Power supply
Infeed points
You supply the PDC at the logic unit (1L+, 2L+) and power unit (4L+) infeed points with the
following voltages:

Power unit
24 to 48 V DC
4L+
When energy recovery is activated, a supply voltage above 52.8 V DC (maximum value
1)
58.8 V) is also permitted. Use a suitable bi-directional supply to ensure that the voltage at
4L+ never exceeds 60 V DC during operation or under fault conditions.
It is essential that you observe the information on recovery in the section "Energy
recovery" in the System Manual SIMATIC MICRO-DRIVE Drive controller PDC
support.industry.siemens.com/cs/ww/en/view/109797859).
Use separate power supply units to supply the logic unit and the power unit or a filter between
the shared power supply unit and the power supply.
NOTICE
If you are using SELV/PELV with a common negative pole for the supply of 1L+ and 4L+, you
must insert a two-pole miniature circuit breaker (2P, 240 V AC, tripping characteristic C, rated
current 3 A, EN 60947-2) according to UL category DIVQ (UL 498) in the supply line to 1M/1L+.
You can find the article numbers of the miniature circuit breakers to be used in the section
"Accessories/Spare parts" in the System Manual SIMATIC MICRO-DRIVE Drive controller PDC
(https://support.industry.siemens.com/cs/ww/en/view/109797859).
