Environment and Enclosure

ATTENTION: 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 5VA or be approved for the application if nonmetallic. 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.

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

Prevent Electrostatic Discharge

ATTENTION: 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.

North American Hazardous Location Approval

The following modules are North American Hazardous Location approved: 2080-LC20-20QWB, 2080-LC20-20QBB, 2080-LC20-20AWB, 2080-LC20-20QWBR, 2080-LC20-20QBBR, 2080-LC20-20AWBR

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.

WARNING: 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.

AVERTISSEMENT: 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.

WARNING:

• If you connect or disconnect the serial cable with power applied to this

module or the serial device on the other end of the cable, 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.

• If you connect or disconnect the communications cable with power applied

to this module or any device on the network, 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.

• When used in a Class I, Division 2, hazardous location, this equipment must

be mounted in a suitable enclosure with proper wiring method that complies with the governing electrical codes.

• Exposure to some chemicals may degrade the sealing properties of

materials used in the Relays. It is recommended that the User periodically inspect these devices for any degradation of properties and replace the module if degradation is found.

• If you insert or remove the plug-in module while backplane 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. Refer to the Wiring Diagram for each plug-in module for additional details regarding removal or insertion under power.

• When you connect or disconnect the Removable Terminal Block (RTB) with

field side power applied, 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.

ATTENTION:

• The serial cables are not to exceed 3.0 m (9.84 ft).

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

• Do not remove the Removable Terminal Block (RTB) until power is removed.

ATTENTION:

• To comply with the CE Low Voltage Directive (LVD), this equipment must be

powered from a source compliant with the following: Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).

• To comply with UL restrictions, this equipment must be powered from a

Class 2 or Limited Voltage Limited Current Source (LVLC).

• For Class I Division 2 applications, use only Class I Division 2 listed or

recognized accessories and modules approved for use within the Micro800 platform.

ATTENTION:

• Electrostatic discharge can damage semiconductor devices inside the

module. Do not touch the connector pins or other sensitive area pins.

• 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 connect directly to line voltage. Line voltage must be supplied by a

suitable, approved isolating transformer or power supply having short circuit capacity not exceeding 100 VA maximum equivalent.
