3. WIRING

(4) Grounding Method

:

Mount the braking resistor unit on a grounded metallic plate. When it can-
not 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 class 3 ground
(ground resistance: 100Ω or less.)

:

Use the sizes specified in “INTERNAL CONNECTION SPECIFI-
CATIONS” for grounding cables.

3.5 INTERCONNECTION

Figs. 14 to 20 show the interconnecting diagrams of the braking unit or braking re-
sistor 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 Brak-
ing Units.

If using another braking resistor instead of YASKAWA braking resis-
tor unit, be sure to protect by thermal overload relay.
