(3) Wiring precautions
Use as short wires as possible between a converter unit and brake unit and between a resistor unit and
a brake unit. If using a wire of 5 m or longer, be sure to use a twist wire (with 5 or more twists in 1 m).
Make sure that a wire is 10 m or shorter even when it is a twisted wire. If a wire of 5 m or longer is not a
twisted wire, or if a wire is a twisted wire and longer than 10 m, a malfunction may occur to a brake unit.

POINT
Fix a screw tightly otherwise the wire may come off or a malfunction may occur.
Fixing a screw too tightly can damage the screw or brake unit, resulting in a
short circuit or malfunction.
Terminal block
Do wiring with the stripped cable twisted to prevent it from
becoming loose. Do not solder it.
