Installation
Figure 2-10. Transmitter wiring
Note
Installation of the transient protection terminal block does not provide transient protection
unless the 3051S MultiVariable transmitter housing is properly grounded. See “Grounding” on
page 2-25 for more information.
Install optional process temperature input (Pt 100 RTD sensor)
Note
To meet ATEX/IECEx Flameproof certification, only ATEX/IECEx Flameproof Cables (Temperature
Input Code C30, C32, C33, C34 or customer supplied equivalent) may be used.
1. Mount the Pt 100 RTD Sensor in the appropriate location.
Note
Use shielded four-wire cable for the process temperature connection.
2. Connect the RTD cable to the 3051S MultiVariable transmitter by inserting the cable
wires through the unused housing conduit connection and connect to the four screws
on the transmitter terminal block. An appropriate cable gland should be used to seal
the conduit opening around the cable. See Figure 2-11 on page 23.
3. Connect the RTD cable shield wire to the ground lug in the housing.
