Supply power available for terminals

The 40 VDC power supply required for the connected terminals is rated for the
power requirements of a typical system configuration.
The number of permissible terminals per system depends on the power require-
ments of the individual terminals. To check the power requirements refer to
for details of the average power requirements of the terminals. This check can also
be carried out automatically using the Project Manager.
The total power requirements of all connected terminals must not exceed the
power output of the power supply.
