4 Connect wiring and power up
Procedure
1. Remove and discard orange conduit plugs.
2. Remove the housing cover labeled “Field Terminals.”
Note
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 24–14 AWG wire and do not exceed 5,000 ft. (1,500 m).
For single compartment housing (Junction Box housing), shielded
signal wiring should be used in high EMI/RFI environments.
3. Connect the positive lead to the “+” terminal, and the negative lead to
the “–” terminal.
4. CAUTION
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
minimum of seven threads must be engaged. For tapered threads, a
minimum of five threads must be engaged.
Plug and seal the unused conduit connection with the provided
conduit plug.
5. If applicable, install wiring with a drip loop. Arrange the drip loop
so the bottom is lower than the conduit connections and the
transmitter housing.
6. Reinstall the housing cover and tighten so the cover is fully seated with
metal to metal contact between the housing and cover in order to
meet explosion proof requirements.
