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 SPECIFICA-

TIONS” for grounding cables.

3.5 INTERCONNECTION

Figs. 14 to 20 show the interconnecting diagrams of the braking unit or braking

resistor unit and VS-616G5.

Refer to Par. 3.3, “Wiring Precautions” for proper wiring in actual wiring design

and work.

Be sure to connect braking resistors or braking resistor units to the braking units.

Connect only braking resistors or Braking Resistor Units (LKEB-XXXX) to

Braking Units.

1. If using another braking resistor instead of YASKAWA braking

resistor unit, wiring sequence should shut off power to the drive

when a braking resistor Overload Relay Trip Contact (Thermal

Protector Contact) output is triggered.

2. Faulty wiring can result in fire. Make sure the interconnecting

diagrams are followed correctly.
