Installation Notice
1
．
Before installing UPS, check if the feeding circuit of grid is clear, including contacts of all
the connection points as well as sockets are OK, so as to avoid open circuit or short circuit.
2
．
As for the input which is one-phase-three-lines system, do check whether the grounding is
good and ensure the voltage between zero line and grounding line is less than 5V. If the input
grounding line of mains supply is null, the voltage could be 100V. If the users’ load has strict
requirements on the voltage between the zero line and the grounding line of the power supply,
make sure the grounding of the mains supply is good so as to avoid unnecessary loss.

．
When you are installing UPS, do not connect the zero line, live line and grounding line of
Input and output of the UPS reversely or wrongly so as to avoid short circuit .Meanwhile,
Please check whether the voltage of the mains supply is normal.

．
If battery group installed for long back up time, do strictly accord with connection method
and sequence prescribed by the installation manual to wire and the wiring must be tie tightly.
Short-circuit to the polarities of battery and touch any two wiring terminals simultaneously or
bare ends of connecting wire are absolutely forbidden. Otherwise, it would result in battery
damage or even person injury. When battery group connected to UPS, check if the voltage of
battery group coincides with that demanded by UPS.
