Installation
MOUNTING
Mount the unit in a DRY location. Allow at least 1 inch of clearance for adequate cooling.
POWER CONNECTION
The unit is supplied with input power leads 1 meter long. This should normally be adequate to
connect to a source of power. If you must extend the cable:
• Use the smallest extension length possible.
• Use no less than 10 gauge conductors.
• Splice and solder the joints.
• Protect the joints with heat shrink tubing.
Connect the wires to a 60 Amp source of power as follows:
• Red to Positive
• Black to Negative
OUTPUT CONNECTIONS
Two positive output terminals and two negative output terminals are provided. Connect only
one wire to each terminal. Ensure that the total average load connected does not exceed the
continuous current rating of the unit.
Note that the current specications are for input current. To obtain the maximum output
current capability at any given input voltage, use the following formula:
Output Current = Input Volts / Output Volts x 45
For example:
10 VDC in and 27 VDC out, the max output current = 10/27 x 45 = 16.7 Amps.
20 VDC in and 27 VDC out, the max output current = 20/27 x 45 = 33.3 Amps
Each output terminal can supply up to 25 Amps, therefore do not connect more than 25 amps
of load to either output terminal. If the load exceeds 25 Amps but not the continuous rated
output of the unit, do the following: The output terminals must be connected to the load in
parallel ensuring that the wiring used has sufcient capacity to handle the current.
