Installation

Mounting to the Panel

(1) Preparing the Panel

(2) Matrix Mounting

• The panel dimensions are shown below.

• The panel thickness must be 1 to 5 mm.

• Always use a 25-mm-dia. Lock Ring for a 25-mm-dia. hole.

IP65 degree of protection will be lost if the 25-mm-dia. Lock Ring is not

used because of the larger size of a 25-mm-dia. hole.

• When painting or coating the panel, make sure that the specified panel

dimensions apply to the panel after painting or coating.

(3) Mounting the Operation Unit on the Panel

• Insert the Operation Unit from the front surface of the panel, insert the Lock

Ring and the mounting nut from the terminal side, then tighten the nut.

Before tightening, check that the rubber washer is present between the

Operation 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.

(4) Mounting the Switch on the Operation Unit

• Insert the Operation 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.

(5) Removing the Switch

• Move the lever in the direction indicated by the arrow in the following figure, then pull

the Operation 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 screwdriver into the hole and then moving the

screwdriver.
