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 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.

ATTENTION: EXPLOSION HAZARD: SUBSTITUTION OF

COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS 1, DIVISION 2.

RISQUE D’EXPLOSION: LA SUBSTITUTION DE COMPOSANTS PEUT RENDRE CE MATÉRIEL INACCEPTABLE POUR LES EMPLACEMENTS DE CLASSE 1, DIVISION 2.

ATTENTION: USE P1 POWERED UNITS ONLY WITH CLASS 2 POWER SOURCE LIMITED TO 30 VDC OPEN CIRCUIT AND 8A SHORT CIRCUIT.

ATTENTION: UTILISER AVEC UNE TENSION D’ALIMENTATION CLASSE 2 DE 30 VCC MAXI EN CIRCUIT OUVERT AVEC UN COURANT DE COURT-CIRCUIT DE 8A MAXI.

ATTENTION: EXPLOSION HAZARD: DO NOT CONNECT OR

DISCONNECT EQUIPMENT WHILE CIRCUIT IS LIVE UNLESS AREA IS KNOWN TO BE NON-HAZARDOUS.

Enclosures

RISQUE D’EXPLOSION: NE PAS BRANCHER OU DEBRANCHER TANT QUE LE CIRCUIT EST SOUS TENSION, A MOINS QU’IL NE S’AGISSE D’UN EMPLACEMENT NON DANGEREUX.

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) or 4X (indoor 2707-V40P2N, -V40P2NR) 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 as specified. See Specifications Section for ratings.

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.

Installation

To install the DTAM Plus Operator Module:

ATTENTION:

1. Using the cutout template shown in Figure 3, cut an opening in the panel. Remove any sharp edges or burrs.

2. Make sure the sealing gasket is properly positioned on the DTAM Plus. This gasket forms a compression type seal. Do not use 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 do not

fall into the DTAM Plus 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 Plus in the panel cutout.

ATTENTION:

4. Install the six self locking mounting nuts hand tight.

5. Alternately tighten the mounting nuts until the DTAM Plus 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 panel enclosure because of improper installation.
