Power supply

The device has an internal fuse and protection against polarity reversal. The functional earth is
connected to the connector cover only, and not to 0 V.
The housing is made of plastic and is potential-free. The device's power supply is not galvanically
isolated.
The device requires a power supply of 24 V DC from an AC/DC transformer with safe isolation (SELV).
Additional properties of the required power supply, see chapter 9.5.1 Power supply,  73.
SELV (safety extra low voltage):

Circuit in which no dangerous voltage is present, even in the event of a single fault.
