Perform the following procedure to make wiring connections:
Procedure
1. Remove the housing cover on terminal compartment side. Do not remove the
cover in explosive atmospheres when the circuit is live. Signal wiring supplies all
power to the transmitter.
2. Ensure full contact with terminal block screw and washer. When using a direct
wiring method, wrap wire clockwise to ensure it is in place when tightening the
terminal block screw.
Note
Emerson does not recommend using a pin or ferrule wire terminal, as the
connection may be more susceptible to loosening over time or under vibration.
3. Plug and seal the unused conduit connection on the transmitter housing to avoid
moisture accumulation in the terminal side. Install wiring with a drip loop. Arrange
