Chapter 1 Introduction
MS300
(High Speed Model)
1-4
1-4 RFI Jumper
(1) In the drive there are Varistor / MOVs, which are connected from phase to phase and from phase to
ground, to protect the drive against mains surges or voltage spikes.
Because the Varistors / MOVs from phase to ground are connected to ground via the RFI jumper, the
protection will be ineffective when the RFI jumper is removed.
(2) In the models with built-in EMC filter the RFI jumper connects the filer capacitors to ground to form a
return path for high frequency noise to isolate the noise from contaminating the mains power.
Removing the RFI jumper strongly reduces the effect of the built-in EMC filter.
(3) Although a single drive complies with the international standards for leakage current, an installation
with several drives with built-in EMC filter can trigger the RCD. Removing the RFI jumper helps, but
the EMC performance of each drive would is no longer guaranteed.
Frame B~F Screw Torque:
4~6 kg-cm / [3.5~5.2 lb-in.] / [0.39~0.59 Nm]
Loosen the screw and remove the RFI Jumper (as shown below). Fasten the screw again after the RFI
Jumper is removed.
Frame B~F (model with built-in EMC filter)
Remove the RFI Jumper with a screwdriver (as shown below).
