7. Connect the analog output wires to the Supervisory Control and Data
Acquisition (SCADA) system.
8. If the Hydran 201Ti’s alarms are used, proceed as follows:
• Run the alarms cable through the second conduit up to the H201Ti.
• Connect the cable to the H201Ti’s Alarm Contacts 9-Terminal Block, the
electrical connections drawing can be found in APPENDIX A: ELECTRICAL
CONNECTIONS.
• Connect the cable to the SCADA system.
9. Run the three-wire ac power supply cable into the second conduit up to the
Hydran 201Ti.
10. Connect the cable to the H201Ti’s terminals L1/L, L2/N and E/G. For wiring
details, see the electrical connections in APPENDIX A: ELECTRICAL
CONNECTIONS.
11. Connect the other end of the cable to the power source.
Note: The earth/ground terminal (E/G) must be connected to the power source
ground (green wire) or directly to the transformer tank.
Never perform high-voltage tests (mega-ohm measurements
using a Megger* instrument) on cables connected to an H201Ti
or a Hydran 201Ci Controller. Never apply high voltages to the
components of a Hydran 201i System, as they are equipped
with surge protection devices that could be damaged by
Megger* tests.
