2.1 Environmental Requirements:
¾Ambient temperature should be in range of-10 ºC－40 ºC.
¾Please avoid putting inverter in a high temperature and moist location.
The humidity is less than 90% and non-condensing.
¾Avoid sunshine directly.
¾Keep away from combustible, explosive material and caustic gas or
liquid.
¾No dust, floating fiber and metal particles.
¾It must be installed in a firm and no vibration location.
¾Keep away from electromagnetic disturbance.
If users demand any special installation, please contract us firstly.
Installation space and distance of single inverter shows as fig 2-1-A that ambience should
be enough space. For several inverter installations, it should adopt guide clapboard to
ensure better cooling between each inverter shown as fig 2-1-B.
WARNING
1.Refer t o the inst ruction manual before inst allation
3.Donot remo ve any cover while applying power
andat least 10mi n. after disconnecting power.

3.1 Precautions
（1）Install a middle breaker between inverter and power supply avoiding enlarging
accident.
（2）For reducing electromagnetic interface (EMI), please connect surge absorber to
coil of electromagnetic contactors, relays etc.
（3）Freq setting terminal AI, instrument circuit（AO）etc., these analog signals wire
should be over 0.3mm² shield wire. Shield layer is connected with ground terminal CM
less than 30m.
（4）Wiring of relay input and output loop (X1 ~ X3) should choose over 0.75mm²
intertwist or shield wire. Shield layer should be connected to control terminal CM less than
50m.
（5）Separate control wire from main loop wire, parallel wiring should be part over
10cm, and across wiring should be vertical.
（6）Wire of Inverter and motor should be less than 30m. When it is over 30m, it
should decrease inverter carrier wave freq properly.
（7）All down-lead should be tightened with terminals to ensure well-contact.
（8）Compressive resistance of all down-lead should match with inverter volt.

Power
Please follow this manual for appointed input power specification.
Air-breaker switch
1. When inverter is in maintenance or long-time nonuse, air-breaker switch isolates
inverter and power supply.
2. When inverter input side has failure of short circuit or power low-volt, air-breaker
switch can take protection.
Contactor
Control power-on and power-off of inverter and load motor.
AC reactor
1. Increase power factor；
2. Reduce power network harmonic wave input from inverter；
3. Weaken imbalance effect on three phase power volt.
Breaking resistor
In the situation of regenerative braking, avoiding bringing volt too high.

4.4 Inverter Simple Operation
4.4．1 Inverter initialization set
（1）Freq input channel selection（[F0.0]）
Inverter initialization set is different based on each model. Set this parameter as 0, inverter
freq is set by panel number.
（2）Operation input channel selection（[F0.2]）
Inverter initialization set is different based on each model. Set this parameter as [F0.2]
=###0, inverter stop and startup is controlled by the key of operation panel STOP

①Please wire as fig 4-2；
②Be sure correct wiring then power on. Inverter displays “P.oFF”, then “0”；
Be sure [F0.0] = 0③；
④Based on inverter nameplate data for applied motor, please set parameter [F0.12] and
[F0.13]；
⑤Press key to start inverter, and inverter outputs freq 0 and displays “0.0”；
⑥Press key for UP function to increase set freq. Inverter output freq increases and
motor rotate speed increases；
⑦Check motor running is normal or not. If any abnormal, please stop running immediately
and power-off. Then, check the reasons and run again；
Press key for DOWN function to decrease set freq⑧；
⑨Press key again to stop running and power-off.
Manufacture setting value of carrier wave freq is fixed between 1.5-12KHz. If
motor without load and under high carrier wave freq running, it may cause
slight shock. So, please decrease carrier wave freq value (parameter [F0.8]）.
