Chapter 3 Installation and Wiring
3.1 Safety Precautions
This section specifies the various considerations necessary for reliable and safe operation of the product by users.
Inverter
●When the inverter is installed in closed cabinet, please ensure the temperature at the air-in
port below 40℃ by way of cooling fans or air conditioners and other cooling equipment to
ensure the safe and reliable operation of the inverter.
●When installing, please cover the inverter with cloth or paper to prevent metal dust, oil, water
and others. And remove these cover carefully after working.
● Please follow the ESD regulations when operating the inverter, otherwise, the inverter may
be damaged.
●If several inverters are installed in a cabinet, enough space must be set aside on the upper
part of the inverter in order to change the cooling fan.
●Inverter can’t work over rated range. Otherwise, the inverter may be damaged.
●When transporting the inverter, please hold the case firmly. There might be danger of inverter
main body falling, personnel injury or inverter damage if only holding the pre-cover.
Motor
●Different motor has different max allowable running speed. Motor can’t run over the max
allowable running speed.
●When inverter is running at low speed, the motor auto-cooling effect would seriously decrease.
If motor runs at low speed for long term, it will be damaged for overheating. If needed, please
use special motor for inverter.
●When constant speed machinery runs at inconstant speed, there might be sympathetic
vibration. Please install vibration-proof rubber under motor rack or use jumping frequency
control function.
●When using frequency inverter or working frequency power supply to drive, the torque
characteristics are different. Please do confirm the torque characteristic of the equipment
connected.
●The rated current of shift gear motor is different from that of standard motor. Please confirm
and choose the right frequency inverter. Moreover, please do switch the pole when the
inverter input current is 0. Otherwise, it may bring inverter damage.
●The rated current of diving motor is higher than that of standard motor, please confirm and
choose the right inverter.
●When the wiring distance between motor and inverter is far, the max torque of the motor
would reduce due to voltage drop. So please use cable thick enough when the distance
between the motor and the inverter is long.

3.2 Dealing Methods for Inverter after Long-term Storage
If the inverter storage time is over one year, the aluminum capacitor in the inverter must be pre-charged again and
make sure the aluminum capacitor characteristic recovered before installation. For specific method, please follow the
grads in the chart below and give more than 30 mins corresponding proportional voltage for every grad when the
inverter is no-load.
If the input voltage of one grad is at the critical point of contactor, fan or other equipments, please increase or reduce
the corresponding input voltage for the grad to avoid any related components working under critical state.
Chart 3-1: Dealing Methods for Inverter after Long-term Storage

3.4 EMI Protection
The designing features of inverter allow it to run with strong electromagnetic interference. Generally, if the quality of the
installation is good, the safe and trouble-free operation of the inverter can be guaranteed. Please implement installation
according to the following rules to ensure reliable and effective installation of inverters and avoiding electromagnetic
interference.
● Make sure that all equipments in the cabinet have been connected reliably to the public Y-type earth point or earth
bus with thick and short cable. The motor earth should be as close as possible. Please do not connect the motor
shell to earth terminal of the inverter or the protective area of control system.
● Make sure that all devices connected to the inverter are connected to the same earth net or Y-type earth point with
thick and short cable.
● It would be better for conductors to be flat and multi-core since they have lower impedance at high frequencies.
● When cutting off the tip, the cable should be as neat as possible to make sure that the unscreened wires are as short
as possible.
● Wiring of control cable should be away from the power supply cable and motor cable as far as possible; separate
trunk should be used and a 90º vertical cross must be used when the supply power cable and the motor cable
intersect.
● Make sure that the contactor should be installed in a cabinet with a surge suppressor. Alternatively, the AC contactor
coil is connected with 'R-C' damping circuit, using a coil voltage corresponding varistor; the DC contactor coil is
connected with 'flywheel' diodes or pressure thermistor type devices corresponding to the coil voltage, which is
particularly important when the contactor frequently operates and when contactor is controlled by the output relay of
the inverter.
● Cable connected to motor should be shielded cable or armored cable. The two barriers are earthed reliably by cable
AC100 HIGH-PERFORMANCE VC INVERTER MANUAL INSTALLATION AND WIRING
13
earthing card.
● Installation of 'Input Noise Filter' can reduce electromagnetic interference from other devices of the grid side, 'Input
Noise Filter' must be as close to the inverter input terminals, at the same time, the filter must earth reliably as the
inverter.
● Installation 'output side noise filter' can reduce interference from radio interference and induction noise. 'Output side
noise filter' must be as close to the inverter output terminals, at the same time, the filter must earth reliably as the
inverter.
● Control circuit cable should be shielded cables all the time;
● Adding zero phase reactor in power supply wire near inverter input terminal, adding zero phase reactor in the motor
wire near inverter output terminal and adding zero phase reactor in control wire near inverter control terminal to
efficiently reduce electromagnetic interference to the inverter.
● Earth
Right and reliable earth is the basic condition of safe and reliable running of the product. For right earth, please read the
following notice carefully.
●To avoid electric shock, earth cable should be the size as specified in the technical
standards for electrical equipment. And cable length should be as short as possible.
Otherwise, leakage current of inverter would cause unstable potential of the earth
terminal which is far from the earth point, and electric shock accident would happen
frequently.
● Be sure to ground the ground terminal. Grounding resistance 10Ω or less, it may
cause injury or death
●Earth terminal must be earth. Earth resistance must be below 10Ω. Otherwise, there
is danger of injury and death.
●Please do not share earth cable with welder or other big current/pulse power
equipment. Otherwise, inverter would act abnormally.
●When multi inverters are used at the same time, please do not wind the earth wire to
loop-type. Otherwise, inverter will act abnormally.

Chart 3-5：AC100 Series Inverter System Earth
Note: motor must earth as close as possible. Motor shell can’t be connected to the inner earth terminal of the inverter
and it can’t share the earth net with the control system either.
●Power cable, motor cable, control cable of inverter
Shielding layer (reticulate/armored) should be winded reliably by cable earth card and then fixed to inverter earth piece
by bolt. Please refer to the following chart.
Chart 3-6：Cable Earth Card for Cable Earth
● Correspondence between inverter and motor cable length and carrier frequency
When wiring distance between inverter and motor is long (especially low-frequency output), cable voltage drop will
cause the motor torque reduction. Moreover, high-frequency leakage current will increase, thereby causing an increase
of inverter output current, which would cause the inverter over current trip. And the current detection accuracy and
running stability would be seriously affected. Please refer to the cable length in the following table to adjust the carrier
frequency. When system requires the wiring distance to be more than 100m, please adopt distributed capacity reduce
measure (Such as “no metal conductor covers cable”, “wire each phase cable apart” and so on)
Cable length <20m 20~50m 50~100m >100m
Carrier frequency 0.6~16kHz 0.6~8kHz 0.6~4kHz 0.6~2kHz
