You can use the bridges provided on the connecting block to
make the required interconnections as indicated in the
preceding illustrations. How to install the bridges is indicated
in the junction box cover and in the illustration below. The
bridges should not be placed immediately on top of the
connecting wires, but between the screw-head and the
clamp around the connecting wire.
Secure the cable with the strain relief and close the cover.
