Installation
Note: Do not use the wall receptacle as the input power source for the 2/3KVA UPS, as
its rated current is less than the UPS’s maximum input current. Otherwise the receptacle
may be burned and destroyed.
4) Connect the input and output wires to the corresponding input and output terminals
according to the following diagram.
Note: you must make sure that the input and output wires and the input and output
terminals are connected tightly.
5) The protective earth ground wire refers to the wire connection between the
equipment which consumes electric equipment and the ground wire. The wire
diameter of protective earth ground wire should be at least as above mentioned for
each model and green wire or green wire with yellow ribbon wire is used.
6) After having completed the installation, make sure the wiring is correct.
7) Please install the leak current protective breaker at the output power distribution
panel of the UPS if necessary.
8) To connect the load with the UPS, please turn off all the loads first, then perform the
connection and finally turn on the loads one by one.
9) No matter the UPS is connected to the utility power or not, the output of the UPS
may have electricity. The parts inside the unit may still have hazardous voltage after
turning off the UPS. To make the UPS have no output, power off the UPS, and then
disconnect the utility power supply.
10) Suggest charging the batteries for 8 hours before use. After connection, turn the
input breaker in the “ON” position, the UPS will charge the batteries automatically.
You can also use the UPS immediately without charging the batteries first, but the
backup time may be less than the standard value.
11) If it is necessary to connect the inductance load such as a monitor or a laser printer
to the UPS, the start-up power should be used for calculating the capacity of the
UPS, as its start-up power consumption is too big when it is started.
