Connections for voltage-carrying lines
The supply voltage is electrically isolated from the casing.
A device has one or two internal power supply units. Each power supply unit
has a connection for the supply voltage and a connection for the signal
contact.
The power supply unit types have the following different properties:
Type of connections: terminal or plugged
Type of connectable supply voltages: DC or AC voltage
Level of connectable supply voltages:
For devices without PoE featuring 2 power supply units, you can connect the
supply voltage redundantly. Both inputs are uncoupled. With a non-
redundant supply of the supply voltage, the device reports the loss of a
supply voltage. You can prevent this message by applying the supply voltage
via both inputs, or by changing the configuration in the Management.
Note:
At positions 36 and 37 of the product code (see
table 1
) you find which
power supply characteristic values your device has.
The following tables provide an overview of the possible connections for
voltage-carrying lines:
