Appendix 3 Instructions For Ul And Cul Compliance - Mitsubishi Electric FR-A720-0.4K Instruction Manual

Appendix 3 Instructions for UL and cUL compliance

(Conforming standard UL 508C, CSA C22.2 No.14)
(1) General Precaution
The bus capacitor discharge time is 10 minutes. Before starting wiring or inspection, switch power off, wait for
more than 10 minutes, and check for residual voltage between terminal P/+ and N/- with a meter etc., to avoid a
hazard of electrical shock.
(2) Environment
Before installation, check that the environment meets following specifications.
Surrounding Air
Temperature *1
Ambient humidity
Storage temperature
Ambience
Altitude, vibration
*1 Surrounding Air Temperature is a temperature measured at a measurement position in an enclosure. Ambient Temperature is a temperature
outside an enclosure.
2
*2 2.9m/s or less for the 160K or higher
(3) Installation
This inverter is UL-listed as a product for use in an enclosure.
Design an enclosure so that the inverter surrounding air temperature, humidity and atmosphere satisfy the
specifications. (Refer to page 175.)
Wiring protection
For installation in the United States, Class RK5, Class J, Class CC, Class L, Class T or any faster acting fuses or UL
489 Molded Case Circuit Breaker (MCCB) must be provided, in accordance with the National Electrical Code and any
applicable local codes.
For installation in Canada, Class RK5, Class J, Class CC, Class L, Class T or any faster acting fuses or UL 489 Molded
Case Circuit Breaker (MCCB) must be provided, in accordance with the Canada Electrical Code and any applicable
provincial codes.
