2 SAFETY NOTICES
Each shore power converter is capable of transferring very large amounts of electrical
en ergy very quickly. This quality is fundamental to a high performance power
converter. International symbols are used throughout this manual to stress important
information. Read the text below each symbol carefully and use professional skills
and prudent care when performing the actions described by the text.
THE CAUTION SYMBOL (TRIANGLE ENCLOSING AN EXCLAMATION
POINT) INDICATES A CONDITION THAT COULD SERIOUSLY DAMAGE
EQUIPMENT AND POSSIBLY INJURE PERSONNEL. CAUTIONS WILL
BE PRESENTED IN THIS FORM. ALL CAUTIONS SHOULD BE
RIGOROUSLY OBSERVED.
THE WARNING SYMBOL (TRIANGLE WITH A LIGHTNING BOLT) IS
USED TO SIGNAL THE PRESENCE OF A POSSIBLE SERIOUS, LIFE
THREATENING COND ITION. A CONDITION THAT IS HAZARDOUS
TO BOTH PERSONNEL AND EQUIPMENT WILL BE ISSUED AS A
WARNING. ALL WARNINGS WILL BE PRESENTED IN THIS FORM.

3 INTRODUCTION TO THE AC25V, AC30V, AND AC36V II
Each model is a high performance Yacht Power Converter utilizing dual-conversion technology. The
systems will accept any single or three phase input service with a frequency between 40-70Hertz,
and a voltage between 170-520VAC. Input service may consist of one single phase or one three
phase shore voltage; the converter will auto-configure for the applied power form.
The output power form has been programmed at the factory for the power form (single or three
phase), voltage and frequency, required by your yacht.
Dual-conversion technology is the preferred technique for AC power conversion, and was chosen
for each system. In this technology, the shore power service is isolated by transformers, then
converted to DC power by the Power Factor Correction (PFC) power supplies. The output inverters
then convert the DC power back to the required AC form (both voltage and frequency) required by
the yacht.

Being a unit designed from the ground up specifically for the yachting industry, all efforts have been
made to produce a system capable of withstanding the marine environment. All system components
are packaged in one drip-proof, dust-resistant stainless steel enclosure. Major components are
internally modular, allowing a simple exchange in the unlikely event of failure. Complete
maintenance and service can be provided with only top and front access to the system. Three
lightweight power modules can be removed and replaced through the front panel for repair or power
level upgrade.
System operation is managed through three basic operators. A safety disconnect on the front of the
enclosu re is used for securing input service during maintenance and service. Three membrane
switch groups in the control console, SHORE POWER, CONVERTER POWER, and SHIP’S
POWER, provid e normal operation of the system. Each switch group contains an ON and OFF
switch with associated LED indicators.
In addition to the basic function of power conversion, each system provides the user with a
sophisticated power analysis and monitoring capacity. All parameters for input and output power,
along with operations and status information, are availabl e on the front panel display console.
Various displays are selected through a long life, sealed membrane switch panel.
For additional information on controls and indicators, please refer to Section 6.
