3.3.3.5 DC Connection for Standard and RSD Wirebox
1. Using the 1-1/2 inch openings. Remove the factory installed liquid-tight
hole plugs from the DC knockout holes in the wiring box and install 1-1/2
inch Trade Size conduit and conduit fittings. If the use of smaller conduit is
desired, proper weather-tight reducing bushings may be installed. Confirm
all fittings are NEMA 4X rated, properly tightened, and route the DC
source circuit conductors through the conduit into the wiring box.
2. Refer to the connection method of standard wiring box. The RSD
transmitter sends the powerline communications (PLC) signal through the
negative conductors via the busbar. AC power to the inverter is required in
order to turn on the transmitter and signal the array.
