2.1.3 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.
2.1.4
Connecting power supply cables.
Supply cables can be wired in
parallel, while 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.
2.1.5
Earthing
The sound or video earth should be separated from the dimmer earth. The distance
between the dimmer earth and the others should be as large as possible. Refer to local
regulations for earthing.
