(3) Connection instructions
Keep the wires between the converter unit 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.
