be installed adhering to the standards of the AYBC (American Boat and Yacht Council). Some guidelines are outlined below
but these notes do not replace the full guidelines detailed in the AYBC standard, always install the GP-IC-2000 using the AYBC
standard as the primary reference.
Safe AC and DC Ground Connection
As detailed in the last section when the AC power source is being supplied by shore power (Marina) the on board neutral must
be connected to the safety ground on the dock. This feature is automatically taken care of by the GP-IC-2000. When the AC
power source is being supplied by the Inverter (battery bank) the on board neutral must be connected to the common boat ground.
The DC ground terminal must also be connected to the common boat ground. This ensures that both the AC and DC ground
are connected to one common boat ground.
Corrosion
The GP-IC-2000 AC and DC terminals must be connected to the common boat ground to provide an important safety feature.
This ground connection can introduce the risk of galvanic corrosion and/or electrolysis of the boats underwater metallic hardware.
A galvanic isolator or an on board isolation transformer can be used to prevent galvanic corrosion.
