2 SAFETY NOTICES
Each shore power converter is 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 ENCLOSING AN EXCLAMATION
POINT) INDICATES A CONDITION THAT COULD SERIOUSLY DAMAGE
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 AC25QTP AND AC30QTP
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 40-70
Hertz, 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 for AC 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.

3 INTRODUCTION TO THE AC25QTP AND AC30QTP, cont.
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. The
system is constructed using a modular approach where the converter consists of a control module
(upper), three power modules (middle), and a transformer module (bottom). This allows the
converter to be broken down into five parts to facilitate its movement into a vessel through
existing personnel entry points. All system components are packaged in drip-proof, dust-
resistant, aluminum chassis. Major components are internally modular, allowing a simple
exchange in the unlikely event of failure. Maintenance and service are performed through top
access to the upper control module, exchange of power modules, and front/top access to the
transformer module.
Fan speed control is provided. Internal cooling fans will run at full rpm when the converter is at
full load, and minimal speed while unloaded.
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 system 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 5.
Ensure the room/compartment has adequate ventilation and cooling. The thermal load
presented by AC25QTP-1, -3 will be approximately 8,965 BTU/Hr at maximum continuous
load, and 10,760 BTU/Hr for the AC30QTP-1, -3 at maximum continuous load.
THE CONVERTERS WEIGH UP TO 472lbs (214kg) 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.

AC25/30QTP-1 and -3 Operations Manual.... 16
5.1 MECHANICAL INSTALLATION
The converter is designed for deck mount installations and as such is provided with eight
mounting holes, four per side. Mounting holes have been provided with 0.42" (10.75mm)
diameters; stainless steel hardware in the range of 1/4" to 5/16" (9-10mm) 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 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 5: Recommended Installation Clearances
Parameters Proper Operation Proper Service
Front 18" (Exhaust Airflow) 24" min.
Sides 0" 0"
Top (Excluding Keypad) 0" 14"
Rear 5" (Intake Airflow) 0"
Air intake grillwork is provided at the rear of the equipment. Please contact factory engineers
for review of the installation plan if unsure on any specification or requirement. Complete
installation drawings, both electrical and mechanical, will be supplied upon request. Please
contact the factory before attempting to disassemble the converter into its constituent parts.

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 a
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 for shore power wiring.

Refer to Table 3
All power wiring requires the removal of the front panel and the power cable access cover
(cabinet bottom). This cover is secured with 2 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.
