DNGP Product Safety
For DNGP positioners intended for use with natural gas: Ensure that an adequate pressure relief provision is
installed when the application of system supply pressure could cause peripheral equipment to malfunction.
Installation must be in accordance with all local and national codes.
General installation, maintenance, or replacement
• Products must be installed in compliance with all local and national codes and standards by qualified
personnel using safe site work practices. Personal Protective Equipment (PPE) must be used per safe
site work practices.
Explosion Hazard: Do not disconnect equipment unless power has been switched off or the area is known
to be non-hazardous.
Do not remove the instrument cover or connect an electrical circuit unless the power is disconnected
(except as specifically noted herein).
Note: Ensure the area is properly ventilated.
Do not disconnect a pneumatic connection unless the power is disconnected. Natural gas will escape
into the surrounding atmosphere on disconnection of the pneumatic connections or removal of pressure
containing component.
