Wiring - Mitsubishi Electric FR-E700EX Instruction Manual

Drive unit and peripheral devices
NOTE
 The life of the drive unit is influenced by surrounding air temperature. The surrounding air temperature should be as
low as possible within the permissible range. This must be noted especially when the drive unit is installed in an
enclosure. (Refer to page 7)
 Wrong wiring might lead to damage of the drive unit. The control signal lines must be kept fully away from the main
circuit to protect them from noise. (Refer to page 14)
 Do not install a power factor correction capacitor, surge suppressor or noise filter (capacitor) on the drive unit output
side. This will cause the drive unit to trip or the capacitor and surge suppressor to be damaged. If any of the above
devices are connected, immediately remove them.
 Electromagnetic wave interference
The input/output (main circuit) of the drive unit includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the drive unit. In this case, install the FR-BIF optional noise
filter (capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF noise filter (ferrite core) to minimize
interference. (Refer to page 36)
 Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.
 A PM motor cannot be driven by the commercial power supply.
 A PM motor is a magnet motor. High-voltage is generated at motor terminals while the motor is running even after the
drive unit power is turned OFF. Before closing the magnetic motor starter at the output side, make sure that the drive
unit power is ON and the motor is stopped.
 Do not use a magnetic contactor at the drive unit's output side.
