4.5 ELECTRICAL CONNECTIONS
WARNING
Let installation work be done by a
licensed electrician. Before beginning
with the connection of the wiring, make
the DC distribution voltage free.
CAUTION!
Short circuiting or reversing polarity may
lead to serious damage to the batteries,
the alternator, the Alpha Pro regulator,
the cabling and/or the terminal
connections. Fuses can not prevent
damage caused by reversed polarity. The
damage as a result of reverse polarity is
not covered by the warranty.
CAUTION!
Too-thin cables and/or loose connections
can cause dangerous overheating of the
cables and/or terminals. Therefore
tighten all connections well, in order to
limit transition resistance as far as
possible. Use cables of the correct size.
See specifications (section 8) for
recommended wire sizes
• Use the supplied cable harness for connection of
the Alpha Pro regulator
• DC Cables to connect the Battery to the
