2. SAFETY NOTICES
The DBT12 is capable of transferring large amounts of electrical energy very quickly.
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.

DBT12 Operations Manual....6
THIS EQUIPMENT CONTAINS HIGH ENERGY, LOW IMPEDANCE
CIRCUITS! LETHAL POTENTIALS ARE CONTAINED WITHIN THE
UNIT EVEN WHEN IT IS APPARENTLY NOT OPERATING.
CARE MUST BE EXERCISED WHEN SERVICING THIS EQUIPMENT
IN ORDER TO PREVENT SERIOUS OPERATOR INJURY OR
EQUIPMENT DAMAGE.
DO NOT WORK ON OR OPERATE THIS EQUIPMENT UNLESS YOU
ARE FULLY QUALIFIED TO DO SO. NEVER WORK ALONE.
THE EQUIPMENT IS NOT IGNITION RATED, IT MUST NOT BE
OPERATED IN AREAS WHERE COMBUSTIBLE GASES MAY
ACCUMULATE.
DO NOT REMOVE THE SHORE CORD FROM THE DOCK PEDESTAL
WITHOUT FIRST OPENING THE DOCK OR YACHT BREAKER.
FAILURE TO DO SO MAY RESULT IN DAMAGE TO THE DBT12 AND
PEDESTAL.
OBSERVE THE FOLLOWING WHEN SERVICE AND MAINTENANCE
ARE REQUIRED:
REMOVE ALL JEWELRY FROM ARMS AND NECK WHEN
SERVICING THIS EQUIPMENT. THIS PREVENTS THE
POSSIBILITY OF SHORTING THROUGH THE JEWELRY TO OR
ELECTROCUTION OF THE OPERATOR.
WEAR SAFETY GLASSES WHEN SERVICING THIS EQUIPMENT TO
PREVENT EYE INJURY DUE TO FLYING PARTICLES CAUSED BY
ACCIDENTAL SHORT CIRCUIT CONDITIONS.
DO NOT REMOVE ANY PANELS OR COVERS WITHOUT FIRST
OPENING ALL CIRCUIT BREAKERS AND THEN REMOVING THE
INPUT SERVICE.
SERVICE OTHER THAN CLEANING AIR FILTER ELEMENTS
SHOULD BE REFERRED TO PERSONNEL AUTHORIZED BY THE
FACTORY TO SERVICE THIS EQUIPMENT.

3. INTRODUCTION TO THE DBT12
The DBT12 is a high performance Isolation Transformer designed to isolate and normalize the
shore power for reliable shipboard use.
Isolation is obtained through the use of a conservatively rated transformer compliant to the
requirements of ABYC E-11.7.2.8, and as such includes a full fault current shield. The
transformer also provides basic range normalization and a first level of electrical noise filtering
as shown in Figure 1.
Figure 1: Unit Block Diagram
Being a unit designed from the ground up specifically for the yachting industry, all efforts have
been made to produce a unit capable of sustaining the marine environment. All unit
components are packaged in single drip-proof, dust-resistant aluminum enclosure. Complete
maintenance and service can be provided with front and side access to the unit. Unit operation
is managed through one circuit breaker and the LCD display.

5. 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 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 1. Ensure the room / compartment has
adequate ventilation and cooling. The thermal load presented by the DBT12 will be
approximately 1,400 BTU/Hr. at full rated (12kVA) load.
THE DBT12 IS HEAVY, WEIGHING 127 lbs. (57.7 kg). 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 UNIT.
5.1. MECHANICAL INSTALLATION
The unit is designed for horizontal, floor-mounted installation. The mounting feet on each side
of the unit contain mounting holes that are 0.41” (10.3 mm) in diameter. Stainless steel
hardware roughly equivalent to 3/8” (9 to 10 mm) is required for mounting.
The mounting surface should be flat and dimensionally stable to within 1/16” to prevent torsional
stresses being applied to the structure of the unit. Spacers (shim stock) may be added between
the mounting surface and the transformer mounting ears to adjust the mounting plane. Resilient
mounts must not be used directly between the unit and the mounting surface. If the unit is to be
mounted in a high vibration / shock environment, then the factory must be consulted concerning
