Danger
Installing
1. Please install the drive on
fire-retardant material, reserve the
drive away from combustible
materials, otherwise, it would cause
fire alarm!
2.If more than two drives are parked
in the same cabinet, in order to the
cooling effect of Drive, please note
that installation position and refer to
chapter 3 which is mechanical and
electrical installation.
3. Don't allow Conductors and screws
to fall inside the drive, otherwise there
is a danger of damage.
Wiring
1. Only the electrical engineering
personnel shall wire the drive,
otherwise, there is electric shock
danger.
2. Between the drive and power must
have circuit a breaker, otherwise, it
would cause fire alarm!
3. Never wire the drive unless the
input AC supply is totally
disconnected, otherwise, there is
electric shock danger.
4. The drive must be properly earthed
to reduce electrical accident,
otherwise, there is electric shock
danger.
5. Don’s connect the input power
supply to output terminals U, V and
W, otherwise, it would cause the
damage of frequency inverter.
6. Wiring must accord with EMC
requirements and the region safety
standards. Please refer to the manual
that advised about using wire line
diameter. Otherwise accidents may
occur.
7. Braking resistance cannot be
directly connected into DC between
bus (+) and bus (-) terminals.
Otherwise there is a danger of fire.
