• Flexible rather than rigid conduits should be used near the H201Ci-1 to ease
installation and servicing.
• Conduits, or cable armors, should be made of steel to shield against magnetic
fields.
The procedure is as follows:
1. Remove the rubber plugs from the required openings of the H201Ci-1 enclosure.
2. For each cable being used, install a standard, watertight conduit fitting (not
supplied). Up to six conduits may be installed (supervisory links, AC power supply
and analog outputs).
3. Mount a conduit to each fitting.
4. Ground the conduits and/or cable shields at some point. Follow the company
regulations meticulously.
9.3.4 Installing the Supervisory Link Cable
Note: The supervisory link cable has already been run into conduits up to the Hydran
201Ci-1 if the installation of the Hydran 201Ti is completed (see Section 7.3.9).
1. If required, trim the excess length from the end of the supervisory link cable from
the H201Ti.
Note: The total maximum length of the supervisory link cable connected to one H201Ci-1
is 1,200 m (4,000 ft).
2. Ensure the six have been labeled (for identification purposes) at both ends.
3. Connect the cable wires and shield to the H201Ci-1’s termination board. For
wiring details, see Table D - 11.
Note: The shield is grounded through a capacitor at the H201Ti end to protect against
radiofrequency interference. Shields must also be directly grounded at the H201Ci-1’s
termination board.
The H201Ci-1’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 H201Ci-1’s enclosure
9.3.5 Installing the Analog Output Cable (Optional)
Perform this procedure only if the Hydran 201Ci-1’s isolated, analog 4–20 mA output is
used.
1. Run an instrumentation-grade cable (twisted pairs with individual and overall
shields) through a conduit up to the H201Ci-1, or use an armored cable.
