(3) Connection of the brake unit (BU type)
Connect the BU type brake unit correctly as shown below. Incorrect connection will damage the inverter.
Remove jumpers across terminals HB-PC and TB-HC, then fit a jumper across terminals PC-TB.
Power
supply
Note: 1. For models 7.5K or less, remove the jumper across terminals PR-PX.
2. The wiring distance between the inverter, brake unit and discharge resistor should be within
2m (6.56 feet).
If twisted wires are used, the distance should be within 5m (16.40 feet).
3. When the transistor in the brake unit fails, the brake transistor bacomes extremely hot and it has
a chance to get fire. Therefore, install a magnetic contactor on the inverter's power supply side to
shut off current in case of failure.
4. When the power supply is 400V class, install a step-down transformer.
(4) Connection of the FR-HC type high power factor converter (FR-HC)
When connecting the high power factor converter (FR-HC) to suppress power supply harmonics, perform
wiring securely as shown below. Wrong connection will damage the high power factor converter and inverter.
After making sure that the wiring is correct, set "2" in Pr. 30 "regenerative function selection".
