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
