Power up transmitter

This section provides the steps needed to power up transmitters. These steps
are unique based on the specific protocol used. Reference the appropriate
section listed below for the specific steps.
• Connect wiring and power up for wired HART configuration
• Connect wiring and power up F
• Connect the power module for WirelessHART
5.1 Connect wiring and power up for wired HART
configuration
Use the following steps to wire the transmitter:
Procedure
1. Remove and discard orange conduit plugs.
2. Remove the housing cover labeled "Field Terminals."
3.
Do not connect the power across the test terminals. Power could
damage the test diode in the test connection. Twisted pairs yield best
results. Use 24 AWG to 14 AWG wire and do not exceed 5,000 feet
(1500 meters). For single compartment housing (Junction Box
housing), shielded signal wiring should be used in high EMI/RFI
environments.
Connect the positive lead to the "+" terminal, and the negative lead to
the "–" terminal.
4. 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.
The use of a pin or ferrule wire terminal is not recommended as the
connection may be more susceptible to loosening over time or under
vibration.
5. If the optional process temperature input is not installed, plug and seal
the unused conduit connection. If the optional process temperature
input is being utilized, see
(Pt 100 RTD sensor)
When the enclosed threaded plug is utilized in the conduit opening, it
must be installed with a minimum thread engagement in order to
comply with explosion-proof requirements. For straight threads, a
