5. Route the option wiring.
Depending on the drive model, some drives may require routing the wiring through the side of the front cover to
the outside to provide adequate space for the wiring. Refer to the Peripheral Devices & Options section of the
drive Quick Start Guide or instruction manual for more information on wire routing of specific models.
Route the wiring through the side of the front cover to the outside. In these cases, using diagonal cutting pliers,
cut out the perforated openings on the left side of the drive front cover as shown in
Figure 7 -A. Sharp edges
along the cut out should be smoothed down with a file or sand paper to prevent any damage to the wires.
Route the wiring inside the enclosure as shown in
Figure 7 -B for drives that do not require routing through the
front cover.
Note: Separate communication cables from main circuit wiring and other electrical lines.

6. Connect the PROFINET Cat 5e communication cable to the option modular connector CN1 port 1 or port 2.
To connect the option to a network, firmly connect RJ45 8-pin Shielded Twisted Pair Cat5e cable(s) into the
option modular connector CN1. Ensure the cable end is firmly connected (see
Figure 7 ).
Note: Do not connect or disconnect the communication cable while the drive is powered up or while the drive is in operation. Failure to
comply may cause a static discharge, which will cause the option card to stop working properly. Cycle power on the drive and
option card to reestablish functionality.
