■ Wiring
◎Ensure only qualified electrical engineering personnel for wiring work . Otherwise it
can cause an electrical shock or damage to the VFD.
◎Make sure VFD is isolated from power supply by the circuit breaker. Otherwise it may
cause electrical shock or a fire.
◎Make sure that the ground terminal is grounded correctly. Otherwise it may cause
an electrical shock.
◎Do not touch the main circuit terminals, and keep the wiring of VFD main terminals
from contacting to the enclosure, or it can cause electrical shock.
◎Terminals for brake resistor are (+) and PB. Do not wire to other terminals, otherwise
will cause a fire.
◎Before wiring, ensure the VFD’s rated input voltage and phases is compatible to the
input power source, or it can cause a fire or personal injury.
◎Never connect the AC power supply to output terminals U, V and W. Otherwise the
VFD will be damaged and the guarantee is voided.
◎Never carry out withstand voltage test to the VFD, for example by a megohm meter.
Otherwise it may cause damage to the VFD.
◎VFD’s main circuit wiring and control circuit wiring should be separated, or run
vertically from each other. Otherwise it may cause interference to the control signals.

■ Operating
◎It is only allowed to power on the VFD after the wirng is finished and its cover is
reinstalled. It is strictly prohibit to remove the cover of VFD while power is on, otherwise
it may cause electric shock.
◎Before programming a VFD with fault auto reset or restart option after power off, the
mechanical device need to be implemented with safety measures first, otherwise it can lead
to personal injury.
◎”STOP/RESET” key may become invalid as a result of some function setting. It is
recommended to install an independent emergency circuit breaker for the VFD control
system, otherwise it may result in personal injury.
◎When the power is on, the VFD’s terminals may have electricity also even if it is in stop
mode. Do not touch U, V, W terminals and motor connection terminals. Otherwise it may
cause an electrical shock.
◎Do not use a magnetic contactor to control the start and stop of the VFD. Otherwise it
may cause the VFD to be damaged.
◎Before starting, please make sure that the motor and mechanical device can be run with
the VFD’s accelerating time setting in their safe range. Otherwise may result in device
damage.
◎Do not touch the heat sink or braking resistor. Otherwise it may cause harmful burns to
the body.
◎Never modify the parameters casually in unnecessary conditions, as the VFD’s default
parameter setting has already meet the requirements of most mechanical devices. Even if
some devices have special requirements, it is only needed to modify some necessary
parameters. Otherwise, it may cause device damage by improper parameter modification.

Chapter 2 Installation and Wiring
2.1 Installation
2.1.1 Installation Environment
◎The ambient temperature exerts great influences on the service life of the VFDs
and is not allowed to exceed the specified temperature range (-10℃ to 40℃ ).
◎A VFD is easy to generate large amount of heat during operation. Thus VFDs
should be mounted vertically with screws on the surface of incombustible objects,
with sufficient spaces nearby for heat sinking.
◎VFDs should be mounted in the place without vibration or with vibration of less
than 0.6G, especially away from those kinds or machine such as punch.
◎The inverter should be mounted in locations away from direct sunlight, high
humidity, condensate, corrosive gas, explosive gas, oil dirt, dust, and metal powder
etc.

3. Eliminate the input current unbalance
caused by unbalance between the power
phases.
EMC Input
Filter
Input side of inverter
1. Reduce the external conduction and
radiation interference of inverter.
2. Decrease the conduction interference
flowing from the power end to the inverter and
improve the anti-interference capacity of the
inverter.
AC Reactor
at the
Output Side
Between inverter output side
and motor. Close to inverter.
The inverter output side generally has higher
harmonics. When the motor is far from
inverter, since there are many distributed
capacitors in the circuit, certain harmonics
may cause resonance in the circuit and bring
the following two impacts:
1. Degrade the motor insulation performance
and damage the motor when running for long
time.
2. Generate large leakage current and cause
frequent inverter protection.
Generally, installation of output AC reactor is
recommended when the distance between
inverter and motor exceeds 50m.

2.2.4 Precautions on Main Circuit Wiring
2.2.4.1 Terminals R, S and T
The wiring at the input side of inverter has no phase sequence requirement. When
input single-phase power, use terminal R and T.
2.2.4.2 DC Bus Terminals (+) and PB of Brake Resistor
The (+) terminal of DC bus have residual voltage right after power-off.
Wait until the CHARGE indicator is OFF and make sure that the voltage is less
than 36V before wiring. Otherwise it may cause electrical shock.
The cable length of brake resistor should be less than 5m.
2.2.4.3 Terminals U, V and W
Capacitor device or surge absorber cannot be connected to inverter output side by
terminals U, V and W. Otherwise, it may cause frequent inverter protection or
damage to inverter.
If motor cable is too long, it may generate electrical resonance easily due to the
impact of distributed capacitance and thus damage the motor insulation or generate
higher leakage current to cause inverter protection. When the length of motor cable
is longer than 50m, installing AC reactor at the output side is necessary.
2.2.4.4 Grounding Terminal
The terminal should be grounded reliably. The resistance value of grounding cable
should be less than 10Ω. Otherwise, it may cause fault or damage to the inverter.
Do not share the grounding terminal with zero line of power supply.

2.2.5 Precautions for Connecting Control Circuit Terminals
It is necessary to use shielded cable and twisted pair cable well-grounded (inverter
side). The cable should be more than 20cm away from power electricity cables and
conductors. Do not run the control cable paralleling to power electricity cables, try
vertically.
