Selecting the power unit
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 packs
which guarantee reliable electri-
cal 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 CPI/CP system depends on the
number of CPI/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.
