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.

THIS EQUIPMENT CONTAINS HIGH ENERGY, LOW IMPEDANCE
CIRCUITS! LETHAL POTENTIALS ARE CONTAINED WITHIN THE
SYSTEM—EVEN WHEN IT IS APPEARS TO BE NON-OPERATIONAL.
CARE MUST BE EXERCISED WHEN SERVICING THIS EQUIPMENT
IN ORDER TO PREVENT SERIOUS OPERATOR INJURY OR
EQUIPMENT DAMAGE.
DO NOT WORK ON OR OPERATE THIS EQUIPMENT UNLESS YOU
ARE FULLY QUALIFIED TO DO SO. NEVER WORK ALONE.
THE EQUIPMENT IS NOT IGNITION RATED, IT MUST NOT BE
OPERATED IN AREAS WHERE COMBUSTIBLE GASES MAY
ACCUMULATE.
DO NOT REMOVE THE SHORE CORD FROM THE DOCK PEDESTAL
WITHOUT FIRST OPENING THE DOCK OR YACHT BREAKER.
FAILURE TO DO SO MAY RESULT IN DAMAGE TO THE
CONVERTER AND PEDESTAL.
OBSERVE THE FOLLOWING WHEN SERVICE AND MAINTENANCE
ARE REQUIRED:
REMOVE ALL JEWELRY FROM ARMS AND NECK WHEN
SERVICING THIS EQUIPMENT. THIS PREVENTS THE
POSSIBILITY OF SHORTING THROUGH THE JEWELRY, OR
ELECTROCUTION OF THE OPERATOR.
WEAR SAFETY GLASSES WHEN SERVICING THIS EQUIPMENT
TO 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 AC25QTP AND AC30QTP
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.
