Assembly:
DC20/60/110 circuit breaker/disco connects are installed
adjacent to the DC175/250 breakers on the right side panel for SW
systems and on the left side panel for DR systems. Begin the installation
by removing the topmost nut and one flat washer on the back of the circuit
breaker and install the barrel lug over the stud. Replace the flat washer
followed by the starwasher and the nut, then tighten. Insert the breaker in
the side panel from the inside and secure with two 6-32 x 3/8” machine
screws with #6 internal tooth starwashers. When used with the C40
charge controller, connect the C40 Battery (+) terminal to the bottom of the
DCXX and your PV array positive to the barrel lug at the top of the DCXX
to complete the installation. When a charge controller is not used, connect
your PV positive to the top of the breaker, and route a 6 AWG
cable from the bottom of the DCXX to the top of your
DC175/250 breaker.
Tools Required: ¼”, 7/16” & 3/8” socket or wrench; #2
flat-blade screwdriver; wire stripper, crimping tool.
