Connections for voltage-carrying lines
Note:
The supply voltage is electrically isolated from the housing.
A device has two internal power supply units. Each power supply unit has a
connection for the supply voltage and a connection for the alarm relay contact.
The power supply unit types have the following different properties:
Type of connectable supply voltages: DC voltage
Level of connectable supply voltages:
The following tables provide an overview of the possible connections for
voltage-carrying lines:
