2 Selection of ELCB
The earth leakage current of the controller is larger than 3.5 mA, requiring grounding
protection.
The controller generates DC leakage current in protective conductor. In this case, a
time-delay B-type ELCB must be used.
When the ELCB malfunction occurs, you can:
■
Use an ELCB with higher rated action current or a time-delay ELCB.
■
Reduce the carrier frequency.
■
Shorten the length of the motor drive cables.
■
Install a current leakage suppression device.
■
Use Chint Electric and Schneider brands.
3.2.2 Selection Guide of AC Input Reactor
An AC input reactor is installed to eliminate the harmonic current on the input side. As
an optional device, the reactor can be installed externally to meet strict requirements
of an application environment for harmonics. The recommended AC input reactor
manufacturer and models are listed in the following table.
