For a product to receive UL certification, all components inside that product must also receive UL certification.
UL Standards Compliance
This inverter is tested in accordance with UL standard UL508C and complies with UL requirements. To ensure
continued compliance when using this inverter in combination with other equipment, meet the following
conditions:
■
Installation Area
Do not install the inverter 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.
■
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 (HP) HP in
240 / 480 V class drives motor overload protection.
