xvi Safety Instructions
CAUTION
Risk of damage/restricted freedom of roll and pitch
An overhanging gyrosphere supply and pick off cable may restrict the
freedom of roll and pitch of the gyrosphere container.
The gyrosphere container can only use its full freedom of roll and pitch
when the gyrosphere supply and pick off cable is pushed deeply into the
bellows and the cable length minimized.
Always make sure to deeply push the gyrosphere supply and pick off
cable into the bellows to minimize the cable length when installing the
gyrosphere container. Never allow overhanging of the gyrosphere sup-
ply and pick off cable when installing the gyrosphere container.
CAUTION
Risk of damage to the gyrosphere
The gyrosphere is always to be transported in its carrying box in the orig-
inal transport container.
Do not throw or drop the transport container.
The transport container is to be transported in an upright position only.
CAUTION
Risk of damage to the gyrosphere
Carry the carrying box containing the gyrosphere by hand only and han-
dle it with extreme care.
Remove the gyroshpere from the carrying box only if required for imme-
diate installation.
CAUTION
Risk of EMC exceeding
Sperry Marine requires to install the main power and a backup power
supply for the NAVIGAT 100 through the strip-wound core inside the
compass housing to meet EMC values.
Never install the power supplies of the NAVIGAT 100 without using the
strip-wound core.
CAUTION
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 NAVIGAT 100 mainboard 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.
CAUTION
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.
