Hazardous Area Installation Warnings
Caution: When installed in a Class I. Div/Zone 2 hazardous location environment, this equipment must be installed in a min. IP54 certified enclosure.
Caution: Airflow around the switch must be unrestricted. To prevent the switch from overheating, there must be the following minimum clearances:
- Top and bottom: 1.75 in. (4.4 cm)
- Sides: 1.75 in. (4.4 cm)
- Front: 1.75 in. (4.4 cm)
Contact your Cisco Technical Assistance Centre (TAC) if tighter spacings are required.
Caution: When installed in a Class I. Div/Zone 2 hazardous location environment. this equipment must be installed in a pollution degree 2 environment per IEC 60664-1)
Caution: This equipment is suitable for use in Class I. Division 2. Groups A, B. C. D. or only nonhazardous locations.
Caution: Do not install or remove SFP or SFP+ modules when an explosive atmosphere may be present.
Caution: Do not install or remove power supplies when an explosive atmosphere may be present.
Caution: Do not use the USB Console Service Port when an explosive atmosphere may be present.
Warning: Exposure to some chemicals could degrade the sealing properties of materials used in the sealed relay device. Statement 381
Warning: This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017
Warning: To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of : 140°F (60°C) Statement 1047
Warning: When you connect or disconnect the power and/or alarm connector with power applied, an electrical arc can occur. This could cause an explosion in hazardous area installations. Be sure that all power is removed from the switch and any other circuits. Be sure that power cannot be accidentally turned on or verify that the area is nonhazardous before proceeding. Statement 1058
Warning: In switch installations in a hazardous location, the DC power source could be located away from the vicinity of the switch. Before performing any of the following procedures, locate the DC circuit to ensure that the power is removed and cannot be turned on accidentally, or verify that the area is nonhazardous before proceeding. Statement 1059
Warning: 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 interior of the enclosure must be accessible only by the use of a tool.
The enclosure must meet IP 54 or NEMA type 4 minimum enclosure rating standards. Statement 1063
Warning: Use twisted-pair supply wires suitable for 86°F (30°C) above surrounding ambient temperature outside the enclosure. Statement 1067
Warning: When used in a Class I, Division 2, hazardous location, this equipment must be mounted in a suitable enclosure with a proper wiring method that complies with the governing electrical codes. Statement 1069
Warning: Explosion Hazard—The area must be known to be nonhazardous before installing, servicing, or replacing the unit. Statement 1082
Note: This equipment has been tested by UL for the explosion, fire, shock and casualty hazards required by the applicable hazardous locations standards. UL certification does not cover the performance or reliability of any GPS hardware, GPS operating software, or other GPS-related aspects of equipment covered under this category. Accordingly, UL makes no representations, warranties or certifications regarding the performance or reliability of any GPS-related functions of equipment covered under this category.
North American Hazardous Location Approval
The following information applies when operating this equipment in hazardous locations:
Products marked "Class 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.
Informations sur l'utilisation de cet équipement en environnements dangereux:
Les produits marqués "Class 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.
