8.5 24V Power Supply Voltage (X100)
DANGER
The EPPC-T10 may only be driven by power supply current circuits, that are contact
protected. A power supply, that provides a safety extra-low voltage (SELV) according to EN
60950-1, complies with this conditions.
The power supply voltage is connected via the Phoenix Contact connector plug - MC 1,5/ 3-STF-
3.81 with screw-connection, which is located in the bottom side of the case.
For Conductor Connection/Conductor Cross Sections see the following chapter.
