Checking wiring

To check the correct wiring, measure the resistance and loop resistance on the devices in the main distribution
unit and in all external sub-distribution units. Enter the measured values in the Actual value column. Also check
for external voltages and eliminate these.
Note
i
Carry out the measurement when the eBox system is free of voltage.
