it may cause electric shock, mal-function or even damage to the AC drive.
– Do not connect this terminal to the neutral conductor of the power supply.
– The impedance of the PE conductor must be able to withstand the large short-
circuit current that may arise when a fault occurs.
– Select the size of the PE conductor according to the following table:

– You must use a yellow/green cable as the PE conductor.
7) Requirements on upstream protection device
– Install a proper protection device on the power input side to provide protections on
overcurrent, short-circuit and electrical solation.
