2 SAFETY NOTICES
The AC08 and AC12 are 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 ENCLOSINGAN EXCLAMATION
POINT)INDICATES A CONDITIONTHATCOULD SERIOUSLYDAMAGE
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.

3 INTRODUCTION TO THE AC08 AND AC12
The AC08 and AC12 are high performance Yacht Power Converters that use dual-conversion
technology. The systems will accept any single phase input service with a frequency between 40-70
Hertz, and a voltage between 170-520VAC. The output power form has been programmed at the
factory for the power form, voltage, and frequency required by your yacht. Variable fan speed
control has been provided (fan speed tied to output current level).
Dual-conversion technology is the preferred technique forAC power conversion, and was chosenfor
these converters. In this technology, the shore power service is isolated by transformers then
converted to DC power by a Power Factor Correction (PFC) power supply. The output inverters
then convert the DC power back to the AC form (both voltage and frequency) required by the yacht.
Being systems 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 drip-proof, dust-resistant aluminum and 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.

3 INTRODUCTION TO THE AC08 AND AC12, cont.
System operation is managed through three basic operators. A safety disconnect at the bottomof the
enclosure is used for securing input service during maintenance and service. Two membrane switch
groups in the control console, SHORE POWER and CONVERTER 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, these converters provide 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. All front panel
information is available through the serial port for remote display, status and diagnostics.

5 INSTALLATION
Read this manual thoroughly prior to attempting equipment installation. Improper installation is the
most significant cause of system start-up and service problems over the product’s life. Perform an
external visual inspection upon receipt of the equipment. Verify that the nameplate information is
consistent with the ship’s power requirements (required form, voltage, and frequency).
Proper planning will speed up location, installation, and connection of the equipment. Follow the
suggested minimumclearances providedin Table 1. Ensuretheroom/compartment has adequate
ventilation and cooling. The thermal load presented by the converters will be substantial:
approximately3,470 BTU/Hr for theAC08 and approximately 4,750 BTU/HrfortheAC12at
maximum continuous load.
THE AC08 AND AC12 ARE HEAVY, WEIGHING UP TO 230lbs (104kg).
EXTREME CAUTION MUST BE EXERCISED IN HANDLING AND
INSTALLATION TO AVOID EQUIPMENT DAMAGE OR INJURY TO
PERSONNEL. ANADEQUATEMATERIALHANDLINGDEVICESHOULD
BE USED FOR UNLOADING, MOVING, AND POSITIONING THE
SYSTEM.

AC08 and AC12 Operations Manual....13
5.1 MECHANICAL INSTALLATION
The converters are designed for vertical, bulkhead-mounted installations and as such are provided
with six mounting ears, three per side. The provided mounting holes are ½” (12.7mm) in diameter;
stainless steel hardware in the size range of 7/16” to ½” (11 to 12mm) is required for mounting.
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 ears to adjust the mounting plane.
Resilient mounts must not be used directly between the converter and the mounting surface. If the
converter is to be mounted in a high vibration/shock environment, then the factorymustbe consulted
concerning the application. Drawings for approved shock mounting panels will be supplied.
The converter may be mounted horizontally with the correct preparations to the mounting surface.
The factory must be contacted concerning the application prior to order/delivery of the system to
allow the required internal modifications to be included, and for concurrence on the application and
installation.
The following recommended clearances must be considered during installation:

5.2 ELECTRICAL INSTALLATION
This procedure assumes the physical installation of the converter has been completed. It is the
user’s responsibility to provide input service over-current protection and disconnect means.
Maximum continuous input current for the 8kVA AC08 is 40Amps, and for the 12kVA AC12 is
55Amps. A circuit breaker with a 60Amp rating is recommended.
All power wiring requires the removal of the lower front cover. This cover is secured with 15 ea 6-
32 x ¼” stainless steel screws. Do not remove the upper front cover, or the disconnect
switch/bracket assembly. Place the disconnect switch in the OFF position.
Remove the input service panel from the bottomof the system. This panel is secured with 10 ea 10-
32 x 3/8" stainless steel screws. The input service panel is supplied with two pilot holes for power
wiring strain reliefs. Drill or punch the appropriate holes for the selected strain reliefs. Drill a ¼”
diameter hole in the input service panel for equipment (safety) ground terminations. Re-install the
input service panel using the removed hardware.
INPUT WIRING MUST BE PERFORMED BY A QUALIFIED ELECTRICIAN

5.2.1 Input Power Connections
The converters are supplied with compression type terminal blocks for input power connections.
These terminal blocks accept wires in the range of 6-10AWG. Refer to the applicable standard for
selection of required wire gauge and type.
Prepare the power cable by removing the outer cable insulation approximately 6” (in the case ofSO
type portable cables). Strip the insulation back exposing ½” of bare conductor on all three wires.
Insert the prepared cable and strain relief assembly into the rearmost hole in the input service panel.
Follow the wire table in the illustration below for correct termination.
The input to the converters is fully isolated with no phase orientation requirements to the input
power service.

5.2.3 Grounding
The converter chassis ground MUST be connected to the ship’s hull or common ground point via the
compression fitting terminal adjacent to the outputpower connections. Failure to do so may create
conditions that may in turn cause injury or death to operators; failure to do so will also result in the
voiding of the equipment warranty. In the case of paralleled converter systems, and where such
ground connections are not local and directly adjacent to the paralleled converters, the chassis
ground connections must be interconnected between the paralleled converters as well as connected
to the remote ship’s common ground point.
