2.1 Mounting Instructions
2.1.1 Location Considerations.
Care should be taken when locating equipment behind the
MMI to ensure that AC power wiring, PLC output modules,
contactors, starters, relays, and any other source of
electrical interference are located away from the back of
the unit.
Particular note should be taken to the position of variable
speed drives and switching power supplies. Their input
and load cables should be screened to a central star earth
point.
2.1.2 Making a NEMA-4 Mounting.

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. Allow a clearance
of 1"(25mm) on each side of the cutout for clip mounting
hardware. Allow clearance for cable connections to the
bottom of the unit. Clearance may vary according to cable
type used. Typically, plan a clearance to accommodate at
least 3"(76mm) below the cutout.
