Chapter 3: Installation and Wiring

3.1 Safety Precautions

This chapter explains the warnings for safe use and stable running of the product.

Cautions in use

●While install the inverter in the closed cabinet, please build in cooling fan, air-conditioner or

other cooling equipment to ensure the temperature at the air-in port below 40℃. So that the

inverter can work safely and reliably.

●While installing, please use cloth or paper cover the inverter to prevent metal dust, oil, water

and others.And remove it carefully after working.

● While operation, please follow the ESD regulations. Otherwise, the inverter may be

damaged.

● While multi inverters are installed in the same cabinet, enough space must be left for cooling

fan.

●Inverter can not work over rated range.Otherwise, the inverter may be damaged.

●While transporting the inverter, please hold the firm case. If only hold the pre-cover, there is

danger of inverter main body falling, injury or inverter damage.

Cautions in use motor

●Different motor has different max allowable running speed. Motor can not run over the max

allowable running speed.

●While inverter is running at low speed, the motor auto-cool effect is seriously worse. If motor

runs at low speed for long time, it will be damaged for overheat. If needed, please use special

motor for inverter.

●While constant speed machinery runs at inconstant speed, there maybe sympathetic vibration.

Please install vibration-proof rubber under motor rack or use jumping frequency control

function.

●While using frequency inverter or working frequency power supply to drive, the torque

characteristic 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 it

and choose the right frequency inverter. Moreover, please do switch the pole while the inverter

input current is 0. Otherwise it may bring inverter protection or damage.

●The rated current of diving motor is higher than that of standard motor, please confirm it and

choose the right inverter.

●While the wire between motor and inverter is long, the max torque of the motor will reduce for

voltage drop. So please use thick cable while the distance between the motor and the inverter

is long.

3.2 Treatment for Inverter after Longtime Store

If the inverter store time is over one year, you must pre-charge the aluminum capacitor in the inverter again and install

the inverter after the aluminum capacitor characteristic recovering. For the specific method, please follow the grads in

the chart below and give corresponding proportional voltage for every grad more than 30 mins while the inverter is

no-load.

If the input voltage of one grad is at the action critical point of contactor, fan or other equipment, please increase or

reduce the corresponding input voltage for the grad to avoid any component working under critical state.

AC70 VC CONTROL FREQUENCY INVERTER MANUAL INSTALLATION AND WIRING

Chart 3-1: treatment for inverter after longtime store

can not be installed in the same cabinet with inverter, installed at the air-in port of the inverter

is strictly prohibited.

Table 3-1:AC70 series inverter running environment condition

● In order to improve the product stability, pls do not use the inverter where temperature changes sharply. While

using in closed space such as control cabinet, please use cooling fan or air-condition to cool inverter to avoid

temperature over limit range. Please also prevent inverter from freeze, too low temperature may cause components

freeze fault.

3.4 EMI Protection

The inverter is designed to be used in industrial environment with strong electromagnetic interference. Generally

speaking, if the installation quality is good, it is ensured that the inverter can work safely without fault. Please install the

inverter according to the following rules to ensure stable running and avoid electromagnetic interference impact.

● Ensure that all equipments in the cabinet have been connected reliably to the common 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

case to the inverter earth terminal or the protective area of control system.

● Ensure that all equipments connected to the inverter have been reliably connected to the same earth net or Y-type

earth point with thick and short cable.

● The conductor has better to be flat and with multi core, what has lower resistance at high frequency.

●The cutting terminal should be as soigne as possible. Unshielded wire section must be as short as possible.

● In control cable wiring, it should be as far from the power supply cable and motor cable as possible. And

independent cable trough should be used. While the control cable must cross to the power supply cable or motor

cable, it should be 90º vertical cross.

● Ensure that the contactor in the cabinet has wave surge suppresser. Or‘R-C’damping circuit is connected to the

winding of AC contactor. Voltage dependent resistor corresponding to the winding voltage is used. And freewheel

diode or components such as voltage dependent resistor corresponding to the winding voltage are connected to DC

contactor. It is very important while contactor, controlled by output relay of inverter, acts frequently.

