Remove the factory installed liquid-tight plugs from the DC knockout holes in the Wire Box and install 1-1/2 inch
Trade Size conduit and conduit fittings. If the use of smaller conduit is desired, use proper weather-tight reducing
bushings to ensure the Wire Box maintains its NEMA 4X rating. If larger conduit than 1-1/2 inch is required, either
use reducers or create larger concentric holes from the knockout holes provided. However, care must be taken to
ensure that water tight seals can be made with the larger knockouts. No new holes in unspecified areas are
allowed or it will impact the NEMA 4X rating and wire box warranty. Confirm all fittings are properly tightened
and route the DC source circuit conductors through the conduit into the Wire Box.

Rapid Shutdown: 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.
Strip approximately 1/2 inch of the cable jacket from the end of the source circuit conductor. Insert the conductor
into the fuse holder terminal ensuring the stranding of the conductor remains firmly twisted and does not
separate. Tighten the screw clamp to the torque specified in Table 3-7. Continue terminating the remaining
source circuits in this manner for each MPPT zone (PVIn1, PVIn2, PVIn3).
