6.5 Main current cables
• Connect the motor to the batteries as shown in the diagrams, see
page 72.
• Fit the fuse supplied and a main switch in the positive (+) cable.
When calculating the cable cross-sections, take into account a
maximum permissible voltage drop of 5%.
Never use smaller cable cross-sections than indicated in the
table below.

When the batteries are not being used or not charged, it is recom-
mended that they are disconnected from each other using an isolat-
ing switch.
NEVER fit the fuse, main switch or isolating switches in the
battery space!
Take the following points into account when installing the battery
cables:
- Fit the cables in the shortest possible way from batteries to motor.
- With a long cable length, bundle the '+' and '-' cables together.
- Install the '+' and '-' preferably in such a way that the total length of
each cable is the same. This ensures an equal load on each battery.
- Ensure that the cables do not run through any bilge water.
- Ensure that the cables cannot come into contact with any sharp
edges.

- Fix the cables in such a way to prevent wear or abrasion caused
by vibration.
- Use cable terminals to connect the cables to switches, fuse and
motor.
- Preferably fit cable terminals by crimping.
- Use good quality battery terminals to connect the cables to the
battery posts.
- Tighten bolts securely to ensure a good connection.
- Do not use spring-loaded battery terminals!
- Grease the battery posts and battery terminals with Vaseline to
prevent corrosion.
- Never change over the connector cables.
- Before leaving, check the charge status of the batteries just as you
would check the tank capacity of a diesel engine.
Changing over the plus (+) and minus (-) connections will
cause irreparable damage to the installation.
NEVER short-circuit the batteries by connecting the plus (+)
pole to the minus (-) pole.
Connecting the main current cables
• Switch all electrical equipment off.
• Prevent any short circuits caused by tools, for example.
• Connect the positive (+) cable first, then the negative.
