Warnings
Explosions can result in death or serious injury.
• Do not remove the transmitter covers in explosive environments when the
circuit is live.
• Transmitter covers must be fully engaged to meet explosion proof
requirements.

that the instruments in the loop are installed according to intrinsically safe or
nonincendive field wiring practices.
Static electricity can damage sensitive components.
• Observe safe handling precautions for static-sensitive components.
