SELECT button for 5 seconds. The UPS enters the preset mode.
Issue 08 (2017-08-04)
In the preset mode, LCD will return to the main page with 10 seconds of no operation.
If the long backup time model is not connected to an external battery pack, the buzzer
keeps buzzing.
Charge the batteries used for the first time for 5 hours. Otherwise, the battery discharge
time will decrease.
The UPS performs a battery self-check automatically once a week. If batteries are faulty,
an alarm is generated.
If the UPS is connected to the mains, when the battery packs or battery strings connect to
the UPS with long backup time for the first time, you must do a battery self-check
manually, in order to confirm the battery connection is normal. The method is: hold down
the ON/MUTE button on the front panel for 5 seconds, then the UPS transfer to battery
mode to do a shallow discharge test, after 10 seconds it automatically back to line mode.
The UPS with long backup time provides a charge current of 4 A and the current is not
configurable. If the UPS needs to connect to battery packs or battery strings, the total
battery capacity must exceed 18 Ah. Otherwise, batteries may be damaged. If the capacity
of external battery packs or battery strings to be connected exceeds 40 Ah, it is
recommended that an external charger be purchased to increase the charge current. If an
external charger is not purchased, the charge time will be long.
The 1 kVA UPS with standard backup time has two built-in batteries, the 2 kVA UPS with
standard backup time have four built-in batteries, the 3 kVA UPS with standard backup
time have six built-in batteries. If the 1 kVA UPS with long backup time needs to connect
to external battery strings, each battery string must consist of three 12 V batteries
connected in series. If the 2 kVA UPS with long backup time needs to connect to external
battery strings, each battery string must consist of six 12 V batteries connected in series. If
the 3 kVA UPS with long backup time needs to connect to external battery strings, each
battery string must consist of eight 12 V batteries connected in series.
For the UPS with standard backup time, the battery capacity has a fixed value of 9 Ah and
the charge current has a fixed value of 1 A. Set the battery capacity to the total capacity of
all batteries actually connected. Set the battery capacity for the long backup time model
based on site requirements. The default value is 7 Ah. For example, if eight batteries (9 Ah,
12 V) are connected in series to form a battery string, and two of such battery strings are
connected in parallel and then to the 3 kVA long backup time model, set battery capacity to
18 Ah (9 Ah + 9 Ah). This parameter affects the backup time calculation. Incorrect setting
will cause incorrect display of the backup time on the LCD.
During the setting of UPS parameters, press ON/MUTE for more than 3 seconds. Release the button
when you hear a beep sound to select the previous option. During the setting of UPS parameters, press
