Outgoing Motor Cable Connections
When the Junction cabinet is not applied, the outgoing motor cables connect
to the cable stand-off assembly on the cabinet side sheet or the cable stand-off
that is mounted on the Isolation Transformer, depending on the different
configuration or drive rating.
When the Junction cabinet is applied, the outgoing motor cables connect to the
terminals inside the Junction cabinet. Outgoing motor cables can be routed
inside through the top or bottom of the cabinet system. Generous working
space is provided. See the PowerFlex 6000 Medium Voltage Variable
Frequency Drive Installation Instructions, publication
for
additional details.
Door Position Limit Switch
Each cabinet door that allows access to medium voltage components is
lockable and also has a Guardmaster® safety limit switch. If the cabinet door is
opened when the input switching device feeding power to the drive is closed,
the input device is tripped off.

ATTENTION:
The door position interlock is a safety feature. It must not be
used solely as a part of the plant operation process to verify that the drive has
been disconnected from input medium voltage. Keep the medium voltage
doors locked as standard practice. If access to the medium voltage rated
cabinets is required, always go to the input device feeding the drive to verify
if it is open. Lock out and tagout the input device before performing any work
on the drive or bypass units.
