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 Distance
Wiring distance between the braking resistor unit and braking unit or braking
unit and inverter must be provided as shown in Fig. 13. Make sure to bundle
the wires between the units.
