Network Communication Option Module
(for use with PowerFlex

ATTENTION: Risk of injury or death exists. The PowerFlex
750-Series drive may contain high voltages that can cause injury or
death. Remove power from the drive, and then verify power has been
discharged before removing the drive cover.

ATTENTION: Risk of equipment damage exists. The network
communication option module contains electrostatic discharge (ESD)
sensitive parts that can be damaged if you do not follow ESD control
procedures. Static control precautions are required when handling the
card. If you are unfamiliar with static control procedures, see Guarding
Against Electrostatic Damage, publication 8000-4.5.2.

Important: For the PowerFlex 20-750-PBUS Profibus option module, disregard

these instructions. Instead, see its User Manual, publication
750COM-UM004, for special installation instructions.

DETAIL A

➍

Important: 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—and the lower mounting screw of
the new module is a T15 Torx head screw (shown in DETAIL
A above)—that screw may electrically contact the metal
Profibus cable connector attached to the Profibus option
module. This may cause faulty operation. To prevent this,
perform steps 4-A through 4-C below. If a PowerFlex
20-750-PBUS Profibus option module is not in that port,
disregard these steps and proceed to step 5.

A. Remove the lower mounting screw, a T15 Torx head screw shown in

DETAIL A above, from the new module being installed.

3

B. 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.

C. Proceed to step 5.

TIP: To remove the captive T15 Torx head screw, the module must

be removed to back the screw out of the mounting clip.

➎

Tighten both of the option module mounting screws to the pod mounting
bracket to properly ground the module to the drive. Tighten both screws to
the recommended torque shown below.
