★

Wiring c an only be done after the mains input is cut off, otherwise there will be danger of electric

shock!

Only qualified and trained engi neer can perform the wiring, otherwise there will be danger of

el ectri c shock!

Grounding cable must be grounded, otherwise t here will be danger of electric shock or fire!

★

Please confirm the mains vol tage level is s ame with that of the inverter, ot herwi se the inverter

may be damaged!

Make sure the ratings of the driven motor are i n compliance with the inverter, otherwi se the

motor ma y be damaged or the inverter may be in protection status !

Do not confuse the input terminals with the output terminals (U, V, W), ot herwise the re will be

danger of damaging the inverter!

Brake resistor cannot be c onnected betw een the DC bus terminals (+) and (-), otherw ise fi re

may occ ur!

The brake resist or terminal is effective only for the inve rte r of 15kW or bel ow and has a bui lt-in brake

unit . Select the recommende d re sis tor with the cable length of less than 5m, otherwi se the inverter may

burn or be damaged.

D. Inverter output U, V and W:

Inverter output terminals cannot connect t o capacit ors or surge snub devices, otherwi se the inverter may

be in protecti ve stat us or damaged.

If the cables between the motor and t he inverter are too long, el ectrical res onance may occ ur due to the

distribut ed capacitance, which may result i n damaging the motor i nsul at ion or big l eakage current, so if

the cable length is longer t han 100m, AC reactor must be i nstal led.

2) Reducing the dis turbance to th e in ver ter fro m o the r equ ipme nt

The re lay, co ntactor or ele ctro nic -magnetic br aking dev ice wil l disturb t he inve rte r.

Tak e the following actions to solve this issue:

A) Ins tall surge sup pre ssing d evices to th e disturbing devic e

B) Ins tall filter t o the input of the inverter

C) Inv erte r's contro l ca bles shall be shie lde d a nd t he shielding layer shal l be gro unded

3) Met hod to redu ce the di sturbance from the i nve rter to the equip ment

Two k inds of noises , one is the ra diation from the inverte r it self, and a nother is the radiation from the

cable b etwee n the in ve rter and th e moto r. T hes e tw o k inds of ra diations induce the cables of th e

equ ipm en t and mak e th e equipme nt work a bno rmally. Follo wing m ethod can be use d:

A) If the mea sur ing me ters , ra dio equipment and sens ors and th eir signal cab les are installed in a

cabine t together with th e drive, thes e equip me nt c ables w ill be eas ily disturb ed. Take the actions

below to s olve the p roblem: The equipment and th e signal cable s s hou ld be a s far aw ay fro m the

inverter as possible; Si gna l ca ble s and power cabl es shall not be ro ute d in pa ral lel o r boun d together;

The signa l and p ower c ables should b e shie lde d; Install radio noise filter and lin ear noise filter a t

the input and output sides of the inve rte r

B) If the e xterna l equ ipme nt shar es a same AC supply wi th t he inve rte r, a nd the above cannot eliminate

the dis turban ce, the n the u ser should install a line ar filte r or a radio no ise filter.

C) Ground th e ex ter nal equ ipment an d e limina te the disturb ance of the le aka ge cur rent fro m t he

inverter's grounding ca ble .

The in ver ter has two ki nds of leakag e curre nt, one is the gro unding lea kage c urrent and anoth er is the

lea kage curre nt betw ee n the lines :

1) Grou nd ing leakage c urr ent:

The distributed capacitanc e exist s between the cables an d the g rou nd, and the bigger the c apa citanc e

and the bigger th e le akage curren t, s o th e moto r ca ble s should b e a s sh ort as pos sible. B esides , the

bigg er the ca rrier frequenc y is, the b igger the leakage cu rrent i s, so the us er c an also re duc e the c arr ier

wa ve f requency, but the motor noise ma y incre ase . In sta lling re actor c an also re duc e the leakage curren t.

The le aka ge cur rent is increas ed wit h th e incre ase of the circuit curren t, so the l eakage curren t is big if

the motor power is big.

2) Lea kage curre nt betw ee n lines:

The distributed capacitanc e exist s in the inver ter抯 o utput cables, and re son anc e may occur if high

fre que ncy ha rmo nic s e xist in the curren t, thus the lea kage c urre nt occu rs , which may result in the wrong

action of rela y.

The method to so lve this issue is to r edu ce the car rier fre que ncy or install the output re actor. I t is

rec ommende d to us e in ver ter抯 protection fun ction i nst ead of a th ermal rela y to pro te ct the motor before

using the inv erte r.

Note: Pay attention to the polarity of the dio de as shown in the figur e 3-8. Othe rwise if the digita l

output terminal has output, the DC24V pow er supply w ill be dama ged.

6. EMC Issue s

6 1 Influence of Harmonics

6. 2 EM I

1) The h igh frequency ha rmoni cs of m ains supply will influe nce the rectifying circuit of t he inverter.

The harmonic s will heat t he rec tifying circ uit and ev en dama ge th e circuit. So, it is recommended to

install the filt ering devic e in the envi ronment where the pow er qua lity i s poor.

Since the in verte r output has hig h freque ncy harmonics, the output cannot be ins talled with

ca pacitor or surge s uppre ssing devic es bec ause the cap acitor and s urge suppre ssing devic e may

re sonate the c ircuit and damage the e quipment.

1) Two kinds of EM I, one is the EMI around the inverter and distu rbs the inve rter. T his kind of E MI is

w eak, besides the in verte r has been designed with strong immunity. Another i s the E MI from the

inverter that m ay influence the equipment around the inverte r. The inve rter its elf is a disturbance

source b ecaus e it outputs PWM wave through high carrier frequency, so solving the EMI issue is

mainly to reduce the EMI of inverter.

M ethods:

A ) Inve rter an d oth er equipment shall be w ell grounde d and the gr ounding res istanc e sha ll be le ss tha n

5ohm.

B ) Inve rter's p ower cable s shall be ve rtical inste ad of paralle l with the c ontrol cable s.

C ) For the app lication with strong dis turba nce, the pow er ca bles from the motor to the inverter shall b e

shielded and the shi elding laye r shall be gr ounde d.

D ) The c ables of disturbe d equi pment shall be tw isted shielded ca bles and the shiel ding la yer s hall be

gr ounde d.
