Installation
Allow at least 1 inch of clearance all around the case for cooling. The best mounting congu-
ration is to mount the unit on a vertical surface oriented as shown. Use #10 screws of the
appropriate type for the mounting surface to securely mount the unit.
The case has 500 volts of isolation from both the input and output, so it may be mounted on
any surface without fear of electrolysis or ground fault.
The unit is supplied with input leads 0.8 meters (32 inch) long of #12 AWG. This should be
adequate to connect to a breaker panel or other source of power. If you need to extend the
wires, use at least #12 AWG wire, solder and heat shrink the connection to protect the joint.
Connect the Red wire to Positive, and the Black wire to Negative. If a unit with a 12V output
is being run from a 24V battery system, use a 40 amp panel breaker to feed power to it, and
use a 25 amp panel breaker for a 32V battery system. Use a 40 amp breaker to feed power to
a unit with a 24V output. Each VTC300 Series Voltage Converter should have its own breaker
in the panel.
To reduce radio noise to the absolute minimum, it may be necessary to bond the case to the
vessel ground. For this purpose a grounding stud has been provided next to the input wires.
Use a #6 ring terminal to terminate the ground wire.
Refer to the manufacturers specications and add up the current ratings for each device to
be connected to the unit. Make sure that the total load does not exceed the continuous rating
of the unit (50 Amps -12 or 35 Amps -24). The devices may be wired directly to the output
terminals of the unit, or the unit can be wired to a distribution panel if it is more convenient. If
the unit is wired to a distribution panel, run wires from each terminal to the panel.
If the unit is being used to operate a single sideband radio,
the radio should be the ONLY device connected.
