About Radio Nolse

The inverter output and input circuits (main circuits) contain high frequency harmonics that may cause interference with communication equipment

(AM

so,

use of a noise filter FR-BIF (only for input circuit) or a line noise filter FR-BLF help to reduce the effects of noise. Please contact your mitsubishi supplier for additional information.

WIRING

Wlrlng

When wiring the inverter, pay attention

-

Wiring

(1)

Do

not connect power supply to the output terminals (u,v,w), because such miswiring causes dam-

aae to the inverter.

(2)

Connect nothing across terminals P and (option). Never short-circuit these terminals.

(3)

Use sleeved, shoulderless terminals for the terminals for power supply and motor.

(4)

Common terminals

Do

other.

(5)

Use shielded or twisted cables for wires connecting the control circuit terminals, and keep suffi-

cient distance from the main or high voltage circuits (e.g.,
