5.3 Starting the UPS in Battery Mode

Lead-Acid Battery Cold Start
Step 1 Ensure that batteries have been connected properly. Use a multimeter to check
that the voltage of a battery string is greater than a certain value (single battery
voltage x number of batteries in the battery string).
Step 2 Turn off mains input circuit breaker 1 (Q1-1), mains input circuit breaker 2 (Q1-2),
and bypass input switch (Q2). 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 battery strings and the UPS.
Step 3 Use a multimeter to check that the voltage of battery strings at the UPS end is
greater than a certain value (single battery voltage x number of batteries in the
battery string), which indicates that 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.

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 mains input circuit breaker 1 (Q1-1), mains input circuit breaker 2 (Q1-2),
and bypass input switch (Q2).
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.
