Electrical installation

6 .1

Choice of battery

The total battery capacity must be sufficient
for the size of the bow thruster; see the table.
See page 220 for the applicable battery ca-
pacity
We recommend Vetus maintenance free ma-
rine batteries; these can be supplied in the
following sizes: 55 Ah, 70 Ah, 90 Ah, 108 Ah,
120 Ah, 143 Ah, 165 Ah, 200 Ah and 225 Ah.
We also recommend that each bow thruster
is powered by its own separate battery or
batteries. This allows the battery bank to
be placed as close as possible to the bow
thruster; the main power cables can then be
short thus preventing voltage losses caused
by long cables.
Always use batteries whose type and capac-
ity are compatible for their use.
6 .2

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, consult the table on page 221.
6 .3

Main Switch

A main switch must be included on the 'posi-
tive cable' .
A Vetus battery switch is a very suitable
choice. Consult the following table for the
correct type of battery switch.

Be sure to only use 'sealed' batteries if
the batteries are located in the same
compartment as the bow thruster .
The Vetus 'SMF' and 'AGM' maintenance-
free batteries are ideally suited to this ap-
plication.
In extreme cases, for example when a bat-
tery with a capacity of five times or more
than suggested is used, there is the dan-
ger of causing permanent damage to one
or more of the following shaft connec-
tions:
The maximum operating time and the
thrust, as specified by the technical de-
tails in your bow thruster installation
and operating manual, are based on the
recommended storage battery capaci-
ties and storage battery connection ca-
bles .

The BATSW250 is also available with two poles, (Vetus art. code BATSW250T).

Batteries that are not 'sealed' may produce
small amounts of explosive gas during the
charging cycle.
Sparks generated by the carbon brushes
of the bow thruster motor may ignite this
explosive gas.

aution
- The connection between motor shaft
and the tail piece input shaft.
- The connection between the tail piece
output shaft and the propeller.

If considerably larger batteries in combi-
nation with very short connection cables
with considerably 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 .
