This chapter provides detailed operating procedures of the UPS.
5.1 Brief Introduction
5.1.1 Precautions
Important
The user can conduct relative operation only after the authorized engineer carries out the first power on and test.
Warning: hazardous mains and/or battery voltage
1. The components that can only be accessed by opening the protective cover with tools cannot be operated by the
user. Only qualified service personnel are authorized to remove such covers.
2.
The AC input and output terminals of UPS have dangerous voltage at any time. If the cabinet is equipped with an EMC
filter, the filter may have dangerous voltage.
1. For the control keys and LCD related to all the operating steps, refer to Chapter 4 Operator Control And
Display Panel.
2. During operation, the buzzer alarm may occur at any time. Press SILENCE ON/OFF key to silence the audible
alarm.
3. When UPS uses traditional lead-acid battery, the system provides boost charge optional function. If the
lead-acid battery is used, when the mains returns after an extended mains failure, the charging voltage of the
battery will be higher than the normal charging voltage, this is normal, and the charging voltage of the battery
will return to normal value after a few hours' charging.
Warning: hazardous mains and battery voltage present behind covers
No user-serviceable parts are located behind covers that require a tool for their removal. Only qualified service
personnel are authorised to remove such covers.
