When energy recovery is activated, a supply voltage above 52.8VDC (maximum value
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 (https://
support.industry.siemens.com/cs/ww/en/view/109797859).
WARNING
Use separate power supply units to supply the logic unit and the power unit or a 󹪝lter 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 󹪝nd 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).
