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.
