NEMA
Rating TheMMI-2XXSeriesfrontbezelisNEMA4rated.When installed properly in a NEMA 4 panel, the NEMA 4 rating of
the panel will not be compromised. This means that fluids will
notenterthe panelduringwashdowns.
Electrical
Environment TheDC poweredMMISeries hasbeentestedtoconform to EuropeanCE requirements.This meansthat theMMI circuitry
is designed to resist the effects of electrical noise. This does
notguarantee noiseimmunity insevere cases. Properwire

Panel
Details
5.1"
(129mm)
The MMI can be mounted into panels with a depth of
3"(76mm). It is recommended that the MMI be mounted
on the front panel of a steel enclosure, through a
7.1"(180mm) X 5.1"(129mm)opening.Allowaclearance
of 1"(25mm) on each side of the cutout for clip mounting
hardware.Allowclearancefor cableconnectionstothe
bottomofthe unit.Clearance mayvary accordingto cable
type used. Typically, plan a clearance to accommodate at
least 3"(76mm) below the cutout.

Mounting
Putthe MMIthroughthe panel cut out. Insert the clamps into the case. Pull back on the clips until they seat into the retaining slots. Tighten
clamping screws to 3 in.lb. of torque in an even pattern until
the MMI is secured in the panel.
NEMA-4
Mounting Slide the gasket over the case so that it rests behind the BezelFrame.Continuewithstandardmountingasdescribed
above.Avoidovertightening.
Specifications Note: To seal to NEMA-4 specifications, supplied gasket must
beusedand panelcannot flexmore than0.010".
When a gasket is used, the gasket may be sealed to the
caseusing anadhesivetomaintainNEMA-4 rating.
• The MMI is to be used indoors as a built-in interface. Make sure that
the unit is installed correctly and that the operating limits are followed
(SeeSpecifications).
• Do not operate the MMI in areas subject to explosion hazards due to
flammablegases,vaporsordusts.
•TheMMI shouldnotbeinstalledwherefasttemperaturevariationsand/
or high humidity are present. This will cause condensation of water in the
device.
