UL/CUL Mark
v UL Standards Compliance
This AC Drive is tested in accordance with UL standard UL508C and complies with UL requirements. To ensure
continued compliance when using this AC Drive in combination with other equipment, meet the following conditions:
■ Installation Area
Do not install the AC Drive to an area greater than pollution severity 2 (UL standard).
■ 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.
■ AC Drive Short-Circuit Rating
This AC Drive 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.
• Circuit protection must be installed before AC drive. See section 2.3 of the user manual for the appropriate circuit
breaker for your drive.
• 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.
Horse Power ( HP ) Current ( A ) Voltage ( V )
1 - 50 5,000 240 / 480
51 - 200 10,000 240 / 480
v AC Drive 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.
