System Setup Requirements - Toshiba Q9 Installation And Operation Manual

System Setup Requirements

• When using the ASD as an integral part of a larger system, it is the responsibility of the
ASD installer/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
system damage or injury to personnel (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 are a requirement to use this product.
• Improperly designed or improperly installed system interlocks may render the motor unable to start
or stop on command.
• DO NOT install power factor improvement/correction capacitors or surge absorbers 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
• The Dynamic Braking function is NOT used with the Q9 ASD.
• DO NOT attempt to configure or connect the DBR function to the Q9 ASD.
• Attempts to configure or adapt the ASD to use the Dynamic Braking function may result in system
damage or injury to personnel.
• If a secondary magnetic contactor (MC) or an ASD output disconnect 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, or W).
• When using an ASD output disconnect, the ASD and the motor must be stopped before the
disconnect is either opened or closed. Closing the output disconnect while the 3-phase output of the
ASD is active may result in equipment damage or injury to personnel.
