3.2 Power supply
Warning
· Use only PELV circuits as per IEC/DIN EN 60204−1 for
the electric power supply (protective extra−low voltage,
PELV).
Take into account also the general requirements for
PELV circuits as per IEC/DIN ENĂ60204−1.
· Use only power supply units that guarantee reliable
electrical isolation of the operating voltage as per
IEC/DIN EN 60204−1.
Protection against electric shock (protection against direct
and indirect contact) is guaranteed in accordance with
IEC/DIN EN 60204−1 by using PELV circuits (electrical equipĆ
ment of machines, general requirements).
Note
Note that the tolerances of the voltage supply must also be
observed directly at the voltage supply connection of the
SFC−LACI.
· For the power supply, use only the cables specified in
Tab. 3/2.
· Use closed−loop regulated power supply units that
comply with the requirements described in Tab. 3/4.
Load voltage supply: The use of power supply units with
lower output levels is possible with restricted motion dyĆ
namics and loads. To do this, you need to enter the power
output of your power supply unit into the FCT (or via the CI
object 6510/50h).
