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 power converter. Internationalsymbols
are used throughout this manual to stress important information. Read the text below each symbol
carefully and use professional skills and prudent carewhen 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 THISFORM.
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
The AC36NVHE-3, AC45NVHE-3, and AC50NVHE-3 are high performance Shore Power
Converters utilizing dual-conversion technology. These 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 technology is the preferredtechniqueforAC powerconversion,andwaschosen for
these converters. In this technology, the shore power service is isolated by an input transformerand
then converted to DC power by an input rectifier. The output inverters then convert the DC power
back to the required AC power form (both voltage and frequency) required by the yacht.

3 INTRODUCTION TO THE CONVERTERS, cont.
Being converters designed from the ground up specifically for the yachting industry, alleffortshave
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 electrical maintenance and service can be provided with only front access to the system.
Two lightweight power modules can be removed and replaced through the front panel for repair or
power level upgrade.
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—SHOREPOWER,CONVERTERPOWER,
and SHIP’S POWER—provide normal operation of the system. Each switch group contains anON
and OFF switch with associated LED indicators.
In addition to the basic function of power conversion, the 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.
