Siemens SCALANCE W1780 Configuration Manual page 27

A Siemens power insert can also be used as the interface for the power input. Since a power
insert supports a power supply of 24 VDC, it does not conform with 802.3af or IEEE 802.3at.
The following restrictions relating to the use of power inserts should be noted:
Operate the power insert only when the following conditions apply:
● with extra low voltages SELV, PELV complying with IEC 60364-4-41
● in USA/CAN with power supplies complying with NEC class 2
● in USA/CAN, the cabling must meet the requirements of NEC/CEC
● Power load maximum 0.5 A.
