The power terminals are polarity insensitive: the polarity of the DC power leads does not
matter when connecting to the power terminals.
When wiring to screw terminals, crimped lugs are recommended. Tighten the terminals to
ensure adequate contact. No additional power wiring is required.
Both transmitter covers must be fully engaged to meet explosion proof requirements. Do
not remove the transmitter covers in an explosive atmosphere when the transmitter is
powered.
