a. Open Pneumatic Hose access door. Remove and save two jam nuts, item (9), and two lockwashers, item (10)
from the top of the retaining bar, item (11), which is located on top of the inverter.
b. Remove retraining bar, item (11).
c. Remove and save two jam nuts, item (9), and two lock washers, item (10) from underneath the mounting tray,
item (15). Remove the two mounting studs, item (12) from mounting tray, item (15).
d. Remove black terminal cover, item (1) from negative (-) terminal. Do not remove black terminal cover from the
e. Remove red terminal cover, item (2) from positive (+) terminal. Do not remove red terminal cover from the wire.
f. Remove two nuts, item (3) and two lock washers, item (4) from the negative (-) and positive (+) terminal. move
the wires from the terminals.
g. Remove the inverter, item (14) from the mounting tray, item (15).
h. Push the red and black terminal covers onto the wires so that approximately 6 in. of white wire is exposed.
It Is Important to maintain the correct polarity of the positive and negative wires.
Reversing the polarity can cause damage to the new Inverter and possibly other
components. Follow the next steps carefully.
i. The positive white (+) wire with the red terminal cover shall be marked P54A10 if it is not already marked.
j. The negative white wire (-) with the black terminal cover shall be marked P54A10N if it is not already marked.
k. Cut the ring terminals off each of the two wires (P54A10 and P54A10N) and strip the insulation 0.5 inch from each
end of the two wires.
I. Remove the wires from the grommet in the mounting plate but do not lose the identity of the wires. If needed,
reinstall the terminal covers on the wires after removing the wires from the grommet. Remove the grommet.
5. INSTALLATION OF INVERTER. (Roof Removed).
a. Drill four holes, (9/32 or 5/16 diameter) in the inverter mounting tray, item (15), figure 1 as shown in figure 2,
Mounting Plate Hole Location-Top View. Measure 3.0 inches from the AGPU wall and .75 inches from the right edge of
the mounting plate. The holes are shown in figure 2 as A, B, C, D.
b. Ensure that the ON/OFF switch on the PROWATT800 inverter is in the OFF position.
c. Connect the positive white wire P54A10 to the red positive terminal (+). Insert the bare end of the wire into the
terminal and tighten the screw to damp the wire securely.
d. Connect the negative white wire P54A1 ON to the white negative (-) terminal on the new inverter. Connect the
new 3 in. long wire (P56A8N) to the white negative terminal. Tighten the screw to damp the two wires securely.
e. Verify that the black terminal cover is on the wire connected to the negative white terminal on the new inverter.
Verify that the red terminal cover is on the wire connected to the positive (+) red terminal on the new inverter. The
terminal covers can now be cut off the two wires if the wiring is correct
