Chapter one Safety Requirement and Cautions
To ensure safety of your health, equipment and property, please read this
chapter carefully before use the frequency inverter and act in compliance with
the instructions while carrying, installing, debugging, running and
overhauling the frequency inverter.
1.1 Safety definition
Danger: it will cause danger of serious injuries and even death while operating
against the rules
Caution: it will cause danger of light injuries or equipment destruction while
operating against the rules
Note: some information is useful while operating and use frequency inverter.
1.2 Safety requirements and cautions
●Before installation
Danger
1. Only qualified personnel can operate the equipment. Before operating,
be sure to carefully read the manual about safety, installation,
operation and maintenance. The safe operation depends on the proper
processes of choosing models, carrying, installation, operation and
maintenance.
Danger
1. Don’t use the damaged or incomplete frequency inverters; Otherwise,
there is risk of injury.
●Installation

2
Danger
1. Please install the frequency inverter on metal or other nonflammable
material, and keep it away from the combustible material. Otherwise
there is danger of fire;
2. No unauthorized modification to the frequency inverter; Otherwise
there is danger of damaged.
3. Normal frequency inverter, which is not explosion-proof, can not be
installed where with explosive gas or dust; Otherwise there is
danger of explosion.
Attention
1. When two frequency inverters are installed in the same control cabinet,
pleas pay attention to the installing place to guarantee the effective
heat dissipation.
2. When carrying the frequency inverter，please support its bottom.
Wiring
Danger
1. Wire is connected only when the main circuit is cut off, otherwise
there is a danger of shock.
2. Wire is connected by professional person only. Otherwise there is a
danger of shock.
3. Earth must be reliable. Otherwise there is a danger of shock.
4. AC power supply should not be connected with output ports U, V, W;
Otherwise there is a danger of damage to frequency inverter.
5. No drop of bolt, spacer, metal stick, conducting wire or other things
into the inner of frequency inverter; Otherwise there is a danger of
fire or damage to frequency inverter.
Attention

3
1. If the damage to frequency inverter or other equipment is caused by
improper wiring and utilization or unauthorized alteration, the user
should shoulder all responsibilities.
2. Please make sure all wirings meet EMC requirement and satisfy safety
standard in the local area; Please refer to recommendations in this
manual or national standards of wire diameter to avoid accidents.
3. Please connect the braking resistance or braking unit according to the
wire diagram; Braking resistance can not be connected to the terminals
of DC bus P（+）、N（-）; Otherwise it will cause fire or damage to frequency
inverter.
4.Human body electrostatic would seriously damage internal MOS
transistor,etc. No touch the printed circuit boards, IGBT or other
internal devices without anti-static measures, otherwise it will cause
the malfunction of frequency inverter.
5. Please don't connet phase shifter capacitance or LC/RC noise filter
to the output circuit of frequency inverter; Otherwise it will damage
the frequency inverter.
6. Please don't connect the magnetic switch or magnetic contactor to the
output circuit of frequency inverter; When frequency inverter is in the
operation with load, magnetic switch or magnetic contactor can make
inverter overcurrent protection function act, that will damage frequency
inverter seriously.
7. Please don't disassemble the panel cover, it only needs to disassemble
the terminal cover when wiring.
8. It is forbidden to do any pressure test on frequency inverter;Otherwise
it will damage the frequency inverter.
●Before electrification
Danger

4
1. Please make sure that voltage grade of power supply is consistent with
frequency inverter's voltage and then check whether the wiring is correct
and firm, and whether there is short circuit in peripheral equipment's
circuit. Otherwise it will damage frequency inverter and other
equipments.
2. Before the frequency inverter is connected to the input power supply,
make sure that the cover has been fixed well. Otherwise it will cause
electric shock.
3. For the frequency inverters whose storage time is over 1 year, when
electrification, the voltage should be raised by booster from low to
high. Otherwise it will damage the frequency inverter.
Attention
1. Check all periphery fittings are wired properly according to the
handbook; Otherwise it will cause accidents.
● After electrification
Danger
1. After electrified, it is forbidden to open the cover, make wiring, and
check up; Otherwise, it will cause the danger of electric shock.
2.After electrified, it is forbidden to contact internal wiring board and
its parts. Otherwise it will cause the danger of electric shock.
3.Do not operate or touch frequency inverter with wet hand. Otherwise there
is dangers of damage to frequency inverter and electric shock.
Attention
1. Pleasea set the parameter of frequency inverter cautiously; Otherwise
it will damage equipment.
●Operation
Danger

5
1. Before running, please check and confirm the application range of the
machine and equipments once more; Otherwise it will cause accidents.
2. Please don't touch the cooling fan and braking resistance to check the
temperature; Otherwise there is a danger of getting burn.
3.Unprofessional workers are banned to check the signals in the running
stage; Otherwise it will cause injuries and damage the equipment.
Attention
1. Please don't turn off the equipment by switching off power; Please cut
off the power supply after the electric machine stops running; Otherwise
it will damage the frequency inverter.
2.Please avoid anything dropping into the equipment when the frequency
inverter is running; Otherwise it will cause electric shock..
●Maintenance
Danger
1. Please don't maintain and repair the equipment with electric; Otherwise
it will cause electric shock.
2. Before maintaining and repairing the frequency inverter, please make
sure the indicator lights of power supply have completely turned off;
Otherwise it may cause electric shock and damage the frequency inverter.
3. Persons who have not passed specialized train are not allowed to conduct
the frequency inverter maintenance; Otherwise it may cause electric
shock and damage the frequency inverter.
1.3 Cautions in utilization
1. The general motor running at a low speed decreases its lifelime for the
heat dissipation effect is quite bad. If low speed running needs to last
for a long time, the frequency inverter special-purpose motor should be
chosen or the load should be lightened.
2. When using the frequency inverter, the temperature of motor is a little

6
higher comparing to the power frequency operation. It is normal phenomena.
3. In application of AC60 series frequency inverter, you have to confirm
all machine insulation to prevent damage to the equipment. Moreover, when
the motor working in tough environment, please periodic inspect the
electrical insulation to ensure the safety of the system work.
4. If the motor adapter is not consistent with frequency inverter's rating
current ( The rating current of the motor is far smaller than that of
frequency inverter), please adjust the protective value to ensure safe
running.
5. In occasions such as load raising, usually there is negative torque and
frequency inverter breaks off for over-current or over-voltagte. In this
case, you should consider to choose matching brake unit.
6. Frequency inverter, in a certain output frequency range, can meet the
load equipment’mechanical resonance. To avoid it, you can set up jumping
frequency.
7. As output voltage of the inverter is pulse-wave type, if there is capacity
which can improve power factor or pressure-sensitive resistance which used
for thunder-proof in the voltage output side, the frequency inverter will
break off or its parts will be damaged, so it is necessary to dismantle
them. Moreover, it is proposed not install switch parts like air switch
and contactor (if it is necessary to install switch on output side, please
make sure the output electricity of frequency inverter is zero when the
switche is working)
8. At over 1,000 meters altitude, the inverter’s heat dissipation function
worsened due to the thin air, it is necessary to derate use.
9. The inverter output voltage is pulse wave type. If use digital multimeter
measurement, deviation of the reading will be great. And the deviation is
different by using different type of digital multimeter. Under normal
circumstances, while RMS 380V, digital multimeter reading is around 450V.
