Installation Of The Inverter - Mitsubishi Electric FR-A700 Installation Manualline

INSTALLATION OF THE INVERTER

AND INSTRUCTIONS
Installation of the inverter
•
Note - Some inverter models may be installed outside an enclosure. See Appendix 2 for details.
Installation on the enclosure
FR-A720-00900 or less
FR-A740-00440 or less
FR-A760-00330 or less
REMARKS
To use an enclosed brake resistor for the FR-A760-00061 or less, refer to page 8.
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.
