Here are some recommendations on how to reduce electromagnetic
noise on the communications connections:
•
Careful wire routing helps reduce or minimize electrical noise.
Route incoming power to the terminal by a separate path from the
communications cables.
•
Do not run communications wiring and power wiring in the same
conduit.
•
Where communications and power wiring must cross, make their
intersection perpendicular.
•
Proper grounding helps to reduce the effects of noise due to
Electromagnetic Interference (EMI). To avoid problems caused
by EMI, all cables must be shielded and grounded at one end.
Grounding is also an important safety measure in electrical
installations. A source for grounding recommendations is the
National Electrical Code published by the National Fire
protection Association of Boston Massachusetts.
Install the DTAM Plus using publication NFPA 70E, Electrical
Safety Requirements for Employee Workplaces as a guide.
Be certain to follow all directions for installing and connecting
power to the DTAM Plus.
When used in a hazardous environment, the ultimate enclosure must
be in accordance with Class 1, Division 2 wiring methods as
described in the National Electrical Code (ANSI/NFPA 70) and the
Canadian Electrical Code.
All peripheral equipment must be suitable for the location in which it
is used.
For P1 powered units, use only a Class 2 power source as described
in the National Electrical Code (ANSI/NFPA 70) and the Canadian
Electrical Code.
