(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 152.)
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, 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.
* Maximum allowable rating by US National Electrical Code.
