Endress+Hauser 17
4.9.1 Connecting the analog outputs/analog inputs
1. Disconnect power from the analyzer and open the electronics enclosure cover. Take care not to disturb the
electrical assembly inside.
2. Run conduit or rated armor cable with the appropriate cable glands (minimum Exe rated) from the analog
outputs/inputs receiving station to the conduit hub in the right outside corner of the electronics enclosure.
3. If using conduit, pull the customer-supplied cables for the source outputs through the conduit into the electronics
enclosure.
Figure 10. TB1/TB2 connections
If using rated armor cable, wires are already provided. Skip to step 4.
4. Strip back the jacket and insulation of the current loop output and serial cables just enough to connect to the
mating terminal block.
5. Connect the 4-20 mA current loop IOUT1/IOUT2 output wires to terminals 6 and 8, as shown in Figure 9 and
Table 7.
6. Connect the serial cable wires to the appropriate terminals according to Table 7 (TB1).
7. To complete the connection, connect the other end of the current loop wires to a current loop receiver and the
external serial cable to a serial port on your computer.
