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 EN60204−1.
· 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 agai
nst direct
and indirect contact) is guaranteed in accordance with
IEC/DIN EN 60204−1 by using PELV circuits (electrical
equipment of machines, general r
equirements).
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
dynamics 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).
