Where Used
The MMI8000 Series is designed for industrial environments. The operating temperature range is 32 to 113 °F (0
to 45 °C). It may not be suitable for using in certain outdoor applications. Please consult the factory for advised
usage in outdoor applications.
NEMA Rating
The MMI8000 Series front bezel is NEMA 4 rated. When installed properly in a NEMA 4 panel, the NEMA 4 rating
of the panel is not compromised. This means that fluids do not enter the panel during wash downs.
Electrical Environment
The MMI8000 Series has been tested to conform to European CE requirements. This means that the circuitry is
designed to resist the effects of electrical noise. This does not guarantee noise immunity in severe cases. Proper
wire routing and grounding insures proper operation.
Mechanical Environment
Avoid installing units in environments where severe mechanical vibration or shocks are present.

2.1.1 Location Considerations
Care should be taken when locating equipment behind the unit to ensure that AC power wiring, PLC output
modules, contactors, starters and relays, and any other source of electrical interference are located away from the
back of the unit.
Take particular note as 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.
