Precautions
■ Precautions for Correct Use
Wiring
Wiring Procedure
1. Loosen the cover mounting screws and remove the cover.
2. Run the wiring through the rubber connector on the cover and
then press-fit the solderless terminals. (The following solderless
terminals are available.)
3. After inserting the solderless terminal into the Switch, tighten the
terminal screws securely.
4. Mount the cover. (Make sure that the rubber connector is securely
pressed into the cover slot.)
5. Tighten the three screws evenly. (The optimum tightening torque
for each screw is 0.49 to 0.59 N·m.)
Applicable Lead Wires
Note: Do not use wires containing silicone, otherwise a contact failure
may result.
Applicable Terminals
The following solderless terminals can be used.
(Do not use fork or any other type of terminals, otherwise an
accidental disconnection resulting in a ground fault may result.)
Appropriate Tightening Torque
If screws are too loose, they can lead to an early malfunction of the
Switch, so ensure that all screws are tightened using the correct
torque.
Note: In particular, when changing the direction of the Head, make
sure that all screws are tightened again to the correct torque.
Be careful not to allow any foreign substance to enter the
Switch.
