I-56 1336-5.39 – August, 1999 I-3 Where This Kit is Used You can use this kit to install a snubber board on the SCR module in your drive. What This Kit Contains This kit contains a snubber board assembly and these instructions. SCR module testing and replacement information is included in these instructions. How to Use These Instructions To install a snubber board on your drive: 1. Determine the rating of the drive, refer to “Ratings R060 – R125 and W075 – W125” on page I-6 or “Ratings R150 – R250 and W150 – W250” on page I-28. 2. Access the SCR module, refer to “SCR Module Access” on page I-11 or I-33, depending on the drive rating. 3. Install the snubber board, refer to “Snubber Board Installation” on page I-22 or I-52, depending on the drive rating. If your drive is not working correctly, refer to “SCR Module Test” on page I-24 or I-54, depending on the drive rating. Safety Precautions ! ! ATTENTION: Some printed circuit boards and drive components may contain hazardous voltage levels. Remove and lock out power before you disconnect or reconnect wires, and before you remove or replace fuses and circuit boards. Verify bus voltage by measuring the voltage between +DC and -DC on Terminal Block TB1. Do not attempt to service the drive until the bus voltage has discharged to zero volts. ATTENTION: Potentially fatal voltages may result from improper usage of oscilloscope and other test equipment. The oscilloscope chassis may be at a potentially fatal voltage if not properly grounded. If an oscilloscope is used to measure high voltage waveforms, use only a dual channel oscilloscope in the differential mode with X 100 probes. It is recommended that the oscilloscope be used in the A minus B Quasi-differential mode with the oscilloscope chassis correctly grounded to an earth ground. 1336-5.39 – August, 1999 I-4 Electrostatic Discharge Precautions ! ATTENTION: This assembly contains parts and subassemblies that are sensitive to electrostatic discharge. Static control precautions are required when servicing this assembly. Component damage may result if you ignore electrostatic discharge control procedures. If you are not familiar with static control procedures, reference Allen-Bradley Publication 8000-4.5.2, Guarding Against Electrostatic Damage, or any other applicable ESD protection handbook. Electrostatic discharge generated by static electricity can damage the complimentary metallic oxide semiconductor devices on various drive boards. It is recommended that you perform these procedures to guard against this type of damage when circuit boards are removed or installed: Torque Sequence • Wear a wrist-type grounding strap that is grounded to the drive chassis. • Attach the wrist strap before removing the new circuit board from the conductive packet. • Remove boards from the drive and immediately insert them into their conductive packets. When mounting components to a drive’s heat sink, component-fastener torque sequences and tolerances are crucial to component-to-heat sink heat dissipation. ! ATTENTION: Component can be damaged if temporary tightening procedure is not performed to specification. The following illustrates temporary and final tightening sequences for components fastened to a heat sink using two, four, and six screws. Temporary torque is 1/4 (25%) of final torque. The numeric illustration labels are for your assistance. Drive components do not carry these labels. 1336-5.39 – August, 1999 I-5 Figure I-1 Two-Point Mounting 1 2 Two-Point Mounting 1 2 Temporary Tighten 2 1 AB0906 Final Tighten Figure I-2 Four-Point Mounting 1 3 4 2 Four-Point Mounting 1 2 3 4 2 1 Temporary Tighten 4 3 AB0903 Final Tighten Figure I-3 Six-Point Mounting 4 5 6 2 5 3 6 1 4 Temporary Tighten to 0.5 N-m (4 lb-in.) 3 2 1 2 5 3 6 1 4 Final Tighten to 3 N-m (26 lb-in.)

Frequently asked questions
A snubber board helps to protect your drive's SCR module from damaging voltage spikes. It's often used in applications with high-voltage or rapid switching conditions.
The instruction manual provides a guide to determine if a snubber board is needed for your specific drive model and rating. You can find the information under "Where This Kit is Used" on page I-3.
Always disconnect and lock out power from the drive before disassembling it. Verify there are zero volts at the designated terminals and wear a wrist-type grounding strap to protect the drive components from electrostatic damage.
