Supply voltage for PoE power supply units (optional)
Connect the protective conductor with the ground screw before you
set up the other connections. When removing the connections, you
remove the protective conductor last.
Make sure that the cross-section of the protective conductor cable is
the same size as or bigger than the cross-section of the voltage supply
cables.
Only use connection cables that are permitted for the specified
temperature range.
Shielding ground
Note:
The shield ground wire of the twisted pair lines is connected to the
front panel as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shielding braiding.
WARNING
ELECTRIC SHOCK
Only connect a supply voltage as described in the data plate of your device.
PoE power supply unit RPS90/48V LV:18 V DC to 60 V DC
PoE power supply unit RPS90/48V HV:48 V DC to 320 V DC or 90 V AC
to 265 V AC
- If the neutral conductor or the negative terminal of the supply voltage is not
grounded
- If you are using a DC voltage greater than 125 V DC for the supply voltage
install a suitable input fuse.
For RPS90/48V-LV power supply units, use a slow-blow fuse with a nominal
rating of 10 A for the voltage supply input.
For RPS90/48V-HV power supply units, use a slow-blow fuse with a
nominal rating of 6.3 A.
With AC power supply, use a cable cross-section of at least 0.75 mm² (for
North America AWG 18) for the current conductor at the voltage input.
With DC power supply, use a cable cross-section of at least 1.0 mm² (for
North America AWG 16) for the current conductor at the voltage input.
Failure to follow these instructions can result in death, serious injury,
or equipment damage.
