ATTENTION: This product contains stored energy
devices. To avoid hazard of electrical shock, verify that
!
all voltage on the capacitors has been discharged before
attempting to service, repair, or remove this unit. You
should only attempt the procedures in this chapter if
you are qualified to do so and familiar with solid-state
control equipment and the safety procedures in
publication NFPA 70E.
ATTENTION: 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 equipment as a result of uncontrolled
machine system operation.
ATTENTION: If you use an oscilloscope (or chart
recorder) for troubleshooting, you must properly
ground it. The oscilloscope chassis can be at a
potentially fatal voltage if you do not properly ground
it. Always connect the oscilloscope chassis to an earth
ground.
