2.1.2 Making a NEMA-4 Mounting
Panel
Details
The unit can be mounted into panels with a depth of 4”(105mm). It is recommended that
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
Mounting
Put the unit through the panel cut out. Slide the clamps (packed with product) into the 8
holes provided around the case. Tighten the clamping screws in an even pattern until the
unit is secured in the panel. Screw Torque: 2.6~3.5 lbf.in. (For reaching waterproof effect
and to prevent the panel from being deformed.)
VESA
Mounting
There are 4 holes on back panel for locking VESA, The screw: M4 P0.7mm, length:
shorter then 8.0mm, and screw torque: 2.6 lbf.in.
Caution!
Do not over tighten mounting clamps!
Note:

Specifications
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
z
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).
z
Do not operate the unit in areas subject to explosion hazards due to flammable gases,
vapors or dusts.
z
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.
z
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.

2.2.1 Power Requirements
Power
The MT-600/8000 can be powered by DC power only. The specified voltage
range is
24±20%
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 700mA.
Fusing
Requirements
If the display does not come on within 5 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.

Caution

High Voltage
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.
