3.2.2 Circuit Breakers, Fuses, Grounding and Power

ATTENTION!
Use proper cable lugs for the power and grounding connection cables. Refer to
„
table B.1
Keep sensitive equipment and wiring at a minimum distance of 0.25 m (9.85 in) from
„
the inverter and from the cables connecting the inverter to the motor.
It is not recommended the use of mini circuit breakers (MDW), because of the
„
actuation level of the magnet.
ATTENTION!
Residual differential interrupter (DR):
When used in the inverter supply, it must have a pick-up current of 300 mA.
„
Depending on the installation conditions, such as motor cable length and type,
„
multi-motor drive, etc., the DR interrupter may trip. Check with the manufacturer
the most suitable type for operation with inverters.
NOTE!
The wire gauges listed in
maximum permitted voltage drop must be considered for the proper wiring sizing.
