WARNING!
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 settings have to meet all requirements of the protection
concept (of the equipment that is to be protected). The user must ensure that the device
will properly recognize and manage (e. g.: switch off the Breaker) on the basis of user
selected programming and settings all operational conditions (failures). Before starting
any operation and after any modification of the programming/settings, make a
documented proof that the programming and settings meet the requirements of the
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 example:
• Feeder protection;
• Mains protection;
• Busbar protection;
• Generator protection;
• Transformer protection and
• Machine protection.
This device is not designed for any usage beyond these applications. 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 if this device is used for any application
for which it was not designed. As to the appropriate use of the device: the technical data
specified by Eaton has to be met.
