Wiring Guidelines
Safety Guidelines
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.

Enclosures
The terminal must be mounted in a panel or enclosure to protect the
internal circuitry. The terminal meets NEMA Type 4, 12, 13 (indoor
use only) ratings only when mounted in a panel or enclosure with the
equivalent rating.
Allow enough spacing within an enclosure for adequate ventilation.
For some applications, you may have to consider heat produced by
other devices within a panel. The ambient temperature around the
terminal must be maintained between 32_ – 131_ F (0_ – 55_ C).
Make sure that provisions are made for accessing the back panel of
the terminal for wiring, routine maintenance, and troubleshooting.

sealing compounds.
Disconnect all electrical power from the panel before
making cutout.
Make sure that area around panel cutout is clear.
Take precautions so that metal filings or other debris does not
fall into the DTAM Micro ventilation slots or enter any
components that may already be installed in panel.
Make sure that no objects are inserted or fall into the terminal
through the ventilation slots or DIP switch access hole.
Failure to follow these warnings may result in personal injury
or damage to the panel components.
3. Place the DTAM Micro in the panel cutout.
ATTENTION:
!
4. Install the six self locking mounting nuts hand tight.
5. Alternately tighten the mounting nuts until the DTAM Micro is
held firmly against the panel. Tighten mounting nuts to a torque
of 8 to 10 inch-pounds. Do not over-tighten nuts.
Mounting nuts must be tightened to a torque of 8 to 10 inch
pounds to provide a proper seal and to prevent potential
damage to the terminal. Allen-Bradley assumes no
responsibility for water or chemical damage to the terminal or
other equipment within the enclosure because of improper
