Main Power Cables (Battery Cables); Electrical Installation - Vetus 25 kgf 110 mm Manuel D'utilisation Et Instructions D'installation

Main power cables (battery cables)

The minimum diameter must be sufficient for the bow thruster
in use and the voltage drop must not be more than 10% of the
voltage supplied; see the table.
A main switch and fuse must be fitted in the 'plus' cable. A
Vetus battery switch is suitable here. The fuse protects the bow
thruster against overvoltage and at the same time protects the
vessel's wiring against short-circuits.
Fuse
A suitable fuse is available for the bow thruster, see table. We
can also supply suitable fuse holders for all fuses, Vetus art.
code: ZEHC100.

Electrical installation

Make sure that no other electrical parts come loose
when connecting the electric cables.
Check all electrical connections after 14 days. Electrical
parts (such as bolts and nuts) may come loose as a
result of fluctuations in temperature.
Check that the voltage, recorded on the motor type plate, is in
agreement with the vessel's circuit voltage. Position the battery
or batteries as close as possible to the bow thruster; the main
power supply cables can then be short, which reduces the volt-
age drop as much as possible.
Connect the main power supply cables.

The maximum operating time and the thrust as speci-
fied in the technical details are based on the recom-
mended battery capacity and the battery connection
cables, see the 'Installation instructions'. If apprecia-
bly larger batteries in combination with very short con-
nection cables with appreciably larger diameter than
recommended are used then the thrust will increase.
In such cases the maximum operating time must be
reduced in order to prevent damage to the motor.
In extreme cases, for example when a battery with a
capacity of five times or more than suggested is used,
there is the danger of causing permanent damage to
one or more of the following shaft connections:
- The connection between motor shaft and the tail
piece input shaft.
- The connection between the tail piece output shaft
and the propeller.

Fit the control panel next to the steering position. There must be
at least 50 mm space behind the panel.
Fit the control
cable between the
bow thruster and
the control panel
through the vessel
and connect the
jack connections
together.
If it is necessary to
cut the intermediate
cable and recon-
nect it take care to
ensure the correct
colours are connected together.
N.B: The colours of the wire cores in the intermediate cable may
differ from the wire core colours as used on the bow thruster
motor and on the control panel!
