Use of side-connector at ctrlX DRIVE?

What's the use of the side-connector at the amplifiers?

You are talking about the XE20 connector? 
This plug is used to disconnect the drive internal suppressor capacitors (Y-capacitors) between the DC-link and ground. When connecting the ctrlX DRIVE to an IT network or at a IndraDrive ML system, the suppressor capacitors (Y-capacitors) must be removed. Further information will follow.
