KPM(T) Series Flat Panel Industrial Monitor
Power Input Terminal Block
Use 18 AWG (1mm) wire or greater for the monitor power cable
Isolate the AC main circuit line, I/O signal lines, and power cord. Do not
bind or group them together.
To keep the temperature in range, the cooling air at the base of the system must not
exceed the maximum temperature specification (see Environmental Specifications in
Appendix A). Allocate proper spacing between internal components installed in the
enclosure. When the air temperature is higher than the specified maximum in the
enclosure, use a fan or air conditioner to lower the temperature.
Electrical noise is seldom responsible for damaging components, unless extremely
high energy or high voltage levels are present. However, noise can cause temporary
malfunctions that can result in hazardous machine operation in certain applications.
Noise may be present only at certain times, may appear at widely spread intervals, or
in some cases, may exist continuously.
Noise commonly enters through input, output, and power supply lines, and may also
be coupled through the capacitance between these lines and the noise signal carrier
lines. This usually results from the presence of high voltage or long, close-spaced
conductors. When control lines are closely spaced with lines carrying large currents,
the coupling of magnetic fields can also occur. Use shielded cables to help minimize
noise. Potential noise generators include switching components, relays, solenoids,
motors, and motor starters.
Refer to the relevant Federal, State/Provincial, and local electric codes, which
provide data such as the size and types of conductors, color codes and connections
necessary for safe grounding of electrical components. It is recommended that high-
and low-voltage cabling be separated and dressed apart. In particular, AC cables and
switch wiring should not be in the same conduit with all communication cables.
