ATTENTION
!
DC bus capacitors may retain hazardous voltages after
input power has been removed. Before working on the
drive, measure the DC bus voltage to verify it has reached a
safe level or wait the full time interval listed on the drive
warning label. Failure to observe this precaution could
result in severe bodily injury or loss of life.
Do not attempt to defeat or override the drive fault circuits.
You must determine the cause of a fault and correct it
before you attempt to operate the system. If you do not
correct a drive or system malfunction, it could result in
personal injury and/or damage to the equipment as a result
of uncontrolled machine system operation.
Test equipment (such as an oscilloscope or chart recorder)
must be properly grounded. Failure to include an earth
ground connection could result in a potentially fatal voltage
on the oscilloscope chassis.
