Do not modify connectors of shore power supply cable, use only plug compatible connectors. If the yacht power supply cable cannot be plugged into the shore socket, ask the Port Authority for an adapter.

Check the specifications of the frequency converter for the entire input range.
Check the correct voltage before switching on each input power switch.
Maintenance must be carried out by qualified staff. Turn off the power and disconnect the ground wires before maintenance.

Powering the on-board converter through the ground sockets with voltages outside the operating range (170-520V) can cause irreversible damage to the equipment. You should ALWAYS check the value of the phase voltage of ALL and three phase-to-phase combinations before giving voltage to the electrical panel.

Before connecting the shore socket, ensure the type of voltage and the sockets available, their integrity and the absolute absence of moisture on the wire, on the socket and on the plug.
With plug connected check that wire:

• Cannot get in traction as a result of tide variations, yacht movements, etc..;
• Cannot get crushed, etc..

Do not allow that cable end of shore power supply to floats in the water. This can cause an electric field and following injuries or even the death of the swimmers nearby.

Before carrying out any intervention on the electric system, disconnect all circuits and the shore plug.

Risk of electric shock from leakage currents. Never swim in waters near harbours or marinas.

At least once every two weeks, have the various connections of electric boards, panels and boxes checked by experienced and equipped personnel. Make sure that ground connections of electric equipment and electrical panels are tight and not oxidized.
At least once a month check the status of the shore socket and eventually clean it.

• Put in OFF switches on Shore Line Switch electrical panel
  Put in OFF protections on the pedestal of the shore.
• Disconnect the power cord from the ground power source (from the shore pedestal).
• Securely close the lid of the power supply from shore.

Have the frequency converter, RCDs, electrical panels and other parts of the electrical system inspected by an electrician authorised by CUSTOM LINE to ensure correct operation and to detect any signs of overheating.

The AC system has characteristics similar to those of the home systems; for this reason, it is necessary to periodically check the conditions of the grounding system, of the residual current circuit-breakers and of the protection devices installed. The electric system is one of the most frequent causes of fire on board; therefore, it must be dealt with the utmost care and frequently checked.

Before carrying out any intervention on the electric system, disconnect all circuits (shore and generators):

• Disconnect the shore socket;
• Turn OFF the magneto-thermal switch of the generator.

FIRE DANGER
It is normal for converters to generate and emit a lot of heat.
Take caution not to surround drives with stowage material and keep them clear of obstructions to ensure they always receive adequate ventilation.
Do not store flammable material near the converters.

The converter installed on board, separates galvanically the shore electric system from the electric system of the yacht. During the periods of yacht’s lay-up for maintenance, if the shore electric socket is used to supply the AC on board electric system, make sure to connect the yacht grounding to the shore column grounding to which you are linked, taking advantage of experienced personnel.
