Cut the positive and negative cables that will go from the power supply to the
load (battery, display board, distribution blocks, etc.) to the desired length.
Always use the proper sized cable based on the amperage of the power
supply and the distance between the power supply and the load (Please refer
to the chart at the end of this manual). Allow for proper routing of the cables.
Strip approx. 1” of insulation from one end of each cable. Insert the stripped
end of the positive (red) cable into the POS terminal on the end of the power
supply, and the stripped end of the negative (black) cable into the NEG termi-
nal. Firmly tighten the terminal screws. Strip approx. ½” of insulation from
the other end of the positive and negative cables, terminate the ends as
necessary, and attach the cables to the load. You may connect, although
not required for most installations, the ground terminal to chassis or any
other grounding source. The grounding terminal is located close to one of the
mounting tabs.
Note: The gounding terminal is primarily used for RV installations. If installing your power
supply into an RV, an additional cable (as short as possible) needs to go from this terminal
to the chassis ground of the RV. If ground loop noise is present, a wire connected
from the NEG terminal to the chassis ground connection may correct the condi-
tion.
Dual Voltage Switching
The output voltage of any APS power supply (Except APS-100) may be ad-
justed from 13.6 volts to 14.2 volts when necessary. APS Power Supplies
feature an RJ45 phone jack on the top of the unit located by the cooling fans
(see photo below left). The unit is shipped with a jumper taped to the unit.
With the jumper removed, the output is 13.6V. With the jumper inserted, the
output is 14.2V. (Jumper wiring is shown in the following diagram; right).

Warning!

It is recommended that switching the output voltage on any APS power sup-
ply to 14.2 volts be done ONLY when rapid recharging of the battery is re-
quired. Long term connection at the 14.2V output level will result in
permanent battery damage.
