NORAC UC4+BC+HD1 - Manual (Page 24)

Read all the following installation
instruction before connecting the
NORAC Power Cable (C10).
Ensure the UC4 Control Panel’s
power is OFF for the remaining
installation (Bottom of switch
pressed IN). Use caution when
handling the 12 V power line of
the sprayer wiring.
2. The Hardi control box does not require
the polarity of the power source to be
Negative Ground. However, before
connecting C10 you must ensure your
Hardi system is wired as Negative
Ground. Follow the procedure below
to check the polarity.
a) Locate the Yellow (left boom) and
White (right boom) wires in either
the Hitch connection or the Hardi
control box.
b) Using a meter or test light and
connect one probe to Ground and
the other probe to the Yellow or
White wire. If the wire has voltage
without the switch being activated,
the polarity is reversed. Repeat the
test for the other wire.
c) Change the polarity of the Hardi
Control box. (Switch the Power
and Ground connections.)
d) With the meter connected as in
STEP b) check if either the Yellow
or White wire has voltage. Neither
wire should have any voltage. Flip
the switch to raise the booms. The
meter should now show voltage on
the Yellow or White wires and the
Hardi control box is wire correctly
with negative ground.
3. You can now connect the free hanging
wire of C10 (Sense lines) to Hardi
wiring. You can connect to the Hardi
wiring inside the hitch connection or
drill a 3/4" hole in the bottom of the
Hardi control box and install the
supplied compression fitting. With
either installation the wiring will be the
same.
4. Strip off a few inches of shielding from
the free hanging wire on C10. Strip the
ends of the Black and Brown Wires.
5. Connect the Black wire to the Hardi
Yellow wire and the Brown wire to the
Hardi White wire.
6. Connect the 16-pin AMP plug on C10
to the UC4+ Control Panel (Figure
25).
7. Connect the 3-pin AMP plug on C10 to
an auxiliary 12V power connection in
the cab.
8. Connect the 4-pin AMP plug on the
sensor trunk extension (C06) to the
UC4+ Control Panel.
9. Route C10 and C06 to the hitch.
10. Connect the 6-pin Shroud on the valve
extension cable (C04) to the 6-pin
Tower on C10.
The valve extension cable (C04)
may be packaged with one GP
end not installed. This is normal;
it helps installations for other
sprayer types. Pin this connector
on (connector included) as per
drawing in Section 5.5. TAKE
EXTRA CARE! These pins
require a special tool to remove
them if you make an error.
