When connecting external battery packs, please be sure to connect polarity correctly. Connect
positive pole of battery pack to positive pole of external battery connector in UPS and negative
pole of battery pack to negative pole of external battery connector in UPS. Polarity misconnection
will cause UPS internal fault. It’s recommended to add one breaker between positive pole of
battery pack and positive pole of external battery connector in UPS to prevent damage to battery
packs from internal fault.
The required specification of breaker: voltage ≧ 1.25 x battery voltage/set; current ≧ 50A
Please choose battery size and connected numbers according to backup time requirement and
UPS specifications.
To extend battery lifecycle, it’s recommended to use them in the temperature range of 15 ºC to 25
ºC.
