Explosions could result in death or serious injury:
Do not remove the transmitter cover in explosive atmospheres when the circuit is
alive.
Before connecting a HART-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
Both transmitter covers must be fully engaged to meet explosion-proof requirements.
