Wire up the system according to the standard connection diagrams and
other relevant documents provided in the appendix.
If installation-specific connection diagrams have been provided for a
given system, these supersede any connection information contained in
standard connection diagrams.
Ship's cables are directly connected to screw-down terminals on the
master PCB.
Insert the ship's cables through the inlets at the sides of the compass
housing. Remove the outer cable covers, draw back the cable shields
and fasten the cables with clamps or tie-wraps to the threaded studs of
the inlet plates. Refer to dimension drawing 4914-0112-02 in the appen-
dix.
Route the wires connecting to TB1 – TB4 through the inlets on the left
hand side of the housing.
Route the wires connecting to TB5 – TB7 through the inlets on the right
hand side.

`^rqflk Risk of malfunction through wrong wiring
Wrong wiring, especially as running wires from one side of the compass
housing to the other or across the master PCB will cause malfunction.
Always use the cable inlets on both sides of the compass housing for
accurate wiring and keep all wires running inside the housing as short as
possible.
Always avoid to run wires from one side of the compass housing across
to the other.
`^rqflk Risk of earth faults
Wrong wiring of the cable shields makes the cables act as antennas
resulting in earth faults.
Always make sure to correctly draw back the cable shields and fasten the
cables to avoid earth faults.
kçíÉ
In case of earth faults, it is recommended to always check first the cable
wiring for correctly connected cable shields.
