WARNING
Electrical Systems
Service Life
The service life of your batteries is directly linked to the maintenance and treatment received. Every time a battery
is discharged below 60% of its capacity its service life is reduced.
Recharging
Under normal conditions the battery charger will take care of battery recharging. Should your batteries become
discharged because you are unable to use shore support and engines have not been used, a little consideration
will have to be given to recharging.
An interesting point here is that a battery will only recharge at approximately 10% of its total capacity i.e. if you
have used 20A of power for 4 hours a 100AH battery will be 80% discharged. To replace the charge the battery
charger will take 8 hours. That is if you are careful not to use too much power during this time as the shore support
will be using a percentage of its output recharging batteries.
Boost charging will recover discharged batteries quicker, but you are strongly advised not to use this method in the
confines of the engine compartment or even on your boat
.
Battery Terminals
Acid corrosion is far more serious than generally realised. It can cause sluggish starter operation and create
charging problems. The battery terminals should be clean and coated with suitable acid free and acid proof grease.
Always connect the positive cable first, negative last. Conversely, remove the negative cable first.
Maintenance
Do not smoke, produce sparks or work with a naked flame near a battery, this may cause an explosion. Always
wash hands thoroughly after handling batteries. Do not place tools or equipment on the battery as this could cause
a short circuit and explosion.
Batteries Taken Out Of Service
Should you take your battery out of service, such as winterising, it must be stored in a cool dry place and be
recharged every 1 to 2 months.
Bow thruster and generator starting batteries (when fitted) must also be included in the maintenance schedule.
MAIN POWER PANEL
General
This is mounted inside the cabin. It is split into two sections 220v AC main power to the left and 12v DC battery
power to the right. (Refer to wiring diagram Sht. 6)
AC Section
The 220V-230V AC section of the main power panel has a main switch which is a Residual Current Device
(R.C.D.). This switch has two functions; firstly it is the main switch, which turns the AC systems on;
ON (Up) OFF (Down)
Secondly it will trip itself off if there is a fault within the AC system.
The R.C.D. is also fitted with a test button, which should be pressed weekly with the system on to check that the
system is working correctly.
In the AC section there are also circuit breakers/switches for various items such as battery charger, water heater,
sockets, etc., should one of these become overloaded it will trip to the OFF position.
ON (Down) OFF (Up).
