(3) Connection instructions
Keep the wires between the servo amplifier and the brake unit, and between the resistor unit and the
brake unit as short as possible. For wires longer than 5 m, twist the wires five times or more per meter.
The wires should not exceed 10 m even when the wires are twisted. If wires exceeding 5 m without
twisted or exceeding 10 m with or without twisted are used, the brake unit may malfunction.

POINT
Under tightening can cause a cable disconnection or malfunction. Over
tightening can cause a short circuit or malfunction due to damage to the screw
or the brake unit.