● Cable connected to motor should be shielded cable or armoured cable. The two barriers are earthed reliably by

cable grounding card.

● Build noise filters at the input side to reduce electromagnetic interference from other equipments at the power grid

side. The noise filter should be as close to the inverter power input terminal as possible. Meantime, the filter must

earth reliably as the inverter.

● Build noise filters at the output side to reduce radio interference and inductive disturbance. The noise filter must be

as close to the inverter output terminal as possible. Meantime, the filter must earth reliably as the inverter.

AC70 VC CONTROL FREQUENCY INVERTER MANUAL INSTALLATION AND WIRING

● Anytime, control circuit wire should be shielded cable.

● Add zero phase reactor in power supply wire near inverter input terminal and add zero phase reactor in the motor

wire near inverter output terminal to reduce electromagnetic interference to the inverter efficiently.

● Earthing Right and reliable earthing is the basic condition of safe and reliable running of the product. For right

earthing, please read the following notice carefully.

●In order to avoid electric shock, earthing cable should be the size as electric

equipment technique standard required and cable length should be as short as

possible. Otherwise, inverter leakage current will cause unstable potential of the

earthing terminal which is far from the earthing point, and electric shock accident will

happen frequently.

●Earth terminal must be earthing. Earth resistance must be below 10Ω. Otherwise,

there is danger of death.

● Please do not share earth cable with welder or other big current/pulse power

equipment. Otherwise, inverter will act abnormally.

●While multi inverters are used at the same time, please do not wind the earth wire to

loop-type. Otherwise, inverter will act abnormally.

Chart 3-4: multi AC70 series inverters united earthing

Chart 3-5:AC70 series inverter system earthing

Remark: motor must earth as close as possible. Motor case can not be connected to the inner earth terminal of the

inverter. It also can not share the earth net with the control system.

● Shield of inverter power cable, motor cable, control cable Cable

Shielding layer (reticulate/armoured) should be winded reliably by cable earth card and fix to inverter earth piece by bolt.

Please refer to the following chart.

AC70 VC CONTROL FREQUENCY INVERTER MANUAL INSTALLATION AND WIRING

Chart 3-6:Cable earth card for cables earthing

●Corresponding relationship between inverter/motor cable length and carrier frequency.

While cable distance between inverter and motor is long (especially low frequency output), cable voltage drop will make

motor torque reduce. Further more, cable HF leakage current will increase. Then inverter output current will increase,

that will cause inverter over-current trip. The current detection accuracy and running stability will be impacted. Please

follow as below table to adjust carrier frequency according to the cable length. While the cable distance is over 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 0.7~15kHz 0.7~8kHz 0.7~4kHz 0.7~2kHz

Dismantle and install tail-hood

Installation: First the tail-hood upwardly inclines around 15

degrees and inserts the top fixed flat into the fixed hole in the

front cover. Then slightly press the tail-hood downward. While

your hear "Ka", it means that the tail-hood is into the place.

Chart 3-15:AC70 series inverter tail-hood installation

Dismantlement: At the tail of the frequency inverter, there is a

special dismantlement hole design. Put your finger into the

hole, upwardly pull the cover with a little force until the buckle

between the tail-hood and the crust tear off, and then remove

the tail-hood down.

3.6 Electric Installation

This chapter explains the regulations that users have to obey to ensure safe use, best performance and reliable

running.

Safety precaution

● Must earth reliably while inverter is running. Otherwise there is danger of casualty and

unstable inverter performance.

● To ensure safe running, only trained professional person can do installation and wiring

job.

● No operation under power connected state. Otherwise there is danger of electric shock

even death.

● Before operation, please cut all related equipments power, ensure that the main circuit

DC current has dropped to safe range. And please operate after 5 mins.

● Control cable, power cable and motor cable must be separated. They can not be in the

same cable trough or cable rack.

● This equipment can only be used as the maker states. Please consult Veichi while using

in special case.

● No insulation test for the inverter or the related cable by HV insulation test equipment.

● If the inverter or the peripheral equipment (filer, reactor and etc) needs insulation test,

firstly 500V megohmmeter should be used to test the insulation resistance which should

not be lower than 4MΩ.
