If there is the necessity of having to replace a fuse, proceed to its replacement with a new one having the same characteristics in order to avoid damage to the load board.

For the placement of fuses, refer to the wiring diagrams.

If your are compelled to use the “battery parallel connection”, turn off all electronic devices, so as not to jeopardize their correct operation.

The system is similar to a domestic system in terms of features and risks and, if “wrongly” used, mishandled and neglected, it statistically represents one of the most frequent reasons for fire on board.

Beware of electric shock hazard! Turn the power off before removing the cover and servicing any electrical equipment internal component.

Disconnect the shore power supply connections when the system is not in use.

All systems (included those operating at low voltage), if wrongly handled or overloaded, can originate short-circuits and heavy overheating, with consequent danger of fire spreading.

Do not modify the electric systems or relevant drawings. The installation, the modifications or the maintenance must be carried out only by a skilled naval electrician. Inspect the system at least once a year.

Before undertaking any navigation, check that the batteries are in good condition and that they supply the correct nominal current.

It is normal that the frequency converter generates and gives out a lot of heat.
Pay attention not to cover the frequency converter with stowing material and keep it free from obstructions, to ensure a proper ventilation. Do not stow flammable material close to the frequency converter.

To lower the of electrocution or fire hazard:

• Turn off switch for connection to shore supply of the yacht, before connecting or disconnecting the dock power supply cable;
• Disconnect the shore power supply cable (shore columns);
• Firmly fasten the lid of shore power supply socket.

NEVER:

• Work on the electric system while under voltage;
• Change an electrical system on the yacht or pertinent drawings: the installation, changes and maintenance must be performed only by a qualified electrician;
• Alter or modify the intensity of rated current of protections against overcurrent;
• Install or replace electric equipment or devices with components exceeding the rated current intensity of the circuit;
• Leave the yacht unguarded with electric system under tension, except for the circuits of the bilge automatic suction pumps, of fire-fighting protection and of alarm.

Remember to periodically check the battery status.
It also does not obstruct the vents.

Never reactivate magneto-thermal switches and circuit breakers forcibly, prior to location of the causes for the current cut-out.

Do not modify connectors of shore power supply cable, use only plug compatible connectors.

Refrain from performing any modification or intervention on the system and on the panel and take advantage of experienced Companies and skilled staff. Avoid particularly derivations on electric lines and splices of uses not provided for on the same panel. Finally, if uses have to be connected to the available switches, check that their amperage is suitable for the device installed.

Monitor the voltage of the engine and user batteries. During the charging phase 29.1V can be reached, this is a temporary value, well tolerated, both by the batteries and by the battery charger. This value has to be monitored and if this situation lasts for too long, the magneto-thermal switches of the battery chargers must be disconnected.

Always remember to disconnect the batteries before leaving the ship.

CUSTOM LINE suggests to examine very carefully the whole documentation delivered by the manufacturers of the various components; and for any problem relevant to maintenance, to contact directly CUSTOM LINE After Sales & Service Department.

Always keep batteries charged, also before leaving the ship for a long period, because the batteries discharge up to low level and following they can get irreparably damaged.

For a correct use of the power generators and for all prescriptions regarding their maintenance, carefully read the enclosed user instruction manual.

Before carrying out the switching over of the AC sources (generator/shore), it is advisable to disconnect all AC uses currently operating, to prevent damaging the electronic boards of the relevant devices.

Electrocution hazard! Turn the power off before removing the cover and servicing any electrical equipment internal component.

During the periods of yacht’s lay-up for maintenance (out of water), if the shore electric socket is used to supply the AC on-board electric system, always make sure that the yacht’s grounding system is connected to the grounding system of the shore column to which you are connected; do this with the aid of experienced personnel.

Before stopping the power generators, disconnect the various on-board uses supplied by them by following the correct procedures for switching off; stopping the power generators under load can irreparably damage the electronic control units of the various uses, beyond having a negative influence on the generators’ operation.
In any case, refer to the manual of each power generator to obtain detailed information about the procedures for switching it on and off.

The on-board lights (except for the engine room) are supplied with 24V.
Avoid touching them. In case it is necessary to replace, make sure that the relevant supply switches located on the electrical panel are set to OFF.

Any remote start and stop control of the engine control devices shall be capable of being disabled when the engine starting panel in the engine room is maintained.

EXPLOSION HAZARD
Any lithium battery powered device on board must be recharged only in open air areas, connected to a suitable charging system. Also please refer to the device dedicated Use and Maintenance Manual.
