A-6
This inverter has undergone the UL short-circuit test, which certifies that during a short circuit in the power supply
the current flow will not rise above value. Please see electrical ratings for maximum voltage and table below for
current.
• The MCCB and breaker protection and fuse ratings (refer to the preceding table) shall be equal to or greater
than the short-circuit tolerance of the power supply being used.
• Suitable for use on a circuit capable of delivering not more than (A) RMS symmetrical amperes for (HP) HP in
240 / 480 V class drives motor overload protection.

Inverter Motor Overload Protection
Set parameter 02-01 (motor rated current) to the appropriate value to enable motor overload protection. The
internal motor overload protection is UL listed and in accordance with the NEC and CEC.

02-01 Motor Rated Current
Setting Range Model Dependent
Factory Default: Model Dependent
The motor rated current parameter (02-01) protects the motor. The motor protection parameter 08-05 is set as
factory default. Set 02-01 to the full load amps (FLA) as shown on the nameplate of the motor.
