AC Line Choke 
We recommend that you always use the specified ac line choke with the Drive 
to provide a known supply impedance for effective operation of the thyristor transient suppression circuits. At least 1% line impedance should be 
provided in the supply side of the drive.  
Refer to Appendix E: “Technical Specifications” - AC Line Choke for selection details.
