IMPORTANT DEFINITIONS
FOLLOW INSTRUCTIONS
Read this entire manual and all other publications pertaining to the work to be
performed before installing, operating, or servicing this equipment. Practice all
plant and safety instructions and precautions. Failure to follow instructions can
cause personal injury and/or property damage.
PROPER USE
Any unauthorized modifications to or use of this equipment outside its
specified mechanical, electrical, or other operating limits may cause
personal injury and/or property damage, including damage to the
equipment. Any such unauthorized modifications: (1) constitute "misuse"
and/or "negligence" within the meaning of the product warranty thereby
excluding warranty coverage for any resulting damage, and (2) invalidate
product certifications or listings.
The programmable devices subject to this manual are designed for
protection and also control of power installations and operational devices
that are fed by voltage sources with a fixed frequency, i.e. fixed at 50 or 60
Hertz. They are not intended for use with Variable Frequency Drives. The
devices are further designed for installation in low-voltage (LV)
compartments of medium voltage (MV) switchgear panels or in de-
centralized protection panels. The programming and parameterization has
to meet all requirements of the protection concept (of the equipment that is
to be protected). You must ensure that the device will properly recognize
and manage (e.g. switch off the circuit breaker) on the basis of your
programming and parameterization all operational conditions (failures). The
proper use requires a backup protection by an additional protective device.
Before starting any operation and after any modification of the
programming (parameterization) test make a documentary proof that your
programming and parameterization meets the requirements of your
protection concept.
The Self-Supervision Contact (Life-Contact) has to be wired with the
substation automation system in order to supervise and monitor the state
of health of the programmable protective device. It is very important that an
alarm annunciation is driven from the programmable protective device self-
supervision contact (Life-Contact) that requires immediate attention when
tripped. The alarm indicates that the protective device is no longer
protecting the circuit and the system should be serviced.
Typical applications for this product family/device line are for instance:
Feeder protection
Mains protection
Machine protection
Transformer Differential Protection
Any usage beyond these applications the devices are not designed for. This
applies also to the use as a partly completed machinery. The manufacturer
cannot be held liable for any resulting damage, the user alone bears the
risk for this. As to the appropriate use of the device: The technical data and
tolerances specified by Woodward have to be met.
