8 ACE-tronics G9 ASD Installation and Operation Manual
System Setup Requirements
• When using the ACE-tronics G9 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
t
hat 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
une
xpectedly. A familiarity with the Auto-Restart settings are a requirement to use this product.
• Power factor improvement/correction capacitors or surge absorbers MUST
NOT be installed on the
output of the ACE-tronics G9 ASD.
• Use of the built-in system protective features is highly recommended (i.e., E-Off, Overload
P
rotection, 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
de
emed required by Qualified Personnel.
• There may be thermal or physical properties, or ancillary devices integrated into the overall system
that may allow for the ACE-tronics G9 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, 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.
