4 Hazardous Location Information Power, input and output (I/O) wiring must be in accordance with Class I, Division 2 wiring methods [Article (b) of the National Electric Code, NFPA 70] and in accordance with the authority having jurisdiction. Peripheal equipment must be suitable for the location it is used in. The equipment must be suitable for use in Class I, Div. 2, Groups A, B, C, and D Hazardous Locations and nonhazardous locations only.! Warning Explosion Hazard Substitution of components may impair suitability for Class I, Div. 2 Hazardous Locations. Different or lesser quality components may cause an explosion or other hazardous situation, which could result in death or serious injury, and/or damage to equipment. To avoid potentially hazardous situations, always use the appropriate components.! Warning Explosion Hazard Never disconnect equipment before powering off or before ascertaining that the area is nonhazardous. Disconnecting equipment before powering off or in a hazardous area may cause an explosion, which could result in death or serious injury, and/or damage to equipment. To avoid potentially hazardous situations, always power off equipment and assure that the area is nonhazardous before disconnecting. 4
