7.3 Mixed operation
You can combine the PS6 supply module and SI6 drive controller with other drive controllers
from the 6th generation of STOBER drive controllers.
For UL-compliant operation, note that mixed operation is not currently possible.
In mixed operation, only device types of the same series and size may be supplied with power.
The framework conditions for the supplying device apply.
The graphic below shows an example of the grounding concept in mixed operation with a
powered PS6 supply module. The protective connection between the supply module or drive
controller and the associated Quick DC-Link rear section module (type DL6B or DL6A) is made
using the metallic connection of the housings. The protective connection between the rear
section modules of the DL6B type is made using a copper rail. You can find the requirements
for the connection of a 2nd grounding conductor for a supply module in the chapter CE-
compliant housing grounding [}107]. The same requirements also apply to drive controllers with
DL6A rear section modules.
