Warning
In order to provide the electric power supply, use only
·
PELV circuits as per IEC/DIN EN 60204−1 (Protective
Extra−Low Voltage, PELV).
Take into account also the general requirements for
PELV circuits as per IEC/DIN EN 60204−1.
Use only power packswhich guarantee reliable electrical
·
isolation of the operating voltage as per IEC/DIN
EN 60204−1.
By the use of PELV power units, protection against electric
shock (protection against direct and indirect contact) is
guaranteed in accordance with IEC/DIN EN 60204−1
(electrical equipment of machines, general requirements).
The current requirement of a CP system depends on the
number of CP modules and valve coils.
Recommendation:
Use closed−loop controlled power units.
·
When selecting the power unit, check that it provides
·
sufficient output. If necessary, calculate the total current
requirement according to the following table.
