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 WILLBE 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

3 INTRODUCTION TO THE AC36V, AC45V, AND AC54V
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-
70Hertz, 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 forAC 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.
FIGURE 1 SYSTEM BLOCK DIAGRAM

AC36V-1, -3 / AC45V-1, -3 / AC54V-1, -3 Operations Manual....9
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. 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 maintenance and service can be provided with only top and front access to the system.
Three 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 maintenance and service: 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 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.

5 INSTALLATION
The installation section is divided into two parts. The first will cover mechanical installation, the
second, electrical installation.
Read this manual thoroughly prior to attempting the installation. Improper installation is the most
significant cause of system start-up problems and service issues over the product’s life. Upon
receipt of the equipment, perform an external visual inspection. Verify that nameplate information
is consistent with the ship’s power requirements (required form, voltage, and frequency).
Proper planning will speed up installation, location, and connection of the equipment. Follow the
suggested minimumclearances providedin Table 2. Ensure the room/compartmenthasadequate
ventilation and cooling. The thermal load presented by AC36V will be approximately
10,500BTU/Hr at maximum continuous load, 13,060BTU/Hr for the AC45V, and
15,670BTU/Hr for the AC54V.

5.1 MECHANICAL INSTALLATION
The converters were designed for deck mount installations and as such are provided with six
mounting holes, three per side. Mounting holes have been provided with ½” (12.7mm) diameters;
stainless steel hardware in the range of 3/8” to 7/16” (10-11mm) diameter is required.
The mounting surface should be flat and dimensionally stable to within 1/16” (1.5mm) to prevent
torsional stresses being applied to the structure of the converter. Spacers (shimstock) may be added
between the mounting surface and the converter mounting flanges to adjust the mounting plane. If
the system is to be mounted in a high vibration/shock environment, then the factory must be
consulted concerning the application. Drawings for approved shock mounting assemblies will be
supplied.
The following recommended clearances must be considered during installation for proper operation:
TABLE 2

Upper Sides 6" (Exhaust Airflow) 0"
Top 0" ( Upper Side Exhaust) 8"
8" (Top Exhaust) 8"
Rear 5" (Intake Airflow) 0"
Air intake grillwork is provided on the bottom, rear, and lower side panels of the equipment. A total
intake area of 300 in2must be provided through a combination of surfaces, excluding that area
provided by the bottom. Please contact factory engineers for review of the installation plan if unsure
on any specification or requirement.

All power wiring requires the removal of the front panel, the interior safety cover, and the power
cable access cover (cabinet bottom). This cover is secured with 6 ea 1/4-20” x ½” stainless steel
screws. Drill or punch the appropriate holes for the selected strain reliefs. Re-install the input

5.2.1 Input Power Connections
The converter is supplied with compression type terminal blocks for input power connections.
These terminal blocks accept wires in the range of 250MCM to 6AWG. Refer to the applicable
standards for selection of required wire gauge and type. If single phase shore power is to be used, it
must be applied between the SHORE POWERPhase A and Phase B terminal blocks. In two cabinet
systems, one shore cord is connected to each converter shore power input.

Each system is supplied with compression type terminal blocks for output power connections. These
terminal blocks accept wires in the range of 250MCM to 6AWG. Refer to the applicable standard

Multi-cabinet systems connect outputs at the switchgear panel. It is recommended that connection
be made to the distribution bus through a manually operated disconnect device such as a molded
case switch or circuit breaker (rated for the total system amperage) for ease and safety of service in
the event of converter failure. The internal power contactors manage power control to the
distribution bus applying power through keypad, Auto-Restart,and remotecontrol based commands.

5.2.3 Seamless Transfer Connections
If the Seamless Transfer Option was ordered with the system, connections must be made between
the generator and the converter. These connections are used by the converter to successfully manage
the seamless transfer operation and are comprised of control, signal, and feedback functions. These
connections are only required on the Master cabinet of a multi-cabinet installation. The use of 14-
18AWG wire is recommended for signal and control wiring.
Figure 5 on page 21 depicts the power and signal connections for a typical installation. Generator 1
connections only are shown for clarity. Generator 2 connections are identical.
Contact the factory for complete and specific system wiring drawings. These can be supplied
in either printed or electronic format.
A motorized circuit breaker is used for generator transfer in the example, with line voltage operated
actuator coils. The control signals provided by the converter are momentary. The control pulse
width for the momentary control signals is 0.6 seconds for both the open and close commands. The
contacts used for generator control are rated for a maximumof 8A @250VAC or 5A @24VDC. The
generator contactor or circuit breaker must be equipped with an auxiliary switch contact set--closed
when the main contacts are closed.
The generator voltage sense wires are used by the converter to match its output voltage, frequency,
and phase angle to the generator’s and should be fused at the generator.
