easiest-to-check conditions first.
Explosions can result in death or serious injury.
• Do not remove the instrument cover in explosive environments
when the circuit is alive.
• Both transmitter covers must be fully engaged to meet
explosion-proof requirements.
• Before connecting a 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.
Electrical shock can result in death or serious injury.
