2 SAFETY NOTICES
The AC08 and AC12 are capable of transferring very large amounts of electrical
energy 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 ENCLOSINGAN EXCLAMATION
POINT)INDICATES A CONDITIONTHATCOULD SERIOUSLYDAMAGE
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 CONDITION. 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 AC08 AND AC12
The AC08 and AC12 are high performance Yacht Power Converters that use dual-conversion
technology. The systems will accept any single phase input service with a frequency between 40-70
Hertz, and a voltage between 170-520VAC. The output power form has been programmed at the
factory for the power form, voltage, and frequency required by your yacht. Variable fan speed
control has been provided (fan speed tied to output current level).
Dual-conversion technology is the preferred technique forAC power conversion, and was chosenfor
these converters. In this technology, the shore power service is isolated by transformers then
converted to DC power by a Power Factor Correction (PFC) power supply. The output inverters
then convert the DC power back to the AC form (both voltage and frequency) required by the yacht.
Being systems designed from the ground up specifically for the yachting industry, all efforts have
been made to produce a system capable of sustaining the marine environment. All system
components are packaged in one drip-proof, dust-resistant aluminum and 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 front access to the system.

3 INTRODUCTION TO THE AC08 AND AC12, cont.
System operation is managed through three basic operators. A safety disconnect at the bottomof the
enclosure is used for securing input service during maintenance and service. Two membrane switch
groups in the control console, SHORE POWER and CONVERTER POWER, provide 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, these converters provide the user with a
sophisticated power analysis and monitoring capacity. All parameters for input and output power,
along with operations and status information, are available on the front panel display console.
Various displays are selected through a long-life, sealed membrane switch panel. All front panel
information is available through the serial port for remote display, status and diagnostics.
