There is a small gap between an electric cable and inner wires. If waterproofing
of cable connections and exposed cable ends is not adequately done, capillary
phenomenon may cause water intrusion into the interior of an actuator, resulting
in corrosion of parts and components. To prevent malfunction of an actuator,
ensure to adequately waterproof all cable connections and exposed cable ends
(Fig.15).

Ensure to isolate open ends of unused cables and wires to eliminate concerns of
a short circuit and actuator malfunction.
① Electric wiring must be worked by the personnel who are officially qualified according
to relevant national standards, rules and/or regulations.
② Refer to the wiring diagram shown on a housing cover of an actuator for correct wiring.
③ Tightly bundle
cables in a cable sheath and
firmly cover them cable ends with a plastic
tape, after having applied some gap filler.
