Precautions
■
Correct Use
Mounting
Make sure that the plate to which the D4CC is mounted is flat. If the
plate is warped or has protruding parts, the D4CC may not malfunc-
tion.
Mounting Holes
A maximum of 6 Switches may be group-mounted. In this case, pay
attention to the mounting direction so that the convex part of the
group-mounting guide on one Switch fits into the concave part of the
guide on the other Switch as shown in the figure below. For group
mounting, the mounting panel must have a thickness (t) of 6 mm min.
Group Mounting
Tightening Torque
Be sure to tighten each screw to the proper tightening torque as
shown in the table.
Note: By removing the two screws from the head, the head direction
can be rotated 180
°
. After changing the head direction, re-tight-
en to the torque specified above. Be careful not to allow any for-
eign substance to enter the Switch.
Plug Tightening
Connect the plug connector (B) to the connector threads of the
D4CC. Then firmly turn the plug connector by hand so that the con-
nector threaded portion (C) will be completely covered by the plug
connector (B) so that space (A) will be almost 0. Do not use any
tools, such as pliers, to tighten the plug connector, otherwise the plug
connector may become damaged. Make sure, however, that the plug
connector is tightened securely, otherwise the rated degree of pro-
tection of the D4CC may not be maintained. Furthermore, the plug
connector may be loosened by vibration.
