PREFACE Braking resistor unit and braking unit are used to con-sume regenerative energy from motor in the braking resistor unit at deceleration and to improve the transis-tor inverter braking ability. Before using the braking resistor unit and braking unit, a thorough understanding of this manual is recom-mended. This instruction manual will be of great help for daily maintenance, inspection and troubleshoot-ing.
General Precautions S Some drawings in this manual are shown with the protective cover or shields removed, in order to describe with more clarity. Make sure all covers and shields are replaced before operating this product. S Since the drawings in this manual are represented examples, some are subject to differ from delivered products. S This manual may be modified when necessary because of improvement of the product, modification or changes in specifications.
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.
WIRING WARNING • Only commence wiring after verifying that the power supply is turned OFF. (Ref. page) 27 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. 27 Failure to observe this warning can result in an electrical shock. • Wiring should be performed only by qualified personnel. 27 Failure to observe this warning can result in an electrical shock or a fire.
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. 27 S Do not perform a withstand voltage test of the braking unit and braking resistor unit. It may cause semi−conductor elements to be damaged. 27 S Connect braking resistors, braking resistor units, and braking units as shown in the I/O wiring examples.
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. 41 CAUTION (Ref. page) S Never touch the heatsink or discharging resistor since the temperature is very high. Failure to observe this caution can result in harmful burns to the body. 41 S Do not check signals during operation. The machine or the inverter may be damaged.
CAUTION (Ref. page) S The control PC board employs CMOS ICs. Do not touch the CMOS elements. They are easily damaged by static electricity. 46 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. 46 OTHERS WARNING S Never modify the product. Failure to observe this warning can result in an electrical shock or personal injury and will invalidate the guarantee.
WARNING INDICATION A warning label is displayed on the front cover of the braking unit, as shown below. Follow these instructions when handling the braking unit and the braking resistor unit.

3.4 WIRING PRECAUTIONS (1) Wiring Leading-in Method Lead in the wire through the knockout hole on the unit bottom. Since the knockout hole is provided with a rubber bush, cut the rubber bush central crosswise with a blade and lead the wire through. (2) Separation from Signal Lines Since strong noise component is superimposed on the braking resistor unit and braking unit wiring, separate the units from signal lines which are weak against noise.
3 WIRING (4) Grounding Method • Mount the braking resistor unit on a grounded metallic plate. When it cannot be mounted on a grounded metallic plate, pull out the lead wire from the mounting screw section to ground. • Braking unit grounding terminal must be provided with the ground resistance of 100Ω or less in 200V class ,or 10Ω or less in 400V class. • Use the sizes specified in “INTERNAL CONNECTION SPECIFICATIONS” for grounding cables. 3.5 INTERCONNECTION Figs.
