Replacing the Terminal Block Assembly
1. Turn off transmitter power source.
2. Screw in cover lock (if present) and remove the Field Terminals compartment cover by
rotating it counterclockwise.
3. Remove the four socket head screws securing the terminal block.
4. Disconnect the loop wiring connector from the terminal block.
5. Remove the terminal block and the gasket under it.
6. Install new gasket.
7. Reconnect the loop wiring connector to the new terminal block.
8. Install the new terminal block and resinstall the four screws to 0.56 N m (5 lb in) in
several even increments.
9. Reinstall the cover onto the housing by rotating it clockwise until the O-ring contacts
the housing; then continue to hand tighten as much as possible (at least 1/4 turn). If
cover locks are present, align the serration in the cover with the lock and unscrew it
until it extends into the cover serration to prevent unwanted cover rotation.
10. Turn on transmitter power source.
Rotating Process Covers for Venting
As received, the IDP10 Transmitter provides sensor cavity draining without the need for side
drain connections, regardless of whether the transmitter is mounted vertically or horizontally.
Sensor cavity venting is provided by mounting horizontally or with the optional vent screw (-V).
However, if you did not specify this option, you can still achieve venting (instead of draining)
with vertical mounting by rotating the process covers. See Figure 28.
