Power cable conductor losses M8

The ZK2020-xxxx-yyyy power cables should not exceed the total length of 15 m at 4 A (with continuation).
When planning the cabling, note that at 24 V nominal voltage, the functionality of the module can no longer
be assured if the voltage drop reaches 6 V. Variations in the output voltage from the power supply unit must
also be taken into account.

Example
8 m power cable with 0.34 mm² cross-section has a voltage drop of 3.2 V at 4 A.
