Static control precautions are required when installing, testing, servicing or repairing this assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with static control procedures, reference A-B publication , Guarding Against Electrostatic Damage or any other applicable ESD protection guide. ATTENTION: Only qualified personnel familiar with adjustable frequency AC drives and associated machinery should perform maintenance/repair of the system. Failure to comply may result in personal injury and/or equipment damage. ATTENTION: The following information is merely a guide for proper installation. Rockwell Automation cannot assume responsibility for the compliance or the noncompliance to any code, national, local or otherwise for the proper installation of this drive or associated equipment.

3 Step: 1 Remove Power from the Drive ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before performing any work on the drive. Measure the DC bus voltage at the DC+ & DC- terminals. The voltage must be zero. ATTENTION: Remove power before making or breaking cable connections. When you remove or insert a cable connector with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by: sending an erroneous signal to your system s field devices, causing unintended machine motion causing an explosion in a hazardous environment Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance. 1. Turn off and lock out input power. Wait five minutes. 2. Verify that there is no voltage at the drive s input power terminals. 3. Measure the DC bus voltage at the DC+ & DC- terminals on the power terminal block. The voltage must be zero.

Tightening torque for re-assembly is 3 N m (27 lb in.). L1 L2 L3 L1 L2 L3 U/T1 V/T2 W/T3 U/T1 V/T2 W/T3 Rockwell Automation Publication PFLEX-IN024B-EN-P - September

4 S1 X7 X5 X6 X1 X4 Step: 3 Remove the Existing Fan Capacitor 1. If necessary, remove the cables from the input power terminals (L1, L2 and L3). 2. Remove the M4 x 8 mm POZIDRIV screw that secures the fan inverter cover to the drive frame and remove the cover. Discard the existing fan inverter cover and screw -- new parts are provided in the kit. = X2X ON 4 Rockwell Automation Publication PFLEX-IN024B-EN-P - September 2011

5 IMPORTANT Mark all connections and wires before removing to avoid incorrect wiring during reassembly. 3. Remove the fuses from the fuse holder. 4. Disconnect the four fuse signal wires (black and red pairs) connected to the top and bottom of the fuse holder. IMPORTANT Note that the red wires connect to the left side terminal on the fuse holder and the black wires connect to the right side terminal on the fuse holder. 5. Disconnect the stirring fan power wires. Red wire Black wire Disconnect fuse signal wires from fuse holder Remove fuses from fuse holder Disconnect fuse signal wires from fuse holder Red wire Black wire Disconnect stirring fan power wires 6. Remove the two M5 x 10 mm POZIDRIV screws that secure the fan capacitor, fuse holder and fan bracket to the drive frame, and lift the bracket out of the drive. Note that the fan capacitor is still connected to the drive circuitry. Discard the two M5 x 10 mm screws -- new hardware is provided in the kit. 7. Disconnect the capacitor wires from the connectors labelled Blue and Brown. Rockwell Automation Publication PFLEX-IN024B-EN-P - September

7 IMPORTANT Note the orientation of the air flow direction arrow on the fan housing before removal. The fan must be installed facing the same direction when re-installed. 8. Remove the two M4 x 16 mm POZIDRIV screws that secure the stirring fan to the bracket and remove the fan. Save the fan for reuse. Discard the two M4 x 16 mm screws -- new hardware is provided in the kit. 9. Remove the two M4 x 8 mm POZIRDRIV screws that secure the fuse holder to the bracket and remove the fuse holder. Save the fuseholder for reuse. Discard the two M4 x 8 mm screws -- new hardware is provided in the kit. 10. Discard the existing fan capacitor and bracket. Remove screws and fuse holder Remove screws and stirring fan. Note direction of air flow arrow. Rockwell Automation Publication PFLEX-IN024B-EN-P - September

8 Step: 4 Install the New Fan Capacitor and Bracket Install the new fan capacitor and bracket in the reverse order of removal. 1. Secure the new fan capacitor to the new bracket using the new M12 lock washer and M12 nut provided in the kit. Tightening torque is 12 N m (106 lb in.). Secure new capacitor to new bracket with lock washer and nut 2. Secure the existing fuse holder to the bracket using the two new M4 x 8 mm POZIDRIV screws provided in the kit. Tightening torque is 2 N m (18 lb in.). 3. Verify that the air flow arrow on the fan points in the same direction as was noted before removal, and secure the existing stirring fan to the bracket using the two new M4 x 16 mm POZIDRIV screws. Tightening torque is 1.5 N m (13 lb in.). Verify that the fan blades turn freely Verify that the power wires are located nearest to the bracket Verify that the air flow arrow on fan points in the correct direction. 4. Install the existing fuses in the fuse holder. 5. Connect the blue fan capacitor wire to the connector labelled Blue and the brown fan capacitor wire to the connector labelled Brown. 8 Rockwell Automation Publication PFLEX-IN024B-EN-P - September 2011

9 6. Connect the upper red and black pair of fuse wires (from X2 on the fan inverter circuit board) to the top of the fuse holder. Verify that the proper color wire is connected to the appropriate terminal on the fuse holder. See step 4 on page Insert the capacitor wires into the chassis so that they do not interfere with the stirring fan blades, insert the bracket with the fan capacitor, fuse holder and stirring fan into the drive chassis and secure the bracket with the two M5 x 10 mm POZIDRIV screws provided in the kit. Tightening torque is 4 N m (35 lb in.). 8. Connect the bottom red and black pair of fuse wires to the bottom of the fuse holder. Verify that the proper color wire is connected to the appropriate terminal on the fuse holder. See step 4 on page Connect the stirring fan power wires to the connector on the stirring fan. 10. Secure the new fan inverter cover to the drive chassis using the new M4 x 8 mm POIDRIV screw provided in the kit. Tightening torque is 2 N m (17 lb in.).
