ATTENTION

ATTENTION

Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment
is considered Group 1, Class A industrial equipment according to IEC/CISPR

11. Without appropriate precautions, there may be difficulties with
electromagnetic compatibility in residential and other environments due to
conducted and radiated disturbances.
This equipment is supplied as open-type equipment. It must be mounted
within an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent personal
injury resulting from accessibility to live parts. The enclosure must have
suitable flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5V A, V2, V1, V0 (or equivalent) if
non-metallic. The interior of the enclosure must be accessible only by the use
of a tool. Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.
In addition to this publication, see:

• Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1
requirements.

• NEMA Standard 250 and IEC 60529, as applicable, for explanations of
the degrees of protection provided by different types of enclosure.

, for additional installation

Preventing Electrostatic Discharge

This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines when
you handle this equipment:

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging when not in
use.

WARNING

AVERTISSEMENT

North American Hazardous Location Approval

The following modules are North American Hazardous Location approved:
2080-TC2

The following information applies
when operating this equipment in
hazardous locations:

Products marked "CL I, DIV 2, GP A, B, C, D" are
suitable for use in Class I Division 2 Groups A,
B, C, D, Hazardous Locations and nonhazardous
locations only. Each product is supplied with
markings on the rating nameplate indicating the
hazardous location temperature code. When
combining products within a system, the most
adverse temperature code (lowest "T" number)
may be used to help determine the overall
temperature code of the system. Combinations
of equipment in your system are subject to
investigation by the local Authority Having
Jurisdiction at the time of installation.

EXPLOSION HAZARD

• Do not disconnect
equipment unless power
has been removed or the
area is known to be
nonhazardous.

• Do not disconnect
connections to this
equipment unless power
has been removed or the
area is known to be
nonhazardous. Secure any
external connections that
mate to this equipment by
using screws, sliding
latches, threaded
connectors, or other means
provided with this product.

• Substitution of any
component may impair
suitability for Class I,
Division 2.

• If this product contains
batteries, they must only be
changed in an area known
to be nonhazardous.

Informations sur l’utilisation de cet
équipement en environnements dangereux:

Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne
conviennent qu'à une utilisation en environnements de
Classe I Division 2 Groupes A, B, C, D dangereux et non
dangereux. Chaque produit est livré avec des marquages
sur sa plaque d'identification qui indiquent le code de
température pour les environnements dangereux.
Lorsque plusieurs produits sont combinés dans un
système, le code de température le plus défavorable
(code de température le plus faible) peut être utilisé
pour déterminer le code de température global du
système. Les combinaisons d'équipements dans le
système sont sujettes à inspection par les autorités
locales qualifiées au moment de l'installation.

RISQUE D’EXPLOSION

• Couper le courant ou s'assurer
que l'environnement est
classé non dangereux avant de
débrancher l'équipement.

• Couper le courant ou s'assurer
que l'environnement est
classé non dangereux avant de
débrancher les connecteurs.
Fixer tous les connecteurs
externes reliés à cet
équipement à l'aide de vis,
loquets coulissants,
connecteurs filetés ou autres
moyens fournis avec ce
produit.

• La substitution de tout
composant peut rendre cet
équipement inadapté à une
utilisation en environnement
de Classe I, Division 2.

• S'assurer que l'environnement
est classé non dangereux
avant de changer les piles.

ATTENTION

45010

Parts List

Your package contains one Micro800 Non-isolated Thermocouple plug-in
module, two module fastening screws, one trimmed/formed bendable lead
NTC thermistor and these pin out guide wiring instructions.

You can choose to wire the plug-in before inserting it onto the controller, or
wire it once the module is secured in place.

• This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR 11. Without appropriate precautions, there may be
difficulties with electromagnetic compatibility in residential and other
environments due to conducted and radiated disturbance.

• Be careful when stripping wires. Wire fragments that fall into the controller
could cause damage. Once wiring is complete, make sure the controller is
free of all metal fragments.

• Do not wire more than 2 conductors on any single terminal.

• If you insert or remove the plug-in module while power is on, an electrical
arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous
before proceeding.

• Use shielded twisted core cables to connect the sensor.

• The shield should be grounded only at controller end.

• Connect the thermocouples directly to the module.

• Do not insert or remove the plug-in module while power is applied,
otherwise, permanent damage to equipment may occur.

Wire the CJC Thermistor

2080-TC2 CJC Thermistor Wiring and Mounting Guide

The position for the thermistor, as illustrated, helps to compensate for
thermoelectric voltages developed at screw junction equally for
thermocouples connected to channels 0 and 1. If the bead is not in proper
contact with the screw, there will be deviation in readings due to inadequate
isothermal compensation.

This sensor is passive, non-polarized and readily available in the market.

Wire the Module in the Field

Connect the thermocouple sensors directly to the module terminals. If a
separate cable is used to connect the thermocouple to the module, the CJC
thermistor has to be mounted to the cable at thermocouple junction only.
