Mounting the Instrument Main Unit
Provide an instrumented panel steel sheet of 1 to 10 mm thickness.
After opening the mounting hole on the panel, follow the procedures below to install
the controller:
1) Insert the controller into the opening from the front of the panel so that the
terminal board on the rear is at the far side.
2) Set the brackets in place on the top and bottom of the controller as shown in the figure
below, then tighten the screws of the brackets. Take care not to overtighten them.

•
m
Insert the controller
into the opening at
the front of the panel.
CAUTION
• Tighten the screws with appropriate tightening torque within 0.25 N•m.
Otherwise it may cause the case deformation or the bracket damage.
• Make sure that foreign materials do not enter the inside of the
instrument through the case’s slit holes.
