1.2 Safety attentions
Check after having received product
Warning
1. The damaged inverter or the inverter lack of parts can’t be installed.
Otherwise, danger of injury would be caused.
Installing
Warning
1. When carrying, please hold the bottom of inverter.
Only the panel is held, the inverter would fall off and such that you
would be injured.
2. Please install it on metallic plate not apt to be burned.
Install it on the flammable material, there would be fire caused.
3. If two or more inverters are installed in the same control cabinet,
please mount a fan and keep the air inlet temperature at below 40℃.
If too hot, there would be fire or other accidents caused.
Connection
Danger
1. Please make sure the input power supply has been cut off before
connecting.
Otherwise, danger of electric shock and fire would be caused.
2. Lease invites electric engineering technicians to connect the wire.
Otherwise, danger of electric shock and fire would be caused.
3. The earthing terminal must be earthed reliably.
(Class 380V: Suitable for earthing 3).
Danger of electric shock and fire would be caused.
4. After electrifying the emergency stop terminal, please check the
operation is available.
Otherwise, danger of injury would be caused. (The connection

CV3100 series and MINI series high performance general purpose inverter instruction manual
1-3
responsibility is borne by user)
5. Please never touch output terminal directly, connect inverter output
terminal to enclosure, or give the short connection among output
terminals.
Otherwise, danger of electric shock and short circuit would be caused.
Warning
1. Please make sure that AC main circuit power supply is identical with
the rated voltage of inverter.
Otherwise, danger of injury and fire would be caused.
2. Never conduct withstand voltage test for inverter.
Otherwise, damage of semiconducting elements would be caused.
3. Please connect the braking resistor or braking unit according to
diagram.
Otherwise, danger of fire would be caused
4. Please fasten the terminal by the screwdriver with specified torque.
Otherwise, danger of fire would be caused.
5. Never connect the input power line to terminals U, V, W.
Such that, the voltage is applied to output terminal, the inner of inverter
would be damaged.
6. Never connect the phase-shift capacitor and LC/RC noise filter to
output circuit.
Otherwise, the inverter inner would be damaged.
7. Never connect electromagnetic switch and electromagnetic contactor
to output circuit.
When When the inverter is running with the load, the surge current caused by
operation of electromagnetic switch and electromagnetic contactor would
cause over current protection circuit operation of inverter.

1-4
Maintaining and checking
Danger
1. Never touch the connection terminal of inverter as the terminal has
high voltage.
Otherwise, danger of electric shock would be caused.
2. Before electrifying, please install the terminal enclosure reliably, and
must cut off the power before disassembling the enclosure.
Otherwise, danger of electric shock would be caused.
3. Laypeople are not allowed to maintain and check.
Otherwise, danger of electric shock would be caused.
Warning
1. As CMOS integrated circuit is mounted on keyboard plate, control
circuit plate, driving circuit plate, please pay special attention when
using.
Once the circuit plate is touched by finger, the integrated chip on circuit
plate would be damaged for electrostatic induction.
2. In electrifying, never change the connecting wire or disassemble the
connecting wire of terminal.
In running, please never check the signal. Otherwise, the equipment
would be damaged.
1.3 Attentions of use
Please pay attention following points when using CV3100 series inverter.
(1) Constant-torque and low-speed running
In case that the inverter with common motor runs at low speed for a long time, the
life of motor would be affected for the poor heat radiation. So if it is needed low-speed
& constant-torque long time running, professional inverter must be selected.
(2) Confirmation of motor insulation
When using CV3100 series inverter with motor, please check up the insulation of
motor to protect equipment. In addition, if the motor is used in the harsh environment,
it is very necessary to check up the insulation of motor regularly, so as to protect the
safety of system.

CV3100 series and MINI series high performance general purpose inverter instruction manual
1-5
(3) Negative-torque load
The occasion that needs the load to be raised produces the negative torque usually,
the inverter would generate over current or over voltage fault, and so it would trip, in
case of this, a braking resistor shall be mounted.
(4) Mechanical resonance point of load device
In the certain output frequency range, the inverter is likely to meet the mechanical
resonance point of load device, if that, the jumping frequency must be set to avoid this
point.
(5) Capacitor or pressure sensitive element that improves power factor
If there is a capacitor or varistor for lightning protection that improves power
factor mounted on the output side, they shall be removed, otherwise, the inverter
would trip for fault or the parts would be damaged, because output voltage of inverter
is the type of impulse wave. In addition, on the output side, it is suggested that air
switch and contactor would not be installed either, shown as diagram 1-3. (If the
switch unit has to be mounted on the side of output, the output current of inverter must
be zero when the switch operates.)
Diagram 1-3 Inverter output side never mounted with a capacitor
(6) Run at over 50Hz.
If the inverter has to run at over 50Hz, the applicable speed range of motor
bearing and mechanical equipment must be guaranteed in addition to considering the
vibration and noise of motor, and please inquire before inverter runs.
(7) Electronic heat protection value of motor
When a motor chosen is applicable, the inverter can provide the motor with heat
protection. If the motor doesn’t match with the rated capacity of inverter, the
protection value must be adjusted or other protection measures must be taken, to
guarantee the motor runs safely.

(8) Altitude and derating use
If the inverter runs in area of over 1000m altitude, it must be derated by reason
that the heat radiation of inverter gets poor for rarefied air. Diagram 1-4 shows the
relation between rated current of inverter and altitude. If the installation site is higher
than 2000 m above sea level, the inverter will not be able to meet IEC61800-5-1 the
requirements of low voltage protection .
Diagram1-4 Relation between rated output current of inverter and altitude
(9) Protection degree
Protection degree IP 20 of CV3100 inverter is got in the state of use or keyboard
display.
1.4 Rejection attentions
Before scrapping the inverter, please pay attention following information:
When burning, the electrolytic capacitor of main circuit and electrolytic capacitor of printed
board are likely to explode, and the plastic part will produce noxious gas. Therefore, the
inverter shall be handled as the industrial rubbish.
