Appendix-2 Instructions for UL
Recommended Input Fuse Selection
◆ Motor Overtemperature Protection
Motor overtemperature 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.
■ Drive Short-Circuit Rating
This 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.
• 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
