For technical support on drives betweenthe hours of 7:00 am and 6:00 pm CST, M-F, call 1-262-512-8176. For information about after-hours phone support and on-site support call 1-800-800-0522.Before calling, have the following information availablefrom the Allen-Bradley data nameplate located inside the en-closure on the right wall.

After disconnecting inputpower, wait five (5) minutes for the DC bus capacitors todischarge and then check the voltage with a voltmeter ratedfor the DC bus voltage to ensure the DC bus capacitors aredischarged before touching any internal components. Fail-ure to observe this precaution could result in severe bodilyinjury or loss of life.An isolated multimeter will be needed to measure DC busvoltage and to make resistance checks. The drive’s DC buscapacitors retain hazardous voltages after input power hasbeen disconnected.Fig. 1 — Allen Bradley Data NameplateA19-1830711
