NOTE
1. After you set parameters on the Settings Wizard screen, the Bypass mode and No battery
alarms are displayed on the LCD.
2. The common buttons on the Settings Wizard screen are described as follows: Tap Previous to
return to the upper-level screen. Tap Next to go to the next screen. Tap Cancel to exit the
Settings Wizard screen.
1. System parameter settings determine normal UPS operation. Note the following:
•
Set Single/Parallel after confirmation. Otherwise, the UPS may not run properly.
•
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.
•
When a battery string is shared, the battery capacity of each UPS is the total capacity of
battery strings; when no battery string is shared, the battery capacity of each UPS is the
battery capacity of the single UPS.
•
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. 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.
