Replace Q Aggregator Fuse and Connection Board
A. On the roof, open the Q Aggregator using a standard screwdriver blade on the four captured
screws on the cover.
B. Use a voltmeter or electrical tester to again verify that the main circuit coming into the box is not
energized.
C. Assuming that the Q Aggregator may still be electrified, remove the fuse protective cover by
freeing the tabs closest to the main lug. Set aside the fuse cover for future use.
D. Check for voltage across all fuse terminals. If, and only if there is no voltage at any of the
terminals in the Q Aggregator, remove and tie back the main electrical connections.
E. Remove the replacement board from packaging and insert it into the Q Aggregator, taking care to
line up with tabs and screw holes.
F. Recover the five screws removed from the original board and use these to secure the new board.
G. Reattach the six locking flag terminals to the nearest terminals on the Q Aggregator, taking care
not to invert polarity. Connections should be straight across from the bulkhead connectors.
H. Reattach the main lug connections and check that the connections are secure. Reconnect the PV
array connections.
I. With no tools or loose screws in the Q Aggregator, reactivate the PV circuit and test for voltage at
the inputs and outputs of the fuses.
J. If voltages are appropriate in all locations, turn the power off and replace the fuse cover. Torque
screws to 9.7 in-lbs. (1.1 N m).
K. Make one last check of connections and re-secure the lid on the Q Aggregator. Check the seal on
all sides for trapped debris. Remove any debris, if needed.
