Mounting the IsoTransformer
The IsoTransformer may be mounted horizontally on a deck or vertically on a bulkhead.
Use appropriate equipment to hoist and rig unit. Care should be taken to ensure safety of individuals.
CAUTION
Horizontal Mount
Use care when drilling to avoid contact with any wires or live components.
WARNING – ELECTRICAL SHOCK HAZARD
Step
Action
1.
Carefully lower and position the IsoTransformer on the deck in the exact location the unit will be
installed
Note:
The wiring enclosure should be visible and accessible.
2.
Remove the IsoTransformer and drill four marked holes with the proper-sized drill bit
3.
Realign the IsoTransformer’s mounting holes with the drilled holes and fasten the unit to the deck with
the appropriate mounting hardware
4.
Firmly secure all mounting hardware.
Vertical Mount
Use care when drilling to avoid contact with any wires or live components.
WARNING – ELECTRICAL SHOCK HAZARD
Step
Action
1.
Carefully lower and position the IsoTransformer on the bulkhead in the exact location the unit will be
installed.
Note:
The wiring compartment should be at the bottom to ensure proper cooling of the unit.
2.
Remove the IsoTransformer and drill four marked holes with the proper-sized drill bit.
3.
Realign the IsoTransformer’s mounting holes with the drilled holes and fasten the unit to the bulkhead
with the appropriate mounting hardware.
4.
Firmly secure all mounting hardware.
Choosing the Appropriate Wire Type and Gauge
All input and output conductors should be at least 10 AWG, stranded, 600 volt rating, UL type AWM, UL 1426 or
equivalent, or a UL listed marine shore power cable. See ABYC standard E-8 for more details on conductor types
and sizing (gauge).
Note:
Use UL Recognized ring or captive spade terminals for making all connections to the terminal block re-
gardless of the wiring method chosen.
Choosing Electrical Wiring Hardware
The usual application for the IsoTransformer is as an isolation transformer. In this application, there is no fault
current path for the wiring from the shore power inlet to the IsoTransformer input connections. For this reason,
the wiring should only be done with a jacketed cable (.030 inches jacket thickness minimum) such as UL type
1426 boat cable or by using a UL listed marine cable set wire (type SO or equivalent). This wiring should be
installed in the boat in a protected area and routed to avoid contact with sharp edges or hot surfaces.
