Example:
Faulty contacting of the sliding contact can result in a connection between the system supply
(L1/L2/L3) and the communication cables (Rail A/B). The communication lines will then carry
a voltage of 230 V to ground, for example. These 230 V are then the rated voltage for the
basic isolation of the filter, the PLBs as well as additional components connected to the
communication cables.

2.7.2
PLB connection cable
The connection cables in a powerline system have a strong impact on the signal attenuation
and cause poles in the frequency range used. This is why the selection of cables also has an
effect on the maximum configuration limit. For details on this, see section "Maximum number
of stations (Page 40)".
It is generally true that all cables in the system must be of identical length so that the poles
are located in the same frequency range. However, it is permissible to use a different cable
length for the master than for the cables between PLB slave and the sliders.
For cable lengths of ≤ 1
meter, there are no specific requirements on the cable or shielding
except for the electrical specifications (e.g. rated voltage 230 V).
