4.1
Installation of the Compass Housing
The compass housing is to be attached to a level surface, e.g. a floor or console by
means of six M10 bolts or welding studs (to be supplied by the shipyard). At the place
of location of the compass, proper ventilation must be ensured and sufficient space
provided for the housing to be opened and maintenance work to be carried out. The
amount of space required, the attachment points and the position of the cable inlets
are shown in the dimension drawing at the back of this manual.
In the horizontal plane, the compass may be installed at any angle with respect to the
vessel's longitudinal axis. Alignment error (i.e. the angle between the compass' and
the vessel's longitudinal axis) is corrected electronically by setting the alignment er-
ror correction value in the service setup 1 (see 4.4.2).

Electrical Connections
4.2.1
The Connection Diagram
Each gyrocompass system is supplied with an installation-specific connection dia-
gram. The connection diagram provides the information needed to fit and connect all
cables required by the gyrocompass system.
All cables supplied by the manufacturer carry identification labels, as do all plug con-
nectors. These identifications may also be found in the connection diagram.
4.2.2
Connecting the Ship's Cables
Except for the AC power supply cables, all ship's cables are directly connected to
terminals on the masterboard.
Insert the ship's cables through the inlets at the sides of the compass housing. Re-
move the outer cable covers, draw back the cable shields and fasten the cables with
clamps or cable bands to the threaded studs as shown in the dimension drawing at
the back of this manual.
To connect the individual wires, remove the terminal strips
from their sockets. After wiring, fasten the strips to the sock-
ets with their securing screws.
All wires running inside the housing should be kept as short
as possible. Avoid to lead wires from one side of the housing
to the other. The data and signal inputs as well as the status
outputs and connections to the operating units and the switch-
board are located on the left hand side of the masterboard (TB2 – TB4). The serial
data outputs, the analogue rate of turn output and the repeater power supply connec-
tions are located on the right hand side of the masterboard (TB5 – TB7).
