2 SAFETY NOTICES
Each shore power converter is 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 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.

AC25/30Q-1 and -3 Operations Manual....7
THIS EQUIPMENT CONTAINS HIGH ENERGY, LOW IMPEDANCE
CIRCUITS! LETHAL POTENTIALS ARE CONTAINED WITHIN THE

PREVENT EYE INJURY DUE TO FLYING PARTICLES CAUSED BY
ACCIDENTAL SHORT CIRCUIT CONDITIONS.
DO NOT REMOVE ANY PANELS OR COVERS WITHOUT FIRST
OPENING ALL SHORE POWER AND SWITCHGEAR CIRCUIT
BREAKERS DISTRIBUTING POWER TO AND FROM THE CONVERTER,
AND THEN REMOVING THE INPUT SERVICE.
SERVICE SHOULD BE REFERRED TO PERSONNEL AUTHORIZED BY
THE FACTORY TO SERVICE THIS EQUIPMENT.

3 INTRODUCTION TO THE AC25Q AND AC30Q
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 40-70
Hertz, 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 these systems. 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.

3 INTRODUCTION TO THE AC25Q AND AC30Q, cont.
Being a converter 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. The
system is constructed using a modular approach where the converter consists of a control module
(upper), three power modules (middle), 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, allowing a simple
exchange 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 two basic operators:
A safety disconnect on the front of the enclosure is used for securing input service during periods
of disuse, when maintenance and/or service is in-process, or when an emergency shutdown is
needed.
Three membrane switch groups in the control console—SHORE POWER, CONVERTER
POWER, and SHIP’S 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, 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 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.
