2.1.2 Making a NEMA-4 Mounting
Panel
The unit can be mounted into panels with a depth of 4"(105mm). It is recommended that
Details
the unit be mounted on the front panel of a steel enclosure, through an appropriate
opening*. Allow a clearance of 1"(25mm) around the sides of the unit for mounting
hardware. Allow clearance for cable connections to the back of the unit. Unit depth may
vary according to cable type used. Typically, plan a depth to accommodate at least
4"(105mm) behind the panel.
NEMA-4
Put the unit through the panel cut out. Slide the clamps into the 9~10 holes provided
Mounting
around the case. Tighten the clamping screws in an even pattern until the unit is secured in
the panel.
Caution!
Do not over tighten mounting clamps!
Specifications
Note:
Note: To seal to NEMA-4 specifications, all supplied mounting clamps must be used and
panel cannot flex more than 0.010".
2.1.3 Environmental Considerations
The MT-600/8000 are to be used indoors as built in displays. Make sure that the displays
are installed correctly and that the operating limits are followed (See Specifications).
Do not operate the unit in areas subject to explosion hazards due to flammable gases,
vapors or dusts.
The unit should not be installed where fast temperature variations and/or high humidity
are present. This will cause condensation of water in the device.
Do not install these terminals in environments where have inflammable gases.
2.2 Power Connections
Make sure that all local and national electrical standards are met when the installing the unit.
Contact your local authorities to determine which codes apply.

Condition
The MT-600/8000 can be powered by DC power only. The specified
voltage range is 24±10% Volts DC. This insures compatibility with
most controller DC systems.
The power conditioning circuitry inside the unit is accomplished by a
switching power supply. The peak starting current can be as high as 2A.
If the display does not come on within 2 seconds of power up, remove
power. An internal fuse will prevent damage if the polarity of the DC
power is incorrect. Check wiring to insure proper connections and try to
power up again.
An Internal fuse will prevent damage for over voltage condition
however it isn't guaranteed.
DC voltage sources should provide proper isolation from main AC
power and similar hazards.
A Hard-wired EMERGENCY STOP should be fitted in any system
using an MT-600/8000 to comply with ICS Safety Recommendations.
Do not power the MT-600/8000 and inductive DC loads, or input
circuitry to the controller, with the same power supply. Note: The 24
VDC output from some controllers may not have enough current to
power the MT-600/8000.
