SUNFAR E300 SERIES

2.1 Installing
Do not install inverter on combustible material.

Do not install in the explosive ambient.

Do not drop other material into the inverter.

It is forbidden to disassemble and refit inverter.

2.2 Wiring

2.2.1. It must be operated by professional worker when wiring.

2.2.2. Please be sure to turn off the power supply at least 10 min before wiring.

2.2.3. Inverter and motor must be grounded correctly.

2.2.4. Be sure to wire and inspect after power-off at least10 minutes.

2.2.5. Electron components are sensitive about static electricity, so do not drop other
material in inverter or touch the main circuit.

It is forbidden to connect AC power supply with the U, V
and W out

ut terminals directly.

2.3 Maintenance

o not touch the radiator after power-off at least 10 minutes.

2. The earth terminal of inverter must be connected to ground reliably.

3. Attention Notes:

3.1. Be sure to install inverter in a well-ventilated ambient.

3.2. Motor temperature at inverter control will be higher than at main supply control,

which is normal phenomenon.

3.3. Ordinary motor cannot run at low speed for a long time, so user should select

special motor for inverter or reduce motor load under low speed.

3.4. When the altitude is over 1000m, inverter will be valid to decrease rated current,

and rated current will decrease 10% when attitude is increased 1500m.

e sure not to connec

¾ Ambient temperature should be in range of-10 ºC－40 ºC.
¾ Please avoid putting inverter in a high temperature and moist location.

The humidity is less than 90% and non-condensing.

¾ Avoid sunshine directly.
¾ Keep away from combustible, explosive material and caustic gas or

liquid.

¾ No dust, floating fiber and metal particles.
¾ It must be installed in a firm and no vibration location.
¾ Keep 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.

3 WIRING

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.

¾ Inverter output terminal U、V、W should not add absorber capacitor or other

RC absorber shown as fig.3-1.

 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.
