Qualified Personnel
ATTENTION: Only qualified personnel familiar with adjustable frequency AC
drives and associated machinery can plan or implement the installation,
startup, and subsequent maintenance of the system. Failure to comply can
result in personal injury and/or equipment damage.
Personal Safety
ATTENTION: To avoid an electric shock hazard, verify that the voltage on the
bus capacitors has discharged before performing any work on the drive.
Measure the DC bus voltage at the +DC terminal of the Power Terminal Block
and the -DC test point (refer to
must be zero.
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 exist, an additional hardwired stop
circuit may be required to remove the AC line to the drive. An auxiliary braking
method may be required.
Product Safety
ATTENTION: An incorrectly applied or installed drive can result in component
damage or a reduction in product life. Wiring or application errors, such as,
undersizing the motor, incorrect or inadequate AC supply, or excessive ambient
temperatures can result in malfunction of the system.
ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive parts
and assemblies. Static control precautions are required when installing, testing,
servicing or repairing this assembly. Component damage can result if ESD
control procedures are not followed. If you are not familiar with static control
procedures, reference Guarding Against Electrostatic Damage, publication
8000-4.5.2 or any other applicable ESD protection handbook.
ATTENTION: Configuring an analog input for 0...20 mA operation and driving
it from a voltage source could cause component damage. Verify proper
configuration before applying input signals.
ATTENTION: A contactor or other device that routinely disconnects and
reapplies the AC line to the drive to start and stop the motor can cause drive
hardware damage. The drive is designed to use control input signals that start
and stop the motor. If an input device is used, operation must not exceed 1 cycle
per minute or drive damage can occur.
