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.
