Main Current Cables - Vetus EAIR05024 Installation Manual

- The batteries must be easily accessible for maintenance.
- Never fit switches or other electrical equipment in the vicinity of
batteries; possible sparks could cause an explosion.
- Prevent metal objects from accidentally coming into contact with
a battery terminal.

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!
When installing the electrical installation, always consult the
locally applicable regulations.
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.
A (system) voltage higher than 33 V causes irreparable da-
mage to the installation!
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.
