7.3 Electric cables
Conductor cross sections
When determining cable cross-sections, the loss of voltage in
the conductors must be considered. If the voltage drop is too
great, it may lead to the conductors becoming heated and, under
certain circumstances, to a cable fire. Conductor cross-sections
of less than 18AWG / 1 mm
stability of the conductor. The positive and negative cables must
have the same cross-section. Technical literature provides in-
formation regarding the cross-sections of electric conductors that
are to be used or which are suitable. No more than 5 A should
be carried per mm² cable cross-section.
The necessary cross-section must be calculated by the im-
plement manufacturer and must be tested under concrete,
practical conditions.
For extending electric cables, note the following:
•
Only use cables with the same cross-section and same
basic and identification color as the standard cables.
•
The cables must be sheathed with a protective insulating
sleeve to prevent chafing and abrasion.
•
Only attach original connectors or connectors of equiva-
lent quality to the cable end.
•
Electric cables may only be connected via junction
boxes.

are to be avoided due to the low
•
Do not change standard connections, e.g. ground con-
nections.
•
When changing the length of cables or installing further
cables, waterproofed connectors must be used.
•
If the installation position of electric or electronic compo-
nents is changed, the length of the electric cable must be
adapted. Routing may compensate for slight excess in
the cable length. Excess length must not be routed in
rings or loops.
When routing cables from one side of the frame to the other, use
existing holes. An additional hole may only be drilled if there is
no other possibility for passing the cable through the frame. Re-
ferring to section 10.6 Mounting of implements on page 275. The
hole must be provided with edge protection (grommet), so that
the cables are protected against damage.
