3.2 Installation
CAUTION
The inverter is designed for indoor use. Do not operate this UPS in direct
sunlight, in contact with fluids, or where there is excessive dust or humidity.
Place batteries in sound ventilation environment.
Use insulated tools to reducethe risk of short-circuit when installing or working with
the inverter, the batteries, or other equipments attached to this unit.
Be sure that the ground terminal has been connected with the ground.
3.2.1 Installation information
Inspect whether the battery voltage and Mains voltage are correct or not.
Connect the inverter with batteries, utility power and loads. Be sure all wiring is
correct, terminals are screwed tightly and terminal cover is locked.
Open the battery breaker, press ON button, then the inverter starts up in 3
seconds, and then check if the load has problem (overload, short-circuit ect.). If it

~ - 6 - ~
does, check and correct until confirmingit is normal, and then connect to the utility
power.

2500 W / 3500 W inverter battery connection
(Note that the red cable is connected to the positive terminal, black cable is

~ - 7 - ~
connected to the negative terminal, and 2500 W battery cable is more than 35 mm2,
3500 W battery cable is more than 50 mm2)
4 Operations
CAUTION
Turn on the inverter in battery mode first. Be sure that the load has no problem
(overload, short-circuit ect.) before connecting to utility power.
4.1 Turn the inverter On / Off
Without connecting to utility power, press and hold “ON”button for 3 seconds,
release it until the buzzer beeps, the inverter starts up. In the process of the
inverter running, press and hold “OFF”button for 3 seconds, release it until the
buzzer beeps, the inverter is shut down.
When the inverter works in mains power / AC mode, press and hold “OFF”button for 3
seconds, release it until the buzzer beeps, the inverter goes to bypass mode.
When the inverter works in bypass mode, press and hold “ON”button for 3
seconds, release it until the buzzer beeps, the inverter goes to AC mode.
