Where This Kit is Used You can use this kit to install a snubber board on the SCR moduleyour drive.

What This Kit Contains This kit contains a snubber board assembly and these instructionsSCR module testing and replacement information is included in theinstructions.

How to Use These Instructions To install a snubber board on your drive:

1. Determine the rating of the drive, refer to “Drive and OptionIdentification” on page I-7.

2. Access the SCR module, refer to “SCR Module Access” onpage I-11.

3. Install the snubber board, refer to “Snubber Board Installation”on page I-22.

If your drive is not working correctly, refer to “SCR Module Test” onpage I-24.

Safety Precautions

!ATTENTION: Some printed circuit boards and drivecomponents may contain hazardous voltage levels.Remove and lock out power before you disconnect orreconnect wires, and before you remove or replace fuseand circuit boards. Verify bus voltage by measuring thevoltage between +DC and -DC on Terminal Block TB1.Do not attempt to service the drive until the bus voltagehas discharged to zero volts.

!ATTENTION: Potentially fatal voltages may resultfrom improper usage of oscilloscope and other testequipment. The oscilloscope chassis may be at apotentially fatal voltage if not properly grounded. If anoscilloscope is used to measure high voltage waveformuse only a dual channel oscilloscope in the differentiamode with X 100 probes. It is recommended that theoscilloscope be used in the A minus B Quasi-differentiamode with the oscilloscope chassis correctly groundeto an earth ground.

Electrostatic Discharge Precautions

Electrostatic discharge generated by static electricity can damagecomplimentary metallic oxide semiconductor devices on variousdrive boards. It is recommended that you perform these procedureguard against this type of damage when circuit boards are removeinstalled:

• Wear a wrist-type grounding strap that is grounded to the drivechassis.

• Attach the wrist strap before removing the new circuit board frothe conductive packet.

• Remove boards from the drive and immediately insert them inttheir conductive packets.

Torque Sequence When mounting components to a drive’s heat sink,component-fastener torque sequences and tolerances are crucialcomponent-to-heat sink heat dissipation.

The following illustrates temporary and final tightening sequences fcomponents fastened to a heat sink using two, four, and six screwTemporary torque is 1/4 (25%) of final torque. The numericillustration labels are for your assistance. Drive components do nocarry these labels.

!ATTENTION: This assembly contains parts and subassemblies that are sensitive to electrostatic dischargStatic control precautions are required when servicingthis assembly. Component damage may result if youignore electrostatic discharge control procedures. If yoare not familiar with static control procedures, referenceAllen-Bradley Publication 8000-4.5.2, GuardingAgainst Electrostatic Damage, or any other applicableESD protection handbook.

!ATTENTION: Component can be damaged iftemporary tightening procedure is not performed tospecification.

1. Access the SCR Module. Refer to “SCR Module Access” onpage I-11.

2. Set your meter to test diodes.

3. The following table shows meter connections and ideal meterreadings for those connections. Refer to Figure I-11 for meterconnection locations.

Note: Typical malfunction is shorted in both directions.

Note: Meter Used: Fluke® Model 87, set to “Diode” range.

4. Replace the SCR Module if any meter readings are not as shoRefer to “SCR Module Replacement” on page I-26.

5. If the SCR Module shorted, check the IGBT for damage.

Important: Refer to your Service or Troubleshooting Manual forIGBT Module test information.

Assemble the drive in reverse order of removal. Refer to “TorqueSequence” on page I-4. Refer to “Torque Specifications” on page I-for final tightening.
