Fiber-optic Connections
Fiber-optic cables are routed and connected at the factory in frame 8 and 9 drives and frame 8…10 bus supplies. These cables connect the fiber interface circuit board to the line side converters and motor side inverters in the adjacent enclosures.
IMPORTANT:
Do not remove protective covers from unused wire harnesses, circuit board connectors, terminal blocks, and fiber-optic ports. Removing a protective cover can lead to contamination.
Control Pod to Power Module Connections
Fiber-optic cables at the control pod plug into transceiver modules that are mounted to a
transceiver board. Transceiver boards plug into an edge connector on the fiber interface
board. Inspect these connections at installation. Re-seating these connections after
shipping and handling or after extended storage is recommended.
Item | Description |
|---|---|
A | Transceiver boards plug into the fiber interface board. Verify that these
connections are secure. |
B | Fiber-optic cables routed from the control pod plug into the CTL transceiver
cages that are mounted on the power layer interface boards located behind the
power module access panel. |
C | Fully insert fiber-optic cable plugs into the transceiver. Insert the
transceiver into the connector cage on the power layer interface board until you
hear it click into place. |
D | Remove protective covers only as needed to help maintain corrosive gas
protection. |
E | Do not touch the greased connector to help avoid contamination. |
F | Fully insert fiber-optic cable plugs into the transceiver. Insert the
transceiver into the connector cage on the transceiver board until you hear it
click into place. |
G | Power module. |
Fiber-optic Interface Board
The fiber-optic interface board holds the fiber transceiver circuit boards.
Fiber-optic Transceiver Circuit Board Connections
Port Name | Description |
|---|---|
ACP0 | Fiber transceiver port for the fiber-optic connection from ACP0 on the AC precharge control board. |
ACP1/TAM | Fiber transceiver port for the fiber-optic connection from ACP1 (frame 13 and larger) or TAM on the torque accuracy module. |
L0…L9 | Fiber transceiver ports for the fiber-optic connections from CTL on the power layer interface board in power modules that are used as line side converters. |
M0…M9 | Fiber transceiver ports for the fiber-optic connections from CTL on the power layer interface board in power modules that are used as motor side inverters. |
Each fiber-optic cable connects to its designated CTL port on the power module power layer interface circuit board.

|---|---|
A | Shipping split location. |
B | Fiber-optic interface board connections. |
C | L0-CTL and L1-CTL connections are made at the factory. |
D | L2-CTL…L9-CTL connections. |
E | M0-CTL…M9-CTL connections. |
Fiber-optic cables are routed between cabinets through the power control channel. Cable guides are provided to help you keep the cables separated and organized.
Power Control Channel and Cable Guides
Item | Description |
|---|---|
A | Typical fiber-optic cable routing through the power control channel between cabinets. |
B | Use cable guides to organize cable runs. |
Cables are routed to the right-to-left oriented cabinets through the pass-through grommet that connects the wire bays in back-to-back configurations.
Fiber-optic Cable Routing Between Back-to-Back Entry Wire Bays
Item | Description |
|---|---|
A | Back-to-back configured entry wire bays. |
B | Pass-through grommet. |
C | Power control cable channels. |
D | Cable tie anchor points help to keep cables in place. |
Cables are routed out of the power control channel and are plugged into the CTL transceiver port of the corresponding power module.
This image shows an 800 mm (31.5 in.) wide converter power bay. The front panels are omitted to show the proper cable path to the CTL transceiver port on the power layer interface board.
