A1-6
Motor Over Temperature Protection
Motor over temperature protection shall be provided in the end use application.
■ Field Wiring Terminals
All input and output field wiring terminals not located within the motor circuit shall be marked to indicate the
proper connections that are to be made to each terminal and indicate that copper conductors, rated 75°C
are to be used.
■ Inverter Short-Circuit Rating
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.DiJ2.lHp 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.
