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.

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
