Installing the Cables
1.
Remove the cover from the connection box located under the brass adaptor.
2.
As required, install one or two watertight conduit fittings (not supplied) onto
the connection box.
•
One conduit is used to run the supervisory link cable (which connects the
H201T
i
to the Hydran 201C
i
Controller) and, if used, the cable of the
H201T
i
’s analog output.
•
One conduit is used to run the power supply cable and, if used, the cable
of the H201T
i
’s alarm contacts.
All cable connected to the H201Ti must be run through steel
conduits. Otherwise, armored cables can be used.
3.
Mount a conduit to each fitting.
All metallic conduits or cable shields must be connected to the
ground at one point.
4.
Ground the conduits and/or cable shields at some point. Follow the company
regulations meticulously.
The H201Ti must always be grounded, even if the transformer
tank is grounded at a single point and monitored for tank-to-
ground currents
.
5.
Run the supervisory link cable into the conduit up to the H201C
i
Controller,
the electrical connections drawings can be found in APPENDIX A: ELECTRICAL
CONNECTIONS.
6.
Connect the cable wires and shield to the H201Ti’s supervisory link (and
analog output) termination board. The electrical connections drawing can be
found in APPENDIX A: ELECTRICAL CONNECTIONS.
The H201Ti’s operation may be affected if wires are not
connected correctly. Be careful when installing and inserting
each wire. Be sure to insert all strands in the terminal; strands
that touch two terminals cause problems. Strip each wire to a
maximum of 8 mm before installing it. Do not leave trims of
metallic strands inside the H201Ti’s enclosure.
