NOTICE
Inadmissible equalization currents as a result of potential differences when using different
power supply sources
Using different power sources for the Heat Exchanger Module and the other Cabinet
Modules can result in potential differences and inadmissible equalizing currents flowing
through the DRIVE-CLiQ interface of the TM31 Terminal Module.
• For the external 24 V DC power supply of the control box, use the same power supply
