Observe the correct DC power supply connection, polarity and terminal positions.
3.2.2 Circuit Breakers, Fuses, Grounding and Power
ATTENTION!
Use proper cable lugs for the power and grounding connection cables. Refer
to
for recommended wiring, circuit breakers and fuses.
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.
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
are guiding values. Installation
conditions and the maximum permitted voltage drop must be considered for
the proper wiring sizing.
