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.
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. 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.
