NOTE
Ratings shown above apply to 40°C Ambient temperature. For derating information, refer to section
The drive is protected against short-circuit from power output to protective earth for all rated cable lengths, cable sizes and cable types.
The maximum cable lengths stated here are based on hardware limitations and do NOT take into consideration any requirements
for compliance to any EMC standards. Please see section
4.4. EMC Compliant Installation
for further information.
The PWM output switching from any inverter when used with a long motor cable length can cause an increase in the voltage at the
motor terminals, depending on the motor cable length and inductance. The rise time and peak voltage can affect the service life of the
motor. Lafert Group recommend using an output choke for motor cable lengths of 50m or more to ensure good motor service life.
Supply and motor cable sizes should be dimensioned according to local codes or regulations in the country or area of installation.
For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 70°C, UL Class CC or Class J
Fuses.
