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 require-
ment and UPS specifications. To extend battery lifecycle, it's recommended to use them in the temperature range
of 15ºC to 25ºC.
Step 1: External battery connection
Reference the chart below to make the external battery connection.
Step 2: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
For 200/208/220/230/240VAC models: The power cord is supplied in the UPS package.
For 100/110/115/120/127VAC models: The power cord is attached to the UPS. The input plug is a NEMA
5-15P for 1K and 1.5K models, NEMA 5-20P for 2K model and NEMA 5-30P for 3K model.
Note: Check if the site wiring fault indicator lights up in LCD panel. It will be illuminated when the UPS is plugged
into an improperly wired utility power outlet (Refer to Troubleshooting section). Please also check if there is a cir-
cuit breaker against overcurrent and short circuit between the mains and AC input of the UPS for safety operation.
The recommended protection value as following:
For 200/208/220/230/240VAC models: 10A for the 1K and 1.5K models, 16A for the 2K and 3K models.
For 100/110/115/120/127VAC models: 15A for the 1K and 1.5K models, 20A for 2K model and 30A for 3K
model.
Step 3: UPS output connection
There are two kinds of outputs: programmable outlets and general outlets. Please connect non-critical devices to
the programmable outlets and critical devices to the general outlets. During power failure, you may extend the
backup time to critical devices by setting shorter backup time for non-critical
