Power routing 230 V
Interfering AC voltage components such as the ones resulting from an uncon‐
trolled three-phase bridge circuit without smoothing and with a ripple factor
(see DIN 40110/10.75, section 1.2) of 5 % are allowed.
That results in the greatest absolute value of 30.2 V as upper voltage limit.
The lowest absolute value of 18.5 V is the lower voltage limit.
1.05 x 28.8 V = 30.2 V
Upper limit 28.8 V
0.866 x 30.2 V = 26.1 V
1.05 x 20.4 V = 21.4 V
Lower limit
20.4 V
0.866 x 21.4 V = 18.5 V

Overvoltage category I
(1) 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.

● Connect power supply units generating protective extra-low voltage
(PELV) (24 V) only to the supply voltages they are designed for. Comply
with the overvoltage categories (see
● Do not apply the supply voltage to the protective extra-low voltage
