1. After you set parameters on the Settings Wizard screen, the Bypass mode and No battery
alarms are displayed on the LCD.

1. System parameter settings determine normal UPS operation. Note the following:
•
Set Single after confirmation. Otherwise, the UPS may not run properly.
•
Output voltage level refers to the line voltage level. Set it based on the site requirements.
•
Set Output frequency correctly; otherwise, loads may not work properly.
2. Battery parameter settings have great impact on battery maintenance, battery lifespan, and
UPS discharge time. When you set battery parameters, note the following:
•
Set Battery capacity after repeated confirmation. An incorrect setting reduces the charging
power.
•
A high or low charging power tends to shorten the battery lifespan, or even damages
batteries. If you do not know how to confirm the battery capacity, contact Huawei technical
support.
•
Number of cells indicates the number of 2 V DC cells connected to the UPS. Each cell is 2
V. For example, if a battery provides a voltage of 12 V, it is regarded as six cells. If each
battery provides a voltage of 2 V, the number of cells is the same as the number of
batteries. The following table lists examples of setting battery parameters. Number of cells
affects the charge voltage and discharge time. Incorrect setting will cause a high or low
charge voltage, which greatly shortens the battery lifespan. In addition, the UPS may shut
down before the discharging is completed, which may result in data backup failure.
No: ATS input
Commission the ATS by following the
is used.
instructions in chapter 7 "ATS Commissioning
Before System Power-On".
•
Before powering on the UPS, check that the
ATS is in electric mode (ATS input).
•
Before powering on the UPS, check the two
indicators. When the ATS is in manual mode,
check that the switch is in manual mode and
that the UPS work line matches the handle
line.
