WX9 ASD 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).
•
Power factor improvement capacitors or surge absorbers
MUST NOT
be installed on the three-
phase output of the ASD.
•
Use of the built-in system protective features is highly recommended (i.e., Emergency 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
.
•
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., Emergency 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
and
Retry
settings is 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
•
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. Warning signs to this effect must be
clearly posted at or near the machinery/hazard.
•
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 three-phase output of
the ASD is active may result in equipment damage or injury to personnel.
Dynamic Braking Precaution
•
The Dynamic Braking function is
NOT
used with the
WX9 ASD
.
•
DO NOT
attempt to configure or connect the DBR function to the
WX9 ASD
.
•
Attempts to configure or adapt the ASD to use the Dynamic Braking function may result in
system damage or injury to personnel.
