Voltage supply of a multifunction panel 840
CAUTION!
Long connecting cables can cause a significant voltage drop at high current load (max. 8 A).
This may lead to an underflow of the minimum allowable input voltage of DC 19.2 V.
To prevent this, the output voltage of the power supply has to be increased if possible. Hereby
it is important to ensure that the maximum allowable input voltage of DC 30 V is not exceeded
at any module.

NOTE!
Only use the installation instructions or the operating manual of the multifunction panel 840
for the electrical connection. Follow the safety information stated there.
