Warning
Use only PELV circuits as per IEC/DIN EN 60204−1 (Pro
·
tective Extra−Low Voltage, PELV) for the electrical supply.
Consider also the general requirements for PELV circuits
in accordance with IEC/DIN EN 60204−1.
Use power supplies which guarantee reliable electrical
·
isolation of the operating voltage as per IEC/DIN EN
60204−1.
By the use of PELV circuits, protection against electric shock
(protection against direct and indirect contact) is guaranteed
in accordance with IEC/EN 60204−1 (Electrical equipment for
machines, General requirements).
The current consumption of a CP system depends on the
number of CP modules and valve coils. Recommendation:
Used closed−loop power units.
