CAUTION
SHOCK/FIRE HAZARD
Replace automatic breakers or fuses with same amperage. Never alter
overcurrent protection.
S
CAUTION
AC ELECTRICAL SYSTEM: EXTREME HAZARD
Extreme hazard - swimming near a vessel equipped with AC-electrical
system operating can lead to severe shock or death. Never swim or
allow anyone to swim when the AC-system is powered.
S
CAUTION
A.C. CIRCUITS CAN DELIVER A LETHAL SHOCK!
Before opening an electrical distribution panel or servicing any
electrical equipment:
− disconnect the shore power cord;
− stop the generator;
− deactivate the main battery disconnectors.
S
CAUTION
Do not replace your vessel’s circuit breakers of fuses with breakers or
fuses of higher amperage than those installed by BERTRAM. Choose
differential circuit breakers and fuses for the spare circuits with ratings
that match the load of the equipment, but do not exceed the current
carrying capacity of the cables in each branch circuit.

DANGER
Extreme danger:
− Never use open flames in the battery storage area.
− Prevent sparks from reaching the battery.
− The battery can explode if, while charging, a spark or a flame turn on,
due to the hydrogen released.
S
CAUTION
SHOCK/FIRE DANGER:
− Disconnect the electric system from the mains before starting any
maintenance work. Never perform any maintenance work on the
electric system while under voltage.
− The electric devices should never exceed the rated voltage of the
yacht electric circuits.
− Check carefully the electric system while under voltage.
The only electrical components which can be left unattended are the
automatic bilge pumps, fire protection and alarm circuits.
