Maximum Cable Lengths - Euphonix Max Air Manual

Euphonix Max Air Installation Guide
NOTE: If your installation requires a longer cable, contact Euphonix Sales for
selecting a variety of fiber-optic solutions.
NOTE: It is the responsibility of the system designers, system integrators, and
end users to assure that the choice of cabling, termination, equalizations, etc.
conform to the recommended practice. Although maximum recommended
distances over copper can be extended with the use of high performance com-
ponents (including cables), it is not Euphonix's intention to endorse any particu-
lar brand or method of achieving the end result.
Facility Power Quality Recommendations
Although a detailed exploration into the types of power quality issues is beyond the scope
of this manual, we'd like to briefly touch on a few of the most important mechanisms that
determine your facility's power quality. The following is a list of facility power
standards/specifications that is recommended for optimal and reliable performance of
your Euphonix console:
Harmonic Distortion
IEEE Standard 519, Recommended Practices and Requirements for Harmonic Control In
Electrical Power Systems, establishes harmonic limits on voltages for computers and
computer-based equipment. AC power sources shall have no more than a 5% harmonic
voltage distortion factor, with the largest single harmonic being no more than 3% of the
fundamental voltage. Higher levels of harmonics can result in erratic behavior and
unpredictable performance.
Ground resistance is the resistance due to the resistivity of the soil in the vicinity of the
grounding electrode. Most computer equipment manufacturers recommend a maximum
ground resistance of two ohms.
