Strip each wire, exposing 12 mm of copper on each. If
the cable has flexible conductors, then you must use
ferrules on stranded wires to make the connection.
Use the correct tools to press them.
Tighten the screw terminals with a torque of 5 Nm.
NOTES
— When connecting multiple backplates in parallel,
each screw terminal serves as a coupling point
for adjacent backplates. All backplates must be
connected with the same phase sequence. External
junction boxes or flat cables can be used if it is more
convenient.
— It's recommended to follow the existing colour codes
used in the installation. Depending on national
standards, the colours of the cables can vary from
the illustrations. The illustrations in this manual
follow the IEC 60446 standard.
— Before turning on the power, make sure the wires are
properly connected and tightened.
