5.2 Connecting wires
All connections are made on the front of the case. No soldering is needed.
1. Connect signal connector terminals.
2. Connect compression type (X1 and X2) terminals for CTs/VTs.
3. Connect the terminals on the communication module for IRIG-B.
4. Connect the RTD inputs and mA outputs using shielded stranded cables and
connect the cable shield to GND rail.
5. Connect all the sensors of the same type to adjacent channels.
The cable shield is to be earthed at only one end of the cable with RTD
cable shield rail.
Use fine wire in door mounting.
