Rockwell Automation 7000 PowerFlex Medium Voltage AC Drive (B Frame) - Classic Control - Manual (Page 78)

Drive Installation 2-43
7000 “B” Frame 7000-UM150I-EN-P – June 2013
Interlocking
Access to the medium voltage areas of the drive is restricted by the
use of key interlocking for safety.
At installation the key interlocking is set up so that access to the
medium voltage compartments of the equipment can only be made
when the upstream power is locked in the off position.
Additionally, the key interlocking prohibits the upstream power
being applied until the medium voltage drive’s access doors have
been closed and locked shut.
It is the responsibility of the installer to ensure that the key
interlocking is installed properly to the upstream equipment.
