(1) Preparing the Panel

(2) Mounting the Operation Unit on the Panel

• The panel dimensions are shown below.

• The panel thickness must be 1 to 5 mm.

• Always use a 25-mm-dia. A22Z-R25 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.

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

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

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

Operation Unit and the panel.

• 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 Ring.

(3) Mounting the Switch on the Operation Unit

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.
