Power supply (Power)
Power supply either
• at terminals 7 and 8 (AC/DC)
• or at terminals 1 and 2 (24 VDC).
The supply voltage must be protected by external measures.
The terminals of the DC supply are directly linked with the terminals of the sensor
supply. This is why the SELV criteria must be adhered to for DC supply (protective low
voltage, circuit galvanically separated from other circuits, not earthed).
If the DC circuit is to be earthed (e.g. because of national regulations), the PELV cri-
teria have to be adhered to (protective low voltage, circuit galvanically separated
from other circuits).
If the unit is supplied with AC voltage, the low voltage supply for the sensors meets
the SELV criteria.
The device shall be supplied from an isolating source and protected by an overcur-
rent device such that the limited voltage circuit requirements in accordance with UL
508 are met.
