Appendix 2 Instructions for UL and cUL
(Standard to comply with: UL 508C, CSA C22.2 No. 274)
1. General precaution
CAUTION - Risk of Electric Shock -
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.
ATTENTION - Risque de choc électrique -
La durée de décharge du condensateur de bus est de 10 minutes. Avant de commencer le câblage ou l'inspection, mettez l'appareil
hors tension et attendez plus de 10 minutes.
2. Environment
Before installation, check that the environment meets following specifications.
Surrounding Air
Temperature*
Ambient humidity
Storage temperature
Ambience
Altitude, vibration
* Surrounding Air Temperature is a temperature measured at a measurement position in an enclosure. Ambient Temperature is a temperature outside an
enclosure.
3. Installation
The below types of inverter have been approved as products for use in enclosure and approval tests were conducted under the
following conditions. Design the enclosure so that the surrounding air temperature, humidity and ambience of the inverter will satisfy
the above specifications. (Refer to page 44)
Branch Circuit Protection
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in
accordance with the National Electrical Code for the U.S. or the Canadian Electrical Code for Canada and any additional codes. As
specified, UL Class T, Class J, Class CC fuses or any faster acting fuse with the appropriate rating or Listed UL 489 Molded Case
Circuit Breaker (MCCB), or Type E combination motor controller must be employed.
