1 Safety information and use notice points

To make ensure personal & equipment safety, this chapter must be read

carefully before the inverter come into use.

1.1 Safety precautions

There are three kinds of safety warnings in this manual as below：

Symbol Symbol description

It may cause human death, serious injury or heavy property loss

with wrong operation.

It may result body or device damage with wrong and timeless

precautions under operation.

Should pay extra cautions when inverter in use under this

symbol

Note

1 Safety information and use notice points

Forbid to cut off the power source directly when inverter under

running, acceleration or deceleration status. Power source could

cut off when inverter completely in halt and standby status.

Otherwise user should be responsible for inverter and device

dama

e and human in

(1) Forbid to connect AC power source to output terminal U,V,W,

otherwise it could cause inverter completely damage.

(2) Forbid to install inverter on flammable objects, otherwise it

may cause fire.

(3) Do not install inverter in a environment with explosive gas, it

may cause explosion.

(4) Bare connection terminal should be insulation treatment after

main loop connection, otherwise it may cause electric shock.

(5) Do not operate inverter with wet hands when inverter power

on, otherwise it may cause electric shock.

(6) Inverter earth terminal should be well grounding connection.

(7) Do not open the front cover for wiring when inverter power on.

Inverter wiring and check must handle after 10 minutes of

inverter power off.

(8) Wiring connection should handle by qualified person and not

allow to slip any conductive objects inside inverter, otherwise it

may cause a electric shock or inverter damage.

(9) when inverter stocked for more than 6 months, using voltage

regulator to boost voltage up and keep inverter in standy status

for 1 hour, otherwise it may cause electric shock and explosion.

(1) Forbid to connect control terminals except TA, TB, TC to AC

220V/380V signal, otherwise it may cause inverter completely

damage.

(2) Do not install and run inverter when inverter damage or spare

part less, otherwise it may cause fire or human injury.

(3) inverter should install in a place where can accept itself weight,

otherwise it may cause inverter drop down or belongings damage.

1 Safety information and use notice points

1.2 Application range

(1) This kind of inverter apply to 3 phase ac asynchronous motor only for general

industry.

(2) It should handle cautiously and consult with manufacturer when inverter apply

to high reliability required equipment which relevant to life, properties and

safety device.

(3) This kind of inverter is the general motor control device in industry. When

inverter apply to dangerous equipment, safeguard should be considerable in

case of inverter failure.

1.3 Use notice points

(1) EN630/EN650A series inverter belong to voltage type inverter, and it is

normal with up temperature, noise and vibration of motor increasing over

power frequency run slightly.

(2) It is required to match inverter with variable frequency motor running at low

speed with constant torque for long time. When match inverter with general

asynchronous motor running at low speed, it should take measures to make

motor heat dissipation or monitoring motor temperature in avoid of motor

flash.

(3) It is necessary to take measures in advance for the damage caused for the bad

lubrication of the reduction box and wheel gear mechanical devices running at

low speed for long time.

(4) It is necessary to assure at first that the use speed range of motor bearings and

mechanical devices, also the increasing of motor vibration and noise should be

considered, when motor run over rated frequency.

(5) It is necessary to select the suitable brake assembly for hoisting device and big

inertia load to make sure the normal work when inverter stripping from power

grid for the overcurrent or overvoltage failure.

(6) Inverter start and stop control through terminal or other normal command

channel, otherwise it may cause inverter damage via connecting inverter input

terminal to big current switch just like contactor direct to start and stop

inverter frequently.

(7) It is necessary to make sure inverter cut off from operation without output,

when inverter and motor connect through switch components just like

contactor etc. Otherwise it will cause inverter damage.

(8) When inverter output frequency within some range, it may meet mechanical

resonance point of load device, through setting jump frequency to avoid it.

(9) Checking power supply voltage within allowed working range before usage,

1 Safety information and use notice points

otherwise, it need to change voltage or custom special voltage inverter.

(10)When inverter usage site altitude over1000 meters，inverter should decrease

current to use, output current decrease about 10% of rated current per 1000

meters increase.

(11)Motor should do insulation check before first usage or reusage after lay aside

for long time. Checking method show as graph 1-1 below with 500V voltage

type megohm meter , insulation resistance should not smaller than 5 MΩ，

otherwise inverter maybe damaged.

(12)Forbid inverter output side to assemble capacitor to improve power factor or

anti-thunder dependent resistor etc, otherwise it may cause inverter fault trip

or component damage show as graph 1-2.

2 Inverter Type and Specification

2.1 Incoming inverter inspect

(1) Check if there is damage during transportation and inverter itself has damage

or fall-off parts.

(2) Check if parts presented in packing list are all ready.

(3) Please confirm nameplate data of the inverter is in line with your order

requirement.

Our product is guaranteed by strict quality system during manufacturing,

packing, transportation etc., please contact our company or local agent rapidly
