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) EN500/EN600 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,

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

1 Safety information and use notice points

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

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.

3.3 Wiring notice points

⑴Assure power be cut off completely for above 10 minutes before

wiring, otherwise there is danger of getting electric shock.

⑵ Forbid connecting power wire to output U, V, W of the inverter.

⑶ If there is current leakage inside inverter, inverter and motor must be

earth grounding for safety assurance, please refer to clause 8 in Chapter

3.4.1 for grounding wiring.

⑷ Before shipment compression resistance test of the inverter is

Passed, so users should not conduct compression resistance test again.

⑸ Do not add absorbing capacitor or other resistance-capacitor

absorbing device between inverter and motor; also do not add

electromagnetic contact. If contactor and other switch component

needed to add, please make sure inverter suspended without output,

show as Fig.3-6

⑹ To provide inverter over-current protection in output side and

convenient maintenance under power off, it should be connected to

power source through air switch and contactor.

⑺ Control signal wire should select multicore stranded wire or

shielding wire. One end of the shielding layer hang in the air, and the

other end connect to inverter earth grounding terminal, connection wire

shorter than 20m.

3 Installation and wiring

⑴Before wiring, assure power supply is cut off completely for 10

minutes and all LED or LCD indicator light extinguished.

⑵ Before inverter internal wiring, confirm that DC volt. Between main

loop end P+ and P- fall down to below DC36V.

⑶ Wiring can only be done by professional person trained and qualified.

⑷ Before power on, check if voltage grade of the inverter is in line with

that of power supply volt., otherwise will cause personnel injured and

device damaged.
