System Setup Requirements
WARNING
• The parameter settings affect how the drive operates. Only Qualified
Personnel should set or change parameters.
• When using the ASD as an integral part of a larger system, it is the
responsibility of the ASD installer or maintenance personnel to ensure that
there is a fail-safe in place, i.e., an arrangement designed to switch the
system to a safe condition if there is a fault or failure.
• System safety features should be employed and designed into the
integrated system in a manner such that system operation, even in the
event of system failure, will not cause harm or result in personnel injury or
system damage (i.e., E-Off, Auto-Restart settings, System Interlocks, etc.).
• The programming setup and system configuration of the ASD may allow it
to start the motor unexpectedly. A familiarity with the Auto-restart settings
is a requirement to use this product.
• Improperly designed or improperly installed system interlocks may render
the motor unable to start or stop on command.
• The failure of external or ancillary components may cause intermittent
system operation, i.e.; the system may start the motor without warning.
• There may be thermal or physical properties, or ancillary devices
integrated into the overall system that may allow for the ASD to start the
motor without warning. Signs at the equipment installation must be posted
to this effect.
• If a secondary magnetic contactor (MC) is used between the ASD and the
load, it should be interlocked to halt the ASD before the secondary contact
opens. If the output contactor is used for bypass operation, it must be
interlocked such that commercial power is never applied to the ASD output
terminals (U, V, and W).
• Power factor improvement capacitors or surge absorbers must not be
installed on the output of the ASD.
• Use of the built-in system protective features is highly recommended (i.e.,
E-Off, Overload Protection, etc.).
• The operating controls and system status indicators should be clearly
readable and positioned where the operator can see them without
obstruction.
• Additional warnings and notifications shall be posted at the equipment
installation location as deemed required by Qualified Personnel.
