Hazardous Area Classifications and Special Instructions for “Safe Use” and
Installation in Hazardous Locations
Certain nameplates may carry more than one approval, and each approval may have unique installation/wiring
requirements and/or conditions of “safe use”. These special instructions for “safe use” are in addition to, and may
override, the standard installation procedures. Special instructions are listed by approval.
Note
This information supplements the nameplate markings affixed to the product and the i2P-100 instruction manual
(D103198X012
Always refer to the nameplate itself to identify the appropriate certification.
i2P-100 Electro‐Pneumatic Transducer
), available from your Emerson sales office or Local Business Partner, or at www.Fisher.com.
WARNING
Failure to follow these conditions of “safe use” could result in personal injury or property damage from fire or explosion,
and area re‐classification.
Special Conditions of Use
Intrinsically Safe, Explosion-proof, Type n, Non‐incendive, Dust‐Ignition proof
1. When product is used with natural gas as the pneumatic medium, the maximum working pressure of the natural
gas supply is limited to 50 psi.
2. When product is used with natural gas as the pneumatic medium the product shall be provided with the proper
remote venting, as described in the i2P-100 instruction manual (D103198X012).
3. The apparatus enclosure contains aluminum and is considered to constitute a potential risk of ignition by impact or
friction. Care must be taken into account during installation and use to prevent impact or friction.
