8 P9 ASD Installation and Operation Manual
System Setup Requirements
• With the exception of the TBA Pump Number ( F434 ), ensure that all Time-Based Alternation
parameter settings and the real-time clock settings for each ASD within the system are the same.
• 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).
• 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 .
• 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
Time-Based Alternation ( F404 ), ( Virtual Linear Pump)
Auto Start-Stop ( F385 ), Auto-Restart ( F301 ), and the Sleep Timer ( F383 ) settings are a
requirement to use this product.
• The setup procedures included within this manual may require a Reset before performing the
procedure. Application-specific settings may then be performed. The pre-Reset conditions may be
saved (see
F007 ).
• 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 to this effect must be posted
at the equipment installation location.
• 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.
