DTAM Micro Operator Interface

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 Micro terminal using publication NFPA 70E,
Electrical Safety Requirements for Employee Workplaces as a guide.
Be certain to follow all directions for installing and connecting DC
power to the DTAM Micro.
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.
Use only a Class 2 power source as described in the National
Electrical Code (ANSI/NFPA 70) and Canadian Electrical Code.
The recommended AC to DC adapters (Catalog No. 1747-NP1 and
Catalog No. 1747-NP2) meet this requirement.
The DTAM Micro contains no user serviceable parts.
