If a PowerFlex 20-750-PBUS Profibus option module resides in the adjacent port
to the right of the port in which the new module is being installed, the lower T15
Torx™ head mounting screw (see Detail A) of the new module may electrically
contact the metal Profibus cable connector attached to the Profibus option
module. This may cause faulty operation. To help prevent this, perform the steps
below. If a PowerFlex 20-750-PBUS Profibus option module is not in that port,
disregard these steps.
1. Remove the lower T15 Torx head mounting screw shown in Detail A,
from the new module being installed.
To remove the captive T15 Torx head screw, the module must be removed
to back the screw out of the mounting clip.
2. Replace the larger T15 Torx head screw with the smaller spare T8 Torx
head mounting screw that was shipped with the PowerFlex 20-750-PBUS
Profibus option module.
