Selection of an appropriate power supply
The total current consumption of the installed modules must be smaller than the rated output
current of the power supply module.Reduce the number of modules on the base unit, if the cur
-
rent consumption is too high.
Example calculation of the total current consumption
The total current consumption is 2.42 A. The installed power supply module is able to deliver a
current of 6 A. This configuration will work without problems.
