Installing The Supervisory Link Cables - GE Hydran 201 i Instruction Manual

Chapter 7 • Hydran 201Ci-C Installation
The procedure is as follows:
1. Remove the rubber plugs from the required openings of the H201Ci-C enclosure.
2. For each cable being used, install a standard, watertight conduit fitting (not supplied).
Up to eight conduits may be installed (supervisory links, ac power supply).
3. Mount a conduit to each fitting.
4. Ground the conduits and/or cable shields at some point. Follow the company
regulations meticulously.
7.3.4

Installing the Supervisory Link Cables

Note: The supervisory link cables have already been run into conduits up to the
Hydran 201Ci-C if the installation of the Hydran 201Ti's is completed (see Section 6.3.9
on page 6-26).
1. If required, trim the excess length from the end of the supervisory link cables to be
wired into the H201Ci-C.
Note: The total maximum length of all supervisory link cables connected to one H201Ci-C
is 1,200 m (4,000 ft).
2. Ensure the four wires of each cable have been labelled (for identification purposes)
at both ends.
3. Connect the wires and shield of one cable to one of the four H201Ci-C's termination
boards. For wiring details, see Table D-8 on page D-5.
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-C's
termination board.
