Supply with DC voltage:
Install a fuse suitable for DC voltage in the plus conductor of the power
supply.
Connect the minus conductor to the ground potential. If the minus
conductor is not connected to the ground potential, also install an external
fuse in the minus conductor.
Regarding the properties of this fuse:
See "Technical data" on page 72.
Supply with AC voltage:
Install a fuse in the outer conductor of the power supply.
Connect the neutral conductor to the ground potential. If the neutral
conductor is not connected to the ground potential, also install an external
fuse in the neutral conductor.
Regarding the properties of this fuse:
See "Technical data" on page 72.
The power supply complies with the requirements for a safety extra-low
voltage (SELV) according to IEC 60950-1 or ES1 according to IEC/
EN 62368-1.
The power supply is potential-free. For power supply modules capable of
PoE, exclusively use a potential-free SELV power supply.
Install a fuse suitable for DC voltage in the plus conductor of the power
supply.
Regarding the properties of this fuse:
See "Technical data" on page 72.
