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.

Equipment Required

Clearances

Other than the tools required to make the panel cutout, the tools
required for installation are:

• 7mm (M4) deep well socket wrench or nut driver

• small slotted screwdriver

• torque wrench (in. / lbs).

The terminal is tightened against the panel with six self-locking nuts.

Make sure that you leave adequate room, as shown in Figure 1, for
mounting, air flow, cabling, and access to DIP switches.

Recommended Clearances

Leave 3 inches (76.2 mm)

for Mounting, Air Flow, and

access to DIP Switches.

Leave 3 inches (76.2 mm) for

communications port connector.
