2. Safety Regulations
There are four kinds of symbols being related with cautions as following:
Danger: If user does not operate according to requirements, it will lead
to death, grievous bodily harm or severe property loss.
Warning: If user does not operate according to requirements, it will lead
to inverter injury or damage.
This s
y
mbol will offer some useful information.
This s
y
mbol will offer some items that need to be noticed in o
p
eration.
2.1 Installing
2.1.1. Do not install inverter on combustible material.
2.1.2. Do not install in explosive ambient.
2.1.3. Do not drop other material into inverter.
It is forbidden to disassemble and refit inverter.
2.2 Wiring
2.1.4. It must be operated by professional worker when wiring.
2.1.5. Please be sure to turn off the power supply at least 10 min before wiring.
2.1.6. Inverter and motor must be grounded correctly.
2.1.7. Be sure to wire and inspect after power-off at least10 minutes.
2.1.8. Electron components are sensitive about static electricity, so do not drop other
material into inverter or touch the main circuit.

E300 Series Mini-type Integrated Universal Inverter Manual

SUNFAR E300 SERIES
2.3 Maintenance
Do not touch radiator after power-off at least 10 minutes.
3. Attention Notes:
2.1.9. Be sure to install inverter in a well-ventilated ambient.
2.1.10. Motor temperature under inverter control will be higher than at main supply
control, which is normal phenomenon.
2.1.11. Normal 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.
2.1.12. When altitude is over 1000m, inverter will be valid to decrease rated current, and
rated current will decrease 10% when attitude is increased 1500m.
Be sure not to connect inverter output terminals with filter capacitors
or other surge absorbers.
4 Dispose:
When you dispose inverter and its parts, please pay attention to:
Capacitor: The capacitors in inverter may explode when they are burned.
Plastic: Poisonous gas may be generated when front panel is burned, please pay attention to
waste gas when plastic parts are burned.
Method: Please dispose inverter as industry waste.

Ambient temperature should be in range of-10 ºC－40 ºC.
Please avoid putting inverter in a high temperature and moist location.
The humidity is less than 90% and non-condensing.
Avoid sunshine directly.
Keep away from combustible, explosive material and caustic gas or
liquid.
No dust, floating fiber and metal particles.
It must be installed in a firm and no vibration location.
Keep away from electromagnetic disturbance.
If users demand any special installation, please contact us firstly.
Installation space and distance of one inverter shows as fig 2-1-A that space should be enough.
For several inverters installation, it should adopt guide clapboard to ensure better cooling
between each inverter shown as fig 2-1-B.

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.
Inverter output terminal U、V、W should not add absorber capacitor or other
RC absorber shown as fi

3.2 Wiring of External Components
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. Recommended
