Basic Configuration - Mitsubishi Electric FR-F500 Instruction Manual

1.2 Basic Configuration

1.2.1 Basic configuration
The following devices are required to operate the inverter. Proper peripheral devices must be selected and correct
connections made to ensure proper operation. Incorrect system configuration and connections can cause the
inverter to operate improperly, its life to be reduced considerably, and in the worst case, the inverter to be
damaged.
Please handle the inverter properly in accordance with the information in each section as well as the precautions
and instructions of this manual. (For connections of the peripheral devices, refer to the corresponding manuals.)

supply system (1000KVA or more and
wiring distance within 10m). Make selection
carefully.
• The inverter life is influenced by ambient
temperature. The ambient temperature
should be as low as possible within the
permissible range.
This must be noted especially when the
inverter is installed in an enclosure.

• Incorrect wiring might lead to inverter
damage. The control signal lines should
be kept away from the main circuit to
protect them from noise.
