1.Caution EM8 User's Manual

1. Caution

To ensure that you're personal, equipment and property safety, in use before frequency inverter, please be

sure to read this chapter content, and comply with in the later carry, installation, running, debugging and

maintenance, running process.

Warning

●This symbol can lead to death, serious injury or heavy losses of property.

Caution

●This symbol can lead to body moderate damage or minor injuries, equipment damage.

1.1 Safety caution clause

1.1.1 To get the product's confirmation

Caution:

●The damaged and lack of parts of the frequency inverter, do not install. Or you risk of injury.

1.1.2 Installation

Caution

●When carrying, please take the bottom of inverter, otherwise the inverter body may lose and hurt your

foot.

●Please install in metal materials plate burning not easily. If installed near flammable materials, there is

danger of fire.

1.1.3 Wiring

Warning

●Before wiring, please confirm the input power has cut off.

●Please let electrical engineering personnel wiring homework.

●Grounding terminals must be reliable grounding.

●Prohibit to input the power to output U, V, W terminal. Add in the output terminal voltage will lead

frequency inverter internal damage.

●The emergency stop terminal after wiring, please check its actions are effective. Or you risk of injury.

●Prohibit to touch output terminal, short connect output terminals and shell and between output terminals.

Caution

●Please confirm the input power voltage is the same as inverter rated voltage.

●Please do not do withstand voltage test for frequency inverter.

●please connect brake unit and resistor according to frequency inverter circuit diagram.

Otherwise you may cause the damage of the semiconductor components, etc.

1.1.4 Running, maintenance, inspection

Warning

●Prohibit to touch inverter input and output terminals

●Before power on, please install terminal house properly, before you take off terminal house, please make

sure power off.

●Amateur technicians, please do not for maintenance and inspection.

EM8 User's Manual 1.Caution

Caution

●The panel board, control circuit board, driving circuit boards installed the CMOS integrated circuit, when

using, please pay special attention, Directly with finger touch circuit boards, electrostatic induction it might

damage the circuit boards integrated chips.

●Power on, please do not change wiring or remove the terminal wiring. Have the risk of damage to

equipment.

1.2 Precaution of use

In using of frequency inverter , please pay attention to following clause.

1.2.1 Motor insulation confirmation

When use inverter, please make sure motor insulation to avoid damaging other equipment. In the motor

environment is poor, please routine check the insulation of the motor to ensure the safety of the system.

1.2.2 Negative torque load

Such as load of lift and elevator is negative torque load, the system will feedback current to inverter, so

please consider to match optional braking resistor.

1.2.3 Mechanical resonance of load equipment

Inverter in certain output frequency range, may meet load mechanical resonance, must be set to avoid

jumping through this frequency.

1.2.4 The capacitor and piezoresistor of improving power factor of electricity

As the inverter output voltage is pulse wave, so the output side cannot connect capacitor and piezoresistor,

which will damage inverter, please take off. At same time, please do not add air switch and contactor on

output of inverter. For 1-1 diagram, (if you must add switch device, please make sure the inverter no output

current, and then you can take on-off switch).

Diagram 1-1:Prohibit to connect capacitor on output of inverter

1.2.5 To drop down KW because of basic frequency setting

When basic frequency setting is lower than rated frequency, please drop down the KW of matched motor in

avoiding motor overheat burnt.

1.2.6 Running upper 50Hz

If inverter output is upper 50Hz, except consider motor vibration, noise, please consider the rated speed of

your motor avoiding damaging motor.

1.2.7 Electronic thermal protection of motor

When properly matched motor, inverter has thermal protection for motor. If inverter is not proper

matched with motor, please adjust relative parameter to protect motor.

1.2.8 To drop down KW because of altitude

When the altitude is higher than 1000m, the inverter must be drop down to match motor because of thin air

poor the cooling effect. As diagram 1-2 is the relationship curve of inverter rated current and altitude.

1.Caution EM8 User's Manual

Diagram 1-2: The curve relationship of output current and altitude

1.2.9About IP

Our inverter is IP20, you can add cabinet to improve its protection level.

1.3 End of life caution

When you end of inverter life:

The capacitor of main circuit and board can not burn, it will explode; Plastic house cannot burn, it will emit

toxic gas, please deal with it as industrial refuse.
