10.2. Input/Output Power and Current Ratings
The following tables provide the output current rating information for the various P2 models. Bardac always recommends that selection
of the correct drive is based upon the motor full load current at the incoming supply voltage.

NOTE
Ratings shown above apply to 40°C Ambient temperature. For derating information, refer to section 10.4.1. Derating for Ambient
Temperature.
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 Bardac 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. Bardac recommends using an output choke for motor cable lengths of 50m or more to ensure good motor service life.
For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 70°C, UL Class CC or Class J
Fuses.
