Safety Precautions
Upon unpacking, please confirm that: Check whether the model and the rated values on the nameplate of the inverter are in
accordance with your order. Check if there is any damage occurred during transportation; pleases contact us or the distrib-
utor if you find any missing or damage of the products.
In order to use this product correctly, the user who uses the product for the first time must read this manual carefully and
pay close attention to the safety precautions.
Please keep this manual properly, hand it to the terminal user and lay it on the place where the operators can read it easily.
Confirmations Upon Delivery
Notice
1．Never install an inverter that is damaged or missing components. Doing so can result in injury.
Installation
Notice
1. Always hold the bottom of the inverter when carrying it. If the inverter is held by the front cover, the main body
of the inverter may fall, possible resulting in injury.
2. Attach the inverter to metal or other noncombustible materials. Fire can result if the inverter is attached to a
combustible material.
3. Install a cooling fan or other cooling device when installing more than one inverter in the same enclosure so that
the temperature of the air entering the inverters is below 45℃. Overheating can result in fires or other accidents.
Wiring
Danger
1. Always turn off the input power supply before wiring. Otherwise, an electric shock or fire may occur.
2. Wiring must be operated by an authorized person qualified in electrical work. Otherwise, an electric shock or
fire may occur.
3. Make sure to ground the ground terminals. Otherwise, an electric shock or fire may occur.
4. Always check the operation of any emergency stop circuits after they are wired. Otherwise, possibly result in
injury ( user responsibility for the wiring).
5. Never touch the output terminal directly by your hands or let the output terminals to come into contact with the
inverter case. Never short the output terminals. Otherwise, an electric short or ground short may occur.
6. Never touch the internal circuit or the zero-component until power off and the charge indicator is off as
there may still be high voltage inside theAC motor dirver.
Notice
◎Safty Precautions ◎

VB5N series inverter
3
1．Confirm that the voltage of the main AC power supply satisfies the rated voltage of the Inverter. Injury and fire
may occur if the voltage is not right.
2．Do not perform voltage withstand tests on the Inverter. Otherwise, semiconductor elements and other devices
can be damaged.
3．Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the I/O wiring examples.
Otherwise, a fire may occur.
4. Tighten all terminal screws to the specified tightening torque.
Otherwise, a fire may occur.
5. Do not connect AC power to output terminals U, V, and W.
The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.
6. Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.The Inverter may be
damaged or internal parts burnt if these devices are connected.
7. Do not connect electromagnetism switch, electromagnetism contactor to output circuit. When the inverter is
running with load, the electromagnetism switch and electromagnetism contactor will generate inrush current
which will cause inverter’s over current protection.
8. Do not disassemble the whole front cover as disassembling the top front while wiring is ok. Otherwise, inverter
internal parts may be damaged.
Maintenance and Inspection
Danger
1．Do not touch the inverter terminals, as they may carry high voltage.
Otherwise, an electric short may occur.
2．Make sure to have protective cover .Always have the protective cover in place when power is being supplied to
the Inverter. When attaching the cover, please with the power turns off.
Otherwise, an electric short may occur.
3．Maintenance, inspection, must be performed only by authorized personnel.
Otherwise, an electric short may occur.
Notice
1. A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully. The CMOS IC can
be destroyed by static electricity if touched directly.
2．Do not change the wiring, or remove connectors or the Digital Operator, during operation.
Otherwise, The devices may be damaged.
Constant torque low speed running
When the inverter outputs to a common motor at low speed for a long term, the output rated torque should be derated due
to the worsening radiating effect. If low speed constant torque long term running is required, then a special variable fre-
quency motor is needed.
Motor insulation
When using the V5/F5 series inverter, make sure to confirm the insulation of the motor which will be used to avoid device
damage. Besides, do the periodic check for the insulation condition of the motor located in the bad environment to guaran-
tee the system can operate safely.
Negative torque load
If in the case of improving load, negative torque may occur. Braking units should be connected with the inverter, or over
current and over voltage fault may happen.
◎Usage Precautions ◎

VB5N series inverter

Mechanical resonance point of load
The inverter may encounter the mechanical resonance point of load within certain output frequency range. Jump frequen-
cies have to be set to avoid it.
Capacitor and resistor
Because the inverter output pulse wave, capacitor and resistors shouldn't be connected with the output terminals of the in-
verter, or the inverter may trip or components may be damaged; Besides, don’t connect switch components such as air
switch and contactor with the output terminals is recommended, as shown in Fig.0-1(If switch components need to be
connected with the output terminals, make sure output current of the inverter is zero when switch is acting).
Fig.0-1 Capacitor is prohibited to be connected with
output terminals of inverter
Derate according to basic frequency setting
When the basic frequency is lower than the reference frequency, please consider duration for the motor so as to avoid mo-
tor’s damage caused by overheating.
Running at frequency above 50Hz
If running at frequency above 50Hz, besides the increment of vibration and noise, the ranges of running speed of motor
shaft and mechanical device have to be guaranteed. Be sure to make an enquiry first.
The electro-thermal protective value of motor
If the applicable motor is selected as per requirements, the inverter can perform the thermal protection to the motor. If the
ratings of applied motor are not in compliance with the inverter, be sure to adjust the protective value or adopt other pro-
tective measures to guarantee the safe running of motor.
Altitude and derate
When the altitude is higher than 1000m, the cooling effect of inverter is deteriorated because of the rareness of air, deration
must be considered, shown in Fig.0-2which indicates the relationship between the altitude and rated current of frequency
inverter.

About protection classes
The protection class of V5/F5 series inverter IP20 is reached in the case of status display unit or keyboard.
When you scrap the inverter, please pay attention to:
Explosion risk of capacitor: The capacitors in the main circuits may explode when they are burned.
Waste gas when plastic parts are burned: Poisonous gas may be generated when front panel is burned.
Dispose method: Please dispose as industrial rubbish.
