Safety Precautions The following general precautions apply when servicing an RGU or a

drive system lineup:

Special Instructions Important: You will need to reuse parts that are removed from the

unit. Place parts, in the order removed, on a clean

surface.

ATTENTION: Only those familiar with the drive

system, the products used in the system, and the

associated machinery should plan or implement the

installation, startup, and future maintenance of the

system. Failure to comply can result in personal injury

and/or equipment damage.

ATTENTION: Verify that all sources of AC and DC

power are deenergized and locked out or tagged out in

accordance with the requirements of ANSI/NFPA 70E,

Part II.

ATTENTION: The system may contain stored energy

devices. To avoid the hazard of electrical shock, verify

that all voltage on capacitors has been discharged before

attempting to service, repair, or remove a drive system

or its components. You should only attempt the

procedures in this manual if you are qualified to do so

and are familiar with solid-state control equipment and

the safety procedures in publication NFPA 70E.

ATTENTION: When servicing any unit, do not drop

any nuts, bolts, washers, etc. inside the unit, as they may

cause a short circuit on power up.

ATTENTION: This drive system contains ESD

(Electrostatic Discharge) sensitive parts and

assemblies. Static control precautions are required

when installing, testing, or repairing this assembly.

Component damage can result if ESD control

procedures are not followed. If you are not familiar with

static control procedures, refer to Rockwell Automation

publication 8000-4.5.2, Guarding Against Electrostatic

Damage or any other applicable ESD protection

handbook.

Preliminary Steps Before replacing the hub board, shut off the power; wait five

minutes for voltage to discharge; and open the bay door to the

power structure. Check the board and the wiring for physical

damage (melted copper, burn marks, or damaged components).

Replacing the Hub Board 1. Using a meter, check the voltage across the DC bus terminals

on the power structure, then check for voltage across the

terminals and test points.

2. Put on the ESD wrist strap and connect it one of the door

latches.

3. Mark the cables and sketch the wiring on the illustration

below.

4. Disconnect TB1.

5. Carefully remove the fiber-optic cables from the board (hold-

ing by the connector, not holding by the wire).

6. Pull the board from the standoffs and place the board in an

anti-static bag.

7. Push the new board onto the mounting standoffs.

8. Carefully connect the fiber-optic cables into the appropriate

terminals. Verify the wiring, according to the diagram on the

next page.

9. Plug in TB1 and verify that the terminals are secure.

ATTENTION: If there is any voltage present,

remove the source of the voltage and check for

voltages again before proceeding to the next step.

Concluding Steps After installing the board, check for any scrap material or tools in the RGU,

and secure the bay door. Send the old board to Rockwell Automation for

repair; or dispose of the board according to your company’s procedures and

your local ordinances.
