Battery-cables/lugs
Battery-cables must be related accordingly to the equipment
it is connected to. Please refer to the product specifications
for recommended relation between size and length.
Generally speaking, a thicker cable dimension will give
better performance, especially with longer cables. Use only
cable-lugs of high quality. These must only be mounted on
the cables with correct tool and correct according to the
procedure.
Never use a vise, wrench or similar to press on a cable-
lug. Although it may look like a good connection, over time
it may become a source of ignition.
The difference between two types of cable-lugs is clearly
shown in the picture. The left one illustrates a ring-type
cable-lug, and is acceptable for products with currents up to
ca 200A. The right cable-lug is of press-on type, and shall
be used on thrusters
Battery connection
The pictures show a correct connected battery cable.
Notice that the cable-lug is mounted onto the battery
post with washer and nut only on the upside of the
cable-lug. Nothing must be placed between the
battery terminal clamp and cable-lug.
It exists different kinds of battery connections. Use
only a type with bolts, and not any kind of ”spring”
or ”clip-on” solutions.
If more than one cable/cable-lug has to be mounted
on the same battery-post, the one with the greatest
current shall always be the lowest or closest to the
battery.
Follow the instructions for applying the correct torque
on the bolts.
After the cables have been mounted, protective and
isolating rubber-cap shall be mounted.
Fuse connection
The bolt itself is not an active current conductor, and
its only function is to assure a tight fit between the
fuse and the cable-lug.
The picture shows a correct connected cable to the
fuse holder. Please note that fuse and cable-lug is in
direct contact with a big washer over the fuse and
under the cable-lug. There must be nothing
between the fuse and the cable-lug.
Correct torque for a Stainless Steel bolt (A4),
is 20 Nm.
