  • Page 4: Notes For Operation

    NOTES FOR SAFE OPERATION Read this instruction manual thoroughly before installation, operation, maintenance or inspection of the braking unit and the braking resistor unit. In this manual, NOTES FOR SAFE OPERATION are classified as “WARNING” or “CAUTION.” WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury to personnel.
  • Page 6 WIRING WARNING (Ref. page) • Only commence wiring after verifying that the power sup- ply is turned OFF. Failure to observe this warning can result in an electrical shock or a fire. • High voltage exists at all terminals of braking unit and braking resistor unit.
  • Page 7 CAUTION (Ref. page) S Verify that the rated voltage of the braking unit and the braking resistor unit coincides with the AC power supply voltage. Failure to observe this caution can result in personal injury or a fire. S Do not perform a withstand voltage test of the braking unit and braking resistor unit.
  • Page 8 OPERATION WARNING (Ref. page) S Only turn ON the input power supply after replacing the front cover. Do not remove the cover while current is flowing. Failure to observe this warning can result in an electrical shock. CAUTION (Ref. page) S Never touch the heatsink or discharging resistor since the temperature is very high.
  • Page 10 CAUTION (Ref. page) S The control PC board employs CMOS ICs. Do not touch the CMOS elements. They are easily damaged by static electricity. S Do not connect or disconnect wires or connectors while power is applied to the circuit. Failure to observe this caution can result in personal injury.
