The units withstand temperatures from 0º to 50ºC, and are fan-cooled. To keep the
temperature in range, the cooling air of the system must not exceed 50°C. Allocate
proper spacing between internal components installed in the enclosure. Units with
standard BIOS release 1.3 or greater will automatically throttle down the CPU
speed if the temperature exceeds the maximum allowed CPU 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, which can result in hazardous machine operation in
certain applications. Noise may be present only at certain times, may appear at
widespread 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 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 the
high voltage and low voltage cabling be separated and dressed apart. In particular,
the AC cables and switch wiring should not be in the same conduit with all
communication cables.
The unit’s power supply is built to operate with input voltage ranges of 100-132
VAC and 200-240 VAC, while still allowing the system to function within its
operating margin. As long as the incoming voltage is adequate, the power supply
provides all the logic voltages necessary to support the processor, memory, and
I/O.
