PE bars are to be installed preferably on the mounting plate.
In case of isolated PB bars, both ends must be connected to the mounting plate
by means of copper strips with a maximum length of 20 cm.
The cross-section of the copper strips has to be at least equal to that of the incoming cable.

Danger of death by high electric voltage
DANGER
●
Connect power supply units, which generate protective extra-low voltage
(PELV) (24 V), only to supply voltages for which they are designed. Do
observe the overvoltage categories, see also
●
Do not apply the supply voltage to the protective extra-low voltage (PELV).
