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 15ºC to 25ºC.
Step 1: External battery connection
Follow the right chart to make 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 circuit 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 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 devices.
