Safety Precautions
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your MD-215 Series.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings,
the wiring could overheat, causing serious damage to your equipment.
Temperature Caution!
Be careful when handling the unit. When the unit is plugged in, the internal components generate heat, and
consequently the outer casing may feel hot to the touch.
We recommend taking the following precautions to minimize heat build-up within the display:
•
Position the display within ±40° of the vertical.
•
Install an external fan to increase airflow upwards through the display if (a) the display is not positioned
within ±40° of the vertical, (b) the ambient temperature exceeds 25°C, or (c) the display is used in a
location with minimal ventilation.
Important Safety Precaution
Even though the display is rated to operate within the IEC 60945 standard of -15 to 55°C for marine
applications, it is best to ensure that the ambient temperature does not exceed 25°C. Doing so will increase the
life of your display and minimize service costs.
Grounding the MD-215 Series
Be sure to ground the MD-215 Series before powering it on. Grounding and wire routing help limit the effects
of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the
grounding surface prior to connecting the power.
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.
Earth Ground: See the figure shown below for the location of the earth grounding connector. Connect the
grounding wire to an appropriate grounded metal surface.
