Comments on the Manual
Comments on the Manual
This manual explains in general the tasks of device planning, parameter setting, installation, commissioning,
operation and maintenance of the HighPROTEC devices.
The manual serves as working basis for:
Engineers in the protection field,
commissioning engineers,
people dealing with setting, testing and maintenance of protection and control devices,
as well as trained personnel for electrical installations and power stations.
All functions concerning the type code will be defined. Should there be a description of any functions, parameters or
inputs/outputs which do not apply to the device in use, please ignore that information.
All details and references are explained to the best of our knowledge and are based on our experience and
observations.
This manual describes the (optionally) full featured versions of the devices.
All technical information and data included in this manual reflect their state at the time this document was issued.
We reserve the right to carry out technical modifications in line with further development without changing this
manual and without previous notice. Hence no claim can be brought based on the information and descriptions this
manual includes.
Text, graphic and formulae do not always apply to the actual delivery scope. The drawings and graphics are not
true to scale. We do not accept any liability for damage and operational failures caused by operating errors or
disregarding the directions of this manual.
No part of this manual is allowed to be reproduced or passed on to others in any form, unless Woodward Kempen
GmbH have approved in writing.
This user manual is part of the delivery scope when purchasing the device. In case the device is passed on (sold) to
a third party, the manual has to be handed over as well.
Any repair work carried out on the device requires skilled and competent personnel who need to be well aware
especially of the local safety regulations and have the necessary experience for working on electronic protection
devices and power installations (provided by evidence).
Information Concerning Liability and Warranty
Woodward does not accept any liability for damage resulting from conversions or changes carried out on the
device or planning (projecting) work, parameter setting or adjustment changes done by the customer.
The warranty expires after a device has been opened by others than Woodward specialists.
Warranty and liability conditions stated in Woodward General Terms and Conditions are not supplemented by the
above mentioned explanations.

IMPORTANT DEFINITIONS
IMPORTANT DEFINITIONS
The signal definitions shown below serve the safety of life and limb as well as for the appropriate operating life of
the device.
DANGER indicates a hazardous situation which, if not avoided, will result in
death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION, used with the safety alert symbol, indicates a hazardous
situation which, if not avoided, could result in minor or moderate injury.
NOTICE is used to address practices not related to personal injury.
CAUTION, without the safety alert symbol, is used to address practices not
related to personal injury.

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 has to be wired with the master
communication system (SCADA) in order to supervise and monitor the
state of health of the programmable protective device.
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 (PCB) from the control cabinet
unless absolutely necessary. If you must remove the PCB 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 PCB except the edges.
Do not touch the electrical conductors, the connectors, or the
components with conductive devices or with your hands.
When replacing a PCB, keep the new PCB in the plastic antistatic
protective bag it comes in until you are ready to install it.
Immediately after removing the old PCB 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 82 15,
Guide for Handling and Protection of Electronic Controls, Printed Circuit
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.
