3. If the Rapid Shutdown Controller conductors are laid in the same conduit as the output strings,
pull off the adhesive tape on the enclosure opening.
4. Insert the conduit fitting into the opening on the Rapid Shutdown Box and tighten from the
inside using the counter nut.
5. Attach the conduit at the conduit fitting in the Rapid Shutdown Box enclosure.
6. Lead the conductors up to the terminal block RSC in the Rapid Shutdown Box.
7. Lead a silicone tube over the conductors inside
the Rapid Shutdown Box.
8. Strip off the conductor insulation by 8 mm (0.31 in).
9. In the case of fine stranded wire, provide each conductor with a bootlace ferrule.
10. Connect the conductors to a five-pole plug.
Observe the pin assignment.
11. Place the cable tie onto the silicone tube, tighten
and cut off the projecting end of the cable tie.
This connects the conductors and the silicone
tube together securely.
12. Plug the five-pole plug with the connected
conductors into the lower pin row of the terminal
block RSC.
13. If there is only one Rapid Shutdown Box in the
system, plug the second five-pole plug into the
upper row of the terminal block RSC and place
a jumper wire between pins 3 and 4. Here, use
a jumper wire that is rated for the maximum
system voltages or insulate the jumper wire using
a piece of one of the supplied silicone tubes.
