3 INTRODUCTION TO THE AC36/45/54VHES
The AC36VHES, AC45VHES, and AC54VHES are high performance Shore Power Converters
utilizing dual-conversion technology. These converters will accept any single or three phase
input service with a frequency between 40-70Hertz, and a voltage between 170-520VAC; 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.
FIGURE 1 SYSTEM BLOCK DIAGRAM
Dual-conversion technology is the preferred technique for AC power conversion, and was
chosen for the system design. In this technology, the shore power service is isolated by
transformers and then converted to DC power by the Power Factor Correction (PFC) power
supplies. The output inverters then convert the DC power back to the AC form required (both
voltage and frequency) by the yacht.
These models are a dust-sealed variation of the standard “V” converter series and are cooled via
an integrated liquid-to-air heat exchanger when plumbed to the yacht’s chilled water loop.

AC36VHES-1, -3 / AC45VHES-1, -3 / AC54VHES-1, -3 Operations Manual....9
The converter is designed to have the heat it introduces into its internal atmosphere cooled via
this back -mounted, air-to-liquid heat exchanger. The heat-exchanger is designed for use with
chilled water or coolant (not seawater).
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 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 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 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 minimum clearances provided in Table 2. The thermal load presented by the
converter to the chilled water loop will be substantial and approximately 10,500BTU/Hr at
maximum continuous load for the AC36VHES; 13,060BTU/Hr for the AC45VHES; and
15,670BTU/Hr for the AC54VHES.
THE CONVERTERS ARE HEAVY, WEIGHING UP TO 840lbs
DEPENDING UPON MODEL AND INSTALLED OPTIONS. EXTREME
CAUTION MUST BE EXERCISED IN HANDLING AND INSTALLATION
TO AVOID EQUIPMENT DAMAGE OR INJURY TO PERSONNEL. AN
ADEQUATE MATERIAL HANDLING DEVICE SHOULD BE USED FOR
UNLOADING, MOVING, AND POSITIONING THE SYSTEM.

AC36VHES-1, -3 / AC45VHES-1, -3 / AC54VHES-1, -3 Operations Manual....15
5.1 MECHANICAL INSTALLATION
5.1.1 General
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 1/2” (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 (shim stock) 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.
5.1.2 Clearances
The following recommended clearances must be considered during installation for proper
operation:
TABLE 2 FOR PROPER:

5.1 MECHANICAL INSTALLATION
5.1.3 Chilled Water Loop Requirements
1. Coolant lines
a. The four coolant line connections are to 1/2" diameter copper pipes.
b. Use Teflon sealant to ensure that no leakage will occur.
2. Coolant line valves
a. Manual isolation valves must be installed locally so that shutoff can occur in the event
maintenance or a leak.
b. A flow control solenoid must be installed to halt coolant flow when the converters are
not in use. Without such, condensation can be created within the converter.
c. A flow control solenoid may be controlled by wiring its coil through a NO auxiliary
switch added to the converter’s K2 contactor. This way, flow will only be present when
the converter is switched to SHORE POWER ON.
3. Rear-bottom condensation drip line
a. The rear-bottom condensation drip line connection is made to a 3/8" diameter painted
steel pipe.
b. Use Teflon sealant to ensure that no leakage will occur.
4. Maintenance
a. No maintenance need be performed on the heat exchange unit when it is used in a
chilled, fresh water or ethylene glycol system.
5. Flow
a. A coolant flow rate greater than 16 GPM (Gallons Per Minute) is wasteful and can
accelerate water erosion of the heat exchange unit’s copper piping and sweated junctions.

5.2 ELECTRICAL INSTALLATION
This procedure assumes the physical installation of the converter has been completed.
It is the installer’s responsibility to provide input service over-current protection and disconnect
means.
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) to ease disconnection and provide a safe servicing environment in the event of
converter failure.
Follow the table below when considering shore power input cabling.
