Wiring •Do not pull hard on the lead wire. In particular, never lift an Auto switch actuator by holding the lead wires. Otherwise damage to the internal parts can result, causing malfunction. •Avoid repeatedly bending or stretching the lead wire, or placing heavy load on them. Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or breakage of the wire.
