Appendix 2 Instructions for UL and cUL compliance

(Conforming standard UL 508C, CSA C22.2 No.14)
(1) Installation
This inverter is a UL / cUL Listed, enclosed type device with a suitably rated enclosure.
Design an enclosure so that the inverter surrounding air temperature, humidity and atmosphere satisfy the
specifications.
(Refer to page 136.)
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.
Wiring protection
For installation in the United States, branch circuit protection must be provided in accordance with the National
Electrical Code and any applicable provincial codes.
For installation in Canada, branch circuit protection must be provided in accordance with the Canadian Electrical Code
and any applicable provincial codes.
Provide the appropriate UL and cUL listed Class RK5, Class T or Class L type fuse or UL489 molded case circuit
breaker (MCCB) that is suitable for branch circuit protection in accordance with the table below.
Note, the Class L fuses can be used if the applicable current rating is larger than 600 A.
