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.
