2 SAFETY NOTICES
Each shore power converter is capable of transferring large amounts of electrical energy very
quickly. This quality is fundamental to a high performance powerconverter. International symbols
are used throughout this manual to stress important information. Read the text below each symbol
carefullyand use professional skills and prudent care when performing the actions described bythe
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
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 CONVERTERS
Each model is a high performance Yacht Power Converter utilizing dual-conversion technology.
The systems will accept any three phase input service with a frequency between 40-70Hertz, and a
voltage between 170-520VAC.
The output power form has been programmed at the factory for the voltage and frequency required
by your yacht.
Dual-conversion technologyis the preferred techniqueforACpowerconversion,and waschosen for
each system. In this technology, the shore power service is isolated by the transformer, then
converted to DC power by the phase multiplier power supplies. The output inverters then convert
the DC power back to the required AC form (both voltage and frequency) required by the yacht.

3 INTRODUCTION TO THE CONVERTERS, cont.
Being a converter designed from the ground up specificallyfor the yachtingindustry,alleffortshave
been made to produce a system capable of withstanding the marine environment. The system is
constructed using a modular approach where the converter consists of a control module (upper),
three power modules (middle) (two for the AC50Q-3), and a transformer module (bottom). This
allows the converter to be broken down into five parts to facilitate its movement into a vessel
through existing personnel entry points. All system components are packaged in drip-proof, dust-
resistant, aluminum chassis. Major components are internally modular, allowingasimpleexchange
in the unlikely event of failure. Maintenance and service are performed through top access to the
upper control module, exchange of power modules, and front/top access to the transformer module.
Fan speed control is provided. Internal cooling fans will run at full rpm when the converter is at full
load, and minimal speed while unloaded.
System operation is managed through three basic operators:
A safetydisconnect on the front of the enclosure is used for securinginput service duringperiods of
disuse, when maintenance and/or service is in-process, or when an emergencyshutdown is needed.
Three membrane switch groups in the control console—SHOREPOWER,CONVERTERPOWER,
and SHIP’S POWER—provide normal operation of the system. Each switch group contains an ON
and OFF switch with associated LED indicators.
Each power module has an ON/OFF switch for disconnecting the power module from the converter
when non-operational—the converter may be operated with one or two power modules in-service.
In addition to the basic function of power conversion, each converter 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 available 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.
