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 asis 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 e defined. Should there e 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 est of our knowledge and are ased on our experience and
o servations.
This manual descri es 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 e rought ased 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 lia ility for damage and operational failures caused y operating errors or
disregarding the directions of this manual.
No part of this manual is allowed to e reproduced or passed on to others in any form, unless Woodward SEG
GmbH & Co. KG 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 e handed over as well.
Any repair work carried out on the device requires skilled and competent personnel who need to e well aware
especially of the local safety regulations and have the necessary experience for working on electronic protection
devices and power installations (provided y evidence).
Information Concerning Liability and Warranty
Woodward SEG does not accept any lia ility for damage resulting from conversions or changes carried out on
the device or planning (projecting) work, parameter setting or adjustment changes done y the customer.
The warranty expires after a device has een opened y others than Woodward SEG specialists.
Warranty and lia ility conditions stated in Woodward SEG’s General Terms and Conditions are not
supplemented y the a ove mentioned explanations.

IMPORTANT DEFINITIONS
IMPORTANT DEFINITIONS
The signal definitions shown elow serve the safety of life and lim 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.
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).
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
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 SEG 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:
•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 82715,
Guide for Handling and Protection of Electronic Controls, Printed Circuit
Boards, and Modules.
Woodward SEG reserves the right to update any portion of this pu lication at any time. Information provided y
Woodward SEG is elieved to e correct and relia le. However, no responsi ility is assumed y Woodward SEG
unless otherwise expressly undertaken.

Device Planning
Planning of a device means to reduce the functional range to a degree that suits the protection task to e
fulfilled, i.e. the device shows only those functions you really need. If you, for example, deactivate the voltage
protection function, all parameter ranches related to this function do not appear in the parameter tree any more.
All corresponding events, signals etc. will e deactivated too. By this the parameter trees ecome very
transparent. Planning also involves adjustment of all asic system data (frequency etc.).
But it has to be taken into account that by deactivating, for instance,
protective functions, you also change the functionality of the device. If you
cancel the directional feature of the overcurrent protections then the device
no longer trips in a directional way but merely in a non directional way.
The manufacturer does not accept liability for any personal or material
damage as a result of wrong planning.
A planning service is also offered by Woodward SEG.
Beware of inadvertent deactivating protective functions/modules
If you are deactivating modules within the device planning all parameters of
those modules will be set on default.
If you are activating one of these modules again all parameters of those
reactivated modules will be set on default.
