Wiring Requirements

This section describes how to connect peripheral devices to the panel computer.

You should read and follow these common safety precautions before proceeding with the installation of any

electronic device:

• Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must

cross, make sure the wires are perpendicular at the intersection point.

NOTE Do not run signal or communication wiring together with power wiring in the same wire conduit. To avoid

interference, wires with different signal characteristics should be routed separately.

• Use the type of signal transmitted through a wire to determine which wires should be kept separate. The

rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.

• Keep input wiring and output wiring separate.

• It is advisable to label the wiring to all devices in the system.

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your MPC-2190 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 Requirements

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 MPC-2190 Series

Before you power on the MPC-2190 Series, please ground the MPC-2190 as 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.
