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 ontact (Life- ontact) 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- ontact) 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.

IMPORTANT DEFINITIONS
Electrostatic Discharge Awareness
All electronic equipment is electro static-sensitive, some components more
than others. To protect these components from electro static damage, you
must take special precautions to minimize or eliminate electrostatic
discharges.Follow these precautions when working with or near the
control.
1. Before doing maintenance on the electronic control, discharge the
static electricity on your body to ground by touching and holding a
grounded metal object (pipes, cabinets, equipment, etc.).
2. Avoid the build-up of static electricity on your body by not wearing
clothing made of synthetic materials. Wear cotton or cotton-blend
materials as much as possible because these do not store static
electric charges as much as synthetics.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or
Styrofoam cups, cup holders, cigarette packages, cellophane
wrappers, vinyl books or folders, plastic bottles, and plastic ash trays)
away from the control, the modules, and the work area as much as
possible.
4. Do not remove any printed circuit board (P B) from the control cabinet
unless absolutely necessary. If you must remove the P B from the
control cabinet, follow these precautions:
Verify the safe isolation from supply. All connectors have to be
unplugged.
Do not touch any part of the P B except the edges.
Do not touch the electrical conductors, the connectors, or the
components with conductive devices or with your hands.
When replacing a P B, keep the new P B in the plastic antistatic
protective bag it comes in until you are ready to install it.
Immediately after removing the old P B from the control cabinet,
place it in the antistatic protective bag.
To prevent damage to electronic components caused by improper
handling, read and observe the precautions in Woodward manual 82715,
Guide for Handling and Protection of Electronic ontrols, Printed ircuit
Boards, and Modules.
Woodward reserves the right to update any portion of this publication at any time. Information provided by
Woodward is believed to be correct and reliable. However, no responsibility is assumed by Woodward unless
otherwise expressly undertaken.
