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 (for long-run models only)
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 1000, 1000L, 1500 and 1500L models, NEMA 5-20P for 2000 and
2000L models.
For Low voltage models
Note:
will be illuminated when the UPS is plugged into an improperly wired utility power outlet (Refer
to Troubleshooting section). Please also install a circuit breaker (40A) between the mains and
AC input in 3K model for safety operation.
Step 3: UPS output connection
For socket-type outputs, 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.
For terminal-type input or outputs, please follow below steps for the wiring configuration:

a) Remove the small cover of the terminal block
b) Suggest using AWG14 or 2.1mm

c) Upon completion of the wiring configuration, please check whether the wires are
securely affixed.
d) Put the small cover back to the rear panel.
