Danger of death by high electrical voltage.
DANGER
●
Connect power supply units, which generate protective extra-low voltage
(PELV) (24 V), only to supply voltages for which the power supply units are
designed. Comply with the overvoltage categories, see fig. 10-15 "Wiring 230
V" on page 33

PE bars are to be installed preferably on the mounting plate. In case of isolated PE bars,
connect both ends 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 mains cable.
