Note: There are two screw holes on the drive for use as ground terminals. When connecting three options, two ground wires will need
to share the same drive ground terminal.
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 Technical 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. Use a file or sandpaper
to make the sharp edges along the cutout smoother 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.
