1 INSTALLATION OF THE INVERTER AND INSTRUCTIONS
•
Installation of the inverter
•
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.
•
Environment
Before installation, check that the environment meets following specifications.
Note - Some inverter models may be installed outside an
enclosure. See Appendix 2 for details.
Installation on the enclosure
Fix six positions for the FR-F740-
04320 to 08660 and fix eight positions
for the FR-F740-09620 to 12120.

CAUTION
• Install the inverter on a non-combustible wall surface such as metal or concrete.
• Mount the inverter on a strong surface securely and vertically with bolts.
• Provide sufficient clearance distances away from other devices.
• WARNING: HEAT SINK SURFACE MAY BE HOT. TO REDUCE RISK OF BURN - DO NOT TOUCH.
