Quick Start
Tools Required
Flat Tip Screwdriver with 1/8.Blade, Wire Strippers.

Connections
All connections involve two inputs from the DCC booster,
or the main line track bus and two outputs to the insulated
track section or reverse block.
If your DCC output or mainline track bus is 16 ga or greater (smaller
wire) then connect directly to the screw terminals on OnGuard.
If your DCC output or mainline track bus is 10-14 ga wire then
solder-splice a short length of 16 AWG to your heavier bus wire
and connect the16 ga wires to screw terminals.
Polarity for Input/Output
OG-AR: Any input/output polarity is acceptable
for OG-AR
OG-CB: Input/output polarity must be the same for all OG-CB installations
Helpful Hints
When Isolated and Reverse Sections exceed
10 Ft. in length install at least 2 sets of track feeders
for that section. Lack of feeders causes a voltage loss.
For reverse sections, we recommended that
the gaps be staggered about 1/8". Perfectly aligned gaps
may reduce performance.
If your Power Sections and Reverse blocks
are greater than 10 Ft. long be sure to have at least 2 sets
of track feeders for that section. Insufficient feeders will
cause a voltage drop.
One end of the reverse section will be aligned
with normal polarity track power while the opposite or other
end will have a polarity mismatch and require the reverser
to act.
Note: Not for direct current (DC) applications.
