1. Slide the cable inside the grommets, ensure at least 10mm of cable external jacket inside the box (see notes at
the end of this section, before sliding the cable inside the grommet. Allow at least 24 inches of wire from the
conduit entry point to allow enough wire to route thru the internal grommet/cable glands and wrap around to
the terminal blocks. (For the 3-phase version, remember to route the wires thru the ferrite)
2. Push the cables back through the gland plate, until sufficient cable length is left to reach the cable terminals.
Ensure the PE cable is longer than the other cables.

NOTE 1: For 3-phase versions a ferrite core is provided with the Wallbox (plastic bag within the package or strapped to
the CCS-1 cable) and needs to be installed in commissioning phase. The Ferrite needs to be inserted in the AC in cable
and located in the screw cable cover (see picture above, left).
THE FERRITE IS REQUIRED TO MAINTAIN THE
WARRANTY.
NOTE 2: Two floating grounding cables are provided that are connected to the ground node. One cable must be con-
nected between the to the wall frame PEM the other to the front lower cover in order to guarantee equal ground po-
tential (see picture above, right).
