WIRING

• Precautions for wiring

Pay attention to the

following

items

during

wiring

to prevent mistaken

wiring

and mistaken usages.

,------------

Precautions

for

wirlng-------------..

(1)

When the power supply is applied on the inverter

output

terminals

CU,

Vand

W), the inverter will be damaged. Never wire the power

supply

to these

terminals.

(2)

Use a shield or twisted wire for the wiring to the control circuit

terminal,

and separate the

wires

from

the

main

circuit

or power

distribution

circuit

(200V

relay

sequence

circuit, etc.).

(3)

Cover

the

slits

on the inverter so

that

the

wire

waste

does

not

enter

the

inverter

during

wiring.

(4)

Confirm

that

the

display

lamp

on the key pad has gone out before changing

the

wiring

after

operation,

and

wait

at

least

two

minutes

before

starting

the

wiring.

(It

takes

more

than

one

minutes

for

discharge

of

the

internal

capacitors

after

disconnecting

power

supply.
