Voltage Sensing Modules
● When used for the infeed control, the Voltage Sensing Module (VSM) should be
connected to DRIVE-CLiQ socket X202 (booksize format) or X402 (chassis format) of the
associated Line Module.

Terminal Modules
● Terminal Modules should be connected to DRIVE-CLiQ socket X103 of the Control Unit in
series.
● If possible, Terminal Modules should not be connected to the DRIVE-CLiQ line of Motor
Modules, but rather to free DRIVE-CLiQ sockets of the Control Unit.
Note
This restriction does not apply to star-type connections for the Motor Modules.
