Safety
ProSafe Isolation Transformers are provided with an access cover to facilitate installation and
should never be operated without this access cover securely mounted in place.
CAUTION: ONLY QUALIFIED PERSONNEL SHOULD INSTALL, INSPECT, OR MAINTAIN
TRANSFORMERS SINCE THE NORMAL OPERATING VOLTAGES CAN BE HAZARDOUS.
INSTALLATION OF THE TRANSFORMER
In addition to fore mentioned safety concerns, proper installation of the transformer is required
to insure quiet transformer and prevent the development of objectionable sound levels. The
following installation rules are to be followed for a quiet Installation:
•
Consider the installation and location of the transformer before engaging in
installation. Modifications to correct sound can be expensive.
•
Place sound dampening pads between the transformer and its mounting
surface.
•
Install transformer as far away as possible from any area where sound is
objectionable.
TRANSFORMER LIFE
Transformer life is dependent upon the thermal degradation of the insulation system which in
turn is dependent upon the winding temperature and duration of operation at that Temperature.
Factors which affect transformer life are line voltage, load current, load cycle, ambient
temperature, and other environmental conditions such as moisture, corrosive atmosphere,
vibration, and maintenance. Normal conditions of operation are covered in this manual and in
various industry standards.
CIRCUITS, TAPS AND CONNECTIONS
The ProMariner ProSafe Isolation transformer has up to four input and four output terminals.
Four input terminals accommodate a single input voltage when inter-connected. Four output
terminals provide a single output voltage or two voltages and a neutral when inter-connected.
Connections:
Input and output wires must be connected to their respective terminals with an
appropriately sized lug rated for the input or output current.
The following wiring diagrams are sample configurations that can
be used with the ProSafe Isolation Transformers:
