Panel Hole Dimensions
•
Panel hole dimensions are given below.
•
The recommended panel thicknesses are given below.
•
If outer surface treatment such as coating is performed for the
panel, the panel dimensions after outer surface treatment must
meet the specified panel dimensions.
•
The following figure gives pitch dimension A and pitch dimension
B between the centers of the mounting holes.
Dimension A
Note:
The minimum mounting pitch is based on three Contact Blocks
in stage 1 with one wire attached to each terminal.
If you attach two wires or link Units, determine the mounting
pitch based on the dimensions diagrams and ease of operation
and wiring.
Dimension A When Using Accessory
•
Dimension A is 50 mm minimum when a Standard Legend Plate
Frame is attached.
•
Dimension A is 51 mm minimum when a Large Legend Plate
Frame is attached.
•
Dimension A is 75 mm minimum when a Protective Cover is

Mounting the Operation Unit
•
Panel Hole of 22.3-mm Diameter
Insert the Operation Unit from the front of the panel, insert the Lock
Ring and Mounting Nut from the back of the panel, and tighten the
Mounting Nut. Before tightening, check that the rubber washer is
present between the Operation Unit and the panel.
•
Panel Hole of 25.5-mm Diameter
Do not use the Lock Ring, and tighten the Mounting Nut while
confirming that the projecting part (see following figure) on the
Mounting Nut is aligned with mounting hole. Before tightening,
check that the rubber washer is present between the Operation
Unit and the panel.
•
Align the Lock Ring with the slot on the case and insert it so that
the edge is flush with the panel.
Mounting the Contact Block to the Operation Unit
•
Insert the Operation Unit into the Mounting Collar, aligning the TOP
mark inscribed on the Operation Unit with the lever on the
Mounting Collar, and then turn the lever in the direction indicated
by the arrow in the following figure all of the way until it clicks into
