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 cables, 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.
Exclusively connect a supply voltage that corresponds to the type
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
Install a suitable input fuse in the following cases:
The neutral conductor or the negative terminal of the supply voltage
is ungrounded.
For the supply voltage, you provide a DC voltage greater than
125 V DC.
See “General technical data” on page 64.
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.
