FM
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 on page 14 of this instruction manual.
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.
Refer to table 6 for additional information, figure 17 for the FM loop schematic, and figure 16 for a typical CSA/FM
approval nameplate.

ATEX
All Approvals
All ATEX approved units come with a combined nameplate which carries multiple approvals (intrinsic safety and dust,
flameproof and dust, and Type n and dust), as shown in figure 18. During installation, only one type of protection
method is allowed. The unit shall be marked by the end-user as to which protection method it was installed as and
shall not be changed or utilized in any other manner than was originally marked by the end‐user.
WARNING
For ATEX approvals only, end‐user must select and mark only one protection method upon installation. Once marked it
shall not be changed. Failure to follow these instructions will jeopardize the explosion safety of the transducer, and may
result in personal injury or property damage.
