Beckhoff EP1 Series - Power Cable Conductor Losses M8

Mounting and cabling
EP1xxx 53Version: 2.5.0
3.3.3 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.
Note
