Handling
The bottom of the Switch at the cable outlet is resin-molded. Secure
the cable at a point 5 cm from the Switch bottom to prevent exertion
of excess force on the cable.
When bending the cable, provide a bending radius of 45 mm min. so
as not to damage the cable insulation or sheath. Excessive bending
may cause fire or leakage current.
Connections
• Be sure to connect a fuse with a breaking current 1.5 to 2 times
• When using the Limit Switch for the EN ratings, use the gI or gG 10-

larger than the rated current to the Limit Switch in series in order to
protect the Limit Switch from damage due to short-circuiting.
