4.3.1 Protected Earth (PE)
The Protective Earth (PE) on the
busbar connection is a bolt and
nut, size M10. Colour code:
green/yellow. The equipotential
connection, connecting the metal
frame, is provided at the top of the
supply cabling compartment. This
connection is already wired to the
busbar PE. An additional PE
connection is provided on the
cabinet’s bottom of the supply
compartment. All necessary nuts
and washers are included.
4.4 Connecting power supply cables.
Supply cables can be wired in
parallel, whilst each of these
cables must contain the three
phases and the Neutral under the
same sleeve. This cable must be
protected in the switchboard. The
total size of the conductors must
be chosen depending on the total
power of the dimmers, the utility
factor, the general protection on
the supply side, the voltage drop in
the line and local regulations. We
suggest the use of several cables
placed in parallel, to facilitate the
work of the contractor: the cables
usually have a bending radius of
min. 15 times their external
diameter. Respect an angle of 30
degree to connect the supply cable
in order to achieve necessary
distance between the cables and
busbar. Use the wholes on bottom
and top to connect the cable wraps
for stress relief.
