4INSTALLATION
4.1 Input
1. Forbid using general household sockets, the maximum current of
general sockets is 15A, the socket may cause fire because of overload.
2. Turn off power when connecting cables, prohibit operation on live
wires.
3. Please connect UPS input terminal to utility power from a switchboard.
Figure 11.
Note: Do not swop live and neutral
4. Back panel position and connection
(1) Remove two screws with “+” screwdriver (Figure 12)
(2) Open the back panel and inspect the wiring terminal below the
power switch. (Figure 13)
5. Feed in the input, output and battery pack power cables through the
inlet/outlet hole and connect to the terminal block on the UPS.

Figure 12
Figure 13
6. Connect power correctly
(1) Live (L): There is 220V relative to other two holes.
(2) Neutral (N): there is 220V relative to the Live, there is 0.5-2V
relative to the ground. (Load current circulate through neutral)

-13-
(3) Ground (G): Connect correctly to ground in the switchboard.
7. If the difference between the neutral and the ground is more than 2V
or it cannot meet the requirements, please reinstall good grounding to
ensure safety of UPS operation.

9. The power cable and terminal must be a first-grade product
manufactured by an authentic manufacturer.
10. Do not wrap the power cables around the terminal block screws.
11. After fastening the input cable, to avoid short-circuit, please see if the
input cable contacts properly and does not touch other wiring.
12. Follow the electrical laws when doing installation.
13. Avoid using the same circuit breaker with other equipment when
connecting to the switchboard.

-14-
14. For 3Ø 4-wire connections,
please respectively measure
the voltage between R/N,S/N,
T/N with a meter and see if
they are close to 220V, then
connect L cable of the UPS to
the cable whose voltage
measured the highest
(meaning supply power of this
phase is lighter than that of the
other two phase), the N cable
of UPS is connected to utility
neutral cable N, the UPS-GND
is connected to the grounding
club.
15. If the model of the unit you purchased is 110V input, please connect
UPS-L cable into line, connect N cable into neutral cable, and connect
UPS-GND cable to grounding club.
Please note that this equipment is single phase 220V or 110V, do
not connect to 3 phase 380V.
4.2 Output
1. Please refer to output installation table 2 when installing.
2. Position and way of connection, refer to figure 15.

3. Output power cable should be sized according to UPS size, do not use
undersized cabling. Please refer to Table 2

4. Avoid short-circuit and overload.
5. The comparison between output current rating and output cable size is
listed in Table 2.
6. The ground to this unit only acts as reference point, if the grounding is
bad, that may cause disturbance and false management, and affect UPS
performance. Speak to professional personnel for assistance

immediately.
7. Use a good grounding system.
8. Try to make the ground close to the connecting point of the grounding
club or origination point in the switchboard. Please refer to figure 16.
* Please install wiring according to input voltage
Contact an electrician or our service department if there is problem with
the installation.
