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 may 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: Only qualified personnel familiar with adjustable frequency
AC drives and associated machinery should perform maintenance/repair of
the system. Failure to comply may result in personal injury and/or
equipment damage.
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 & –DC terminals of the
Power Terminal Block (refer to the User Manual for location). The voltage
must be zero.
