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
