3 INTRODUCTION TO THE AC24, AC30, AC36
Each model is a high performance Yacht Power Converter utilizing dual-conversion technology.
These converters will accept any single phase input service with a frequency between 40-70 Hertz,
and a voltage between 170-520VAC. Input service may consist of a single 100 (125, 150) Amp
shore cord, or dual 50 (63, 75) Amp shore cords. When operated from two shore cords, the two
shore cords must be of a like voltage form; the converter may be operated from two shore cords
protected by GFI/RCD type circuit breakers. When operated from a single shore cord, the SHORE
POWER 1 INPUT must be used. The output power form has been programmed at the factory for the
power form, voltage, and frequency, required by the yacht’s electrical system.
Dual-conversion technology is the preferred technique forAC power conversion, and was chosenfor
these converters. With 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 AC24, AC30, AC36, cont.
Being a unit designed from the ground up specifically for the yachting industry, all efforts have been
made to produce a system capable of sustaining the marine environment. All system components are
packaged in one 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 converter. 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 disconnect switchandmembranebutton
panel. A safety disconnect switch (red and yellow in color) near the top of the enclosure is used for
securing input service during maintenance and service. Three membrane button groups in the
control console, SHORE POWER, CONVERTER POWER, and SHIP’S POWER, provide normal
operation of the converter. The SHORE and CONVERTER switch groups contain ON and OFF
buttons with associated LED indicators; these buttons are used to turn ON and OFF the converter
input (SHORE POWER) and output (CONVERTER POWER). The SHIP’S group contains a
CONVERTER and GENERATOR button with associated LED indicators; these buttons are used to
manage Seamless Transfer when the option is included.
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 will be 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 products life. Upon receipt
of the equipment, perform an external visual inspection. Verify that nameplate information is
consistent with the ships 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 1. Ensuretheroom/compartmenthas adequate
ventilation and cooling. The thermal load presented by AC24 will be substantial,
approximately 6,888BTU/Hr at maximum continuous load, 8,610BTU/Hr for the AC30, and
10,332BTU/Hr for the AC36.

5.1 MECHANICAL INSTALLATION
The systems 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" (12mm) 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 panels will be
supplied.
The following recommended clearances must be considered during installation for proper operation:

5.2 ELECTRICAL INSTALLATION
This procedure assumes the physical installation of the converter has been completed. It is the users
responsibility to provide input service over-current protection and disconnect means. Follow the
table below for shore power wiring.

Dual Shore Cord 50A 63A 75A
Output Current 100A 125A 150A
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
service panel using the removed hardware. Place the disconnect switch in the OFF position.
INPUT WIRING MUST BE PERFORMED BY A QUALIFIED ELECTRICIAN

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 2/0 to 8AWG. Refer to the applicable standards
for selection of required wire gauge and type.
If only a single shore cord is to be used, it must be connected to the SHORE POWER 1 INPUT
terminal block. The inputs to each system are fully isolated with no phase orientation requirements
to the input power service if dual shore cords are used.

AC24/30/36 Operations Manual....20
5.2.2 Output Power Connections
Each converter is supplied with compression type terminal blocks for output power connections.
These terminal blocks accept wires in the range of 2/0 to 8AWG. Refer to the applicable standard
for selection of the required wire gauge and type. Please refer to the FIGURE 3 on the previous
page for additional detail.
Prepare the power cable by removing the outer cable insulation approximately 6". Strip the
insulation back exposing ½" of bare conductor on all three conductors. Insert the prepared cable and
strain relief assembly into the forward hole in the input service panel. Insert the wire ends into the
output terminal block as described below and tighten.
THE CONVERTER ISOLATES THE OUTPUT POWER FROM THE INPUT

BE CONNECTED PER ABYC STANDARDS.
For 120/240V or 110/220V two-phase systems, connect the ship’s electrical systemto the converter
output terminals: L1, N (Neutral), and L2. Connect N (Neutral) to chassis ground at the converter
panel or at the distribution panel. L1 and L2 will measure 120V or 110V in reference to N.
