NOTE
• Ratings shown above apply to 40°C Ambient temperature. For derating information, refer to section Table
62: Derating for Ambient Temperature
• 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 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 Emerson
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. Emerson 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 use only with copper stranded conductors rated 75degC, UL Class CC or
Class J Fuses (exception: Eaton Bussmann FWP series must be used for size 6A & 6B IP20 models).
