•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.,
•The programming setup and system configuration of the ASD may allow it to start the motor unexpectedly. A familiarity with the
•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 to this effect must be posted at the equipment installation site and near the driven equipment.
•If a secondary magnetic contactor (MC) is used between the ASD output 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).
•Power factor improvement capacitors or surge absorbers must not be installed on the output of the ASD.
•Use of the
•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.
