Step 3 Use a multimeter to measure the voltage of each battery string connected to the
UPS. If the voltage is greater than the specified value (Voltage of a single battery
x Number of batteries in the battery string), batteries are connected properly.
Step 4 Press and hold down the BATT START button on the bypass control module for
more than 2 seconds. The system automatically enters the battery cold start state.
The MDU displays the Huawei logo and an initialization progress bar.
