NOTICE
We recommend using solid (single-core) wires. If stranded
wires are used, slightly twist the strands to consolidate the
end of the conductor for either direct use in the terminal
clamp or insertion in a round crimp-style terminal. Details
are described in "Guidelines when connecting the electrical
wiring" in the installer reference guide.
