Figure 1 – Installing the power converter
1.
Disconnect the battery/power source.
2.
Find a suitable location to install the power converter where it is protected from
the elements. Ensure
it’s a ventilated area to prevent the unit from
overheating.
3.
Measure the total length of wires that will be required to go from the power
source to the power converter to the Predatair. Measure both the power and
ground wire lengths, add them together, and select the correct wire size from
Table 1.
Total length of Power wire PLUS Ground wire
Recommended Wire Gauge
Less than 5 ft.

5 ft. to 8 ft.
10AWG
More than 8 ft.
8AWG
Table 1 - Wire guage size
4.
Run wires of recommended gauge from the power source to the power converter.
5.
Ensure the 24V power source is fused or place an inline 20A ATC/ATO fuse as
close as possible to the battery/power source.
Note: Any length of wire unprotected by a fuse is a potential fire
hazard.
6.
Attach wires coming from the power source to the Input and Ground terminals using
the unit’s set screws. Use Loctite 425 and fasten firmly, but do not over-tighten set
screws.
7.
Using wire size based on Table 1, e
xtend the Predatair interface cable’s RED and
GREEN wires to the power converter.
