onitron’s M3460RD Impedance Modules are designed to offer system integrators a low
cost solution for using an M3460R Ride-Thru Module (RTM) in systems where there is an
AC input directly to the M3460R module. In some installations, additional impedance in
the negative DC link may be required for proper operation. The M3460RD prevents
circulating currents between the variable frequency drive and the M3460R Ride Thru
Module.
Please see the Application Notes in Section 7 for additional information.

The maximum current rating of the M3460R Ride Thru module is designated by this
value in amperes. M3460R Ride-Thru modules rated 85A-255A should use
255 .
M3460R Ride-Thru modules rated 340A-425A should use 425 .
