10 Electrical installation

10.1 Choice of battery

The total battery capacity must be compatible with the size of the
'RimDrive' and the intended use, see table.
We recommend Vetus maintenance-free batteries, which are avail-
able in the following capacities: 55 Ah, 70 Ah, 90 Ah, 108 Ah, 120 Ah,
143 Ah, 165 Ah, 200 Ah and 225 Ah.
We would also recommend the use of a separate set of batteries for
the/each 'RimDrive' . Placing the batteries as close to the 'RimDrive' as
possible will result in shorter main power supply cables. In this way,
any power loss associated with long cables can be avoided.
See page 150 for the suggested battery capacity.

10.2 Charging facility

The common on-board charging systems are
either 12 Volt or 24 Volt.
A 'converter' is required when charging the
48 V battery set with the available on-board
voltage.

10.3 Main switch

see diagram page 148 - 1 -
The main switch must be fitted to the 'posi-
tive cable' .
The Vetus battery switch type BATSW250 is a
suitable switch.

10.4 Fuses

Main power fuse 1, see diagram page 148 - 2 -
In addition to the main switch and main re-
lay, a 200 A fuse must be fitted to the 'posi-
tive' cable. Vetus art. code: ZE200.
The fuse will protect the bow thruster from
overloading and provide short circuit protec-
tion for the on-board power net.

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 suit-
ed to this application.
Batteries that are not 'sealed' may produce small amounts of explo-
sive gas during the charging cycle.
Always use batteries of the same type, capacity and state of service.

We can also supply a fuse holder for all the
fuses, Vetus art. code: ZEHC100.
