Qualified Personnel
ATTENTION: Only qualified personnel familiar with adjustable frequency AC
drives and associated machinery should plan or implement the installation,
start-up and subsequent maintenance of the system. Failure to comply may
result in personal injury and/or equipment damage.
Personal Safety
ATTENTION: To avoid an electric shock hazard, ensure that all power to the
drive has been removed before proceeding. In addition, before servicing, verify
that the voltage on the bus capacitors has discharged. Measure the DC bus
voltage on Frame 8 drives at the DC+ and DC- TESTPOINT sockets on the front of
the power module (see
ATTENTION: Hazard of personal injury or equipment damage exists when
using bipolar input sources. Noise and drift in sensitive input circuits can cause
unpredictable changes in motor speed and direction. Use speed command
parameters to help reduce input source sensitivity.
ATTENTION: Risk of injury or equipment damage exists. DPI™ or SCANport™
host products must not be directly connected together via 1202 cables.
Unpredictable behavior can result if two or more devices are connected in this
manner.
ATTENTION: The drive start/stop/enable control circuitry includes solid state
components. If hazards due to accidental contact with moving machinery or
unintentional flow of liquid, gas or solids exists, an additional hardwired stop
circuit may be required to remove the AC line to the drive. An auxiliary braking
method may be required.
