Publication 1336 IMPACT-6.2 – March 1998
7. If the voltage is out of tolerance, check the following:
• An open condition at Input Rectifier SCR1
• A voltage drop due to Bus Inductor L1 resistance
• A voltage drop between Input Rectifier SCR1 and the bus
capacitors due to loose or resistive wires or connections
• Precharge circuit problems
8. If the above check does not reveal a problem, replace the Bus
Capacitor Bank and Load-Sharing Resistors. Refer to
Chapter 5 – Part Replacement Procedures, Bus Capacitor Bank.

ATTENTION: Replace all guards and insulators
before applying power to the drive. Failure to replace
guards may result in death or serious injury.
