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.
