Installation

Mounting to the Panel

Mounting the Operation Unit on the Panel

Insert the Operation Unit (Pushbutton, etc.) from the front surface of

the panel, insert the Lock Ring and the mounting nut from the termi-

nal side, then tighten the nut. Before tightening, check that the rub-

ber washer is present between the Pushbutton Unit and the panel.

When using a Legend Plate Frame, put one rubber washer each

between the Legend Plate Frame and the panel and between the

Operation Unit and the Legend Plate Frame. (One rubber washer will

be provided when one Legend Plate Frame is ordered.)

Align the Lock Ring with the groove in the casing, then insert the

Lock Ring so that its edge is located on the panel side.

Tighten the mounting nut at a torque of 0.98 to 1.96 N·m.

When using a Lock Ring, replace with the supplied Lock Ring, insert

the projecting part into the lock slot, and then tighten the mounting

nut.

When the panel cutout dimension is 25 dia., remove the supplied

rubber washer and mount the 25-dia. Ring as shown below. (Since

the A22Z-R25 is not attached to the main body, order separately.)

Mounting the Switch on the Pushbutton Unit

Insert the Pushbutton Unit into the Switch Unit, aligning the arrow

mark inscribed on the Case with the lever on the Switch Blocks, then

move the lever in the direction indicated by the arrow in the following

figure.

Removing the Switch

Move the lever in the direction indicated by the arrow in the following

figure, then pull the Pushbutton Unit or the Switch Blocks.

Since the lever has a hole with an inside diameter of 6.5 mm, the

lever can be moved in the specified direction by inserting a screw-

driver into the hole and then moving the screwdriver.
