start
Step 1 Check that the cables between the UPS and the lithium battery cabinet are
properly connected.
Step 2 Turn off the mains and bypass upstream 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.

To shut down the inverter and transfer the system to bypass mode, check that the UPS has
not reported an alarm and perform step 1.
