NOTE
Ratings shown above apply to 40°C Ambient temperature. For derating information, refer to section 10.4.1. Derating for Ambient
The drive is protected against short-circuit from power output to protective earth for all rated cable lengths, cable sizes and cable types.
3 phase drive can be connected to single phase supply when the output current is 50% derated.
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 4.13. EMC Compliant Installation for further information.
The maximum motor cable length stated applies to using a shielded motor cable. When using an unshielded cable, the maximum
cable length limit may be increased by 50%. When using the Invertek Drives recommended output choke, the maximum cable
length may be increased by 100%.
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. Invertek Drives recommend using an output choke for motor cable lengths of 50m or more to ensure good motor service life.
For IP20 Frame Size 8 the Vector Speed and Torque control modes may not operate correctly with long motor cables and output filters.
It is recommended to operate in V/F mode only for cable lengths exceeding 50m.
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
(exception: Eaton Bussmann FWP series must be used for size 6A & 6B IP20 models).
