Electrical checks
This section of the manual contains the test procedures for the SBP 29 system’s power
and signal interface cables.
WARNING
These checks must be completed before any power is switched onto the system
Cabling
Visual inspection
Refer to the cable plans and interconnection diagrams, and check all power and
interconnection cables. Any locally fitted plugs and connectors should also be checked
to ensure that the correct types have been used for the specific locations. (Sealed or
spark-proof connectors in areas where flammable gasses may accumulate, etc.)
Ensure that all cable connections have been made according to the cable plan, and that
all connections are tight and secure. Ensure that all cables are correctly laid in conduits,
or are otherwise protected according to the regulations and recommendations laid down
by the vessel’s registering authority. Ensure all protective covers are fastened correctly.
Cable connections and continuity
After the cable connections have been completed and the visual inspection has been
carried out, all the cable cores must be checked for correct connection and continuity.
Refer to the cable plans and interconnection diagrams, and check all interconnection
cables. Any locally fitted plugs and connectors must be checked for shorts or open
circuits. Ensure all cable connections have been made according to the cable plan, and
that all connections are tight and secure.
The check procedure will require two engineers equipped with two-way communication
devices; one will require continuity test equipment, while the other will require a suitable
shorting strap.
Follow the check procedure below for each cable core
1 Position yourselves one at each end of the cable to be checked. Good
communications must be established between you and your assistant.
2 Ensure that the cable to be tested is not connected to any power source.
• If a cable terminates in a plug at the unit, the test will be more easily conducted if
the plug is disconnected.
3 Select one pair of cable cores, and check that the cores are connected to the correct
terminals in the unit.
4 Connect your continuity tester to the two terminals in question and check the
continuity.
