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
gurebelow,thentightenthescrewsofthebrackets.Takecarenottoovertighten
them.

(bottom mounting hardware)
Panel
Insert a screwdriver into the
brackets to tighten the screws.
Direction to insert the
controller
Appropriate
tightening torque:
0.25 N•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.
