ATTENTION: Do not install or remove modification kits with power applied to the drive. Disconnect
and lock out incoming power before attempting such installation or removal. Failure to observe this
precaution could result in severe bodily injury or loss of life.
!
ATTENTION: DC Bus capacitors retain hazardous voltages after input power has been disconnected.
After disconnecting input power, wait five (5) minutes for the DC bus capacitors to discharge and then
check the voltage with a voltmeter to ensure that the DC bus capacitors are discharged before touching
any internal components. Failure to observe this precaution could result in severe bodily injury or loss of
life.
!
ATTENTION: The user is responsible for conforming with all applicable local, national, and
international codes. Failure to observe this precaution could result in damage to, or destruction of, the
equipment.
!
ATTENTION: The drive contains ESD- (Electrostatic Discharge) sensitive parts and assemblies. Static
control precautions are required when installing, testing, servicing or repairing the drive. Erratic machine
operation and damage to, or destruction of, equipment can result if this procedure is not followed.
Failure to observe this precaution could result in severe bodily injury or loss of life.
