NOTE
Damage to the Embedded PCs
The Embedded PCs may be damaged during wiring.
• The cables for the power supply should only be connected in de-energized state.
The CX2100-0004 power supply units require an external voltage source, which provides 24VDC (-15% /
+20%).
The cabling of the Embedded PC in the control cabinet must be done in accordance with the standard EN
60204-1:2006 PELV = Protective Extra Low Voltage:
• The "PE" and "0V" conductors of the voltage source for a basic CPU module must be on the same
potential (connected in the control cabinet).
• Standard EN 60204-1:2006, section 6.4.1:b stipulates that one side of the circuit, or a point of the
energy source for this circuit must be connected to the protective earth conductor system.

NOTE
Interrupting / switching off the power supply
To switch off the Embedded PC, do not disconnect the ground (0 V), because otherwise current may con-
tinue to flow via the shielding, depending on the device, and damage the Embedded PC or peripheral de-
vices.
• Always disconnect the 24 V line. Devices connected to the Embedded PC, which have their own power
supply (e.g. a Panel) must have the same potential for "PE" and "0 V" as the Embedded PC have (no
potential difference).
