1.1 About the complete set of manuals to a terminal
The complete package of manuals to a terminal is named users manual (UM). The Us-
ers manual consists of four different manuals:
The Application Manual (AM) contains descriptions, such as application and func-
tionality descriptions as well as setting calculation examples sorted per function. The
application manual should be used when designing and engineering the protection ter-
minal to find out where and for what a typical protection function could be used. The
manual should also be used when calculating settings and creating configurations.
The Technical Reference Manual (TRM) contains technical descriptions, such as
function blocks, logic diagrams, input and output signals, setting parameter tables and
technical data sorted per function. The technical reference manual should be used as a
technical reference during the engineering phase, installation and commissioning phase
and during the normal service phase.
The Operator´s Manual (OM) contains instructions on how to operate the protection
terminal during normal service (after commissioning and before periodic maintenance
tests). The operator´s manual could be used to find out how to handle disturbances or
how to view calculated and measured network data in order to determine the reason of
a fault.
The Installation and Commissioning Manual (ICM) contains instructions on how to
install and commission the protection terminal. The manual can also be used as a refer-
ence if a periodic test is performed. The manual covers procedures for mechanical and
electrical installation, energising and checking of external circuitry, setting and config-
uration as well as verifying settings and performing a directionality test. The chapters
and sections are organised in the chronological order (indicated by chapter/section
numbers) the protection terminal should be installed and commissioned.

• The chapter “Establishing connection and verifying the SPA/IEC-communication”
contains instructions on how to enter SPA/IEC settings and verifying the SPA/IEC
communication.
•Thechapter“Verifying settings by secondary injection” contains instructions on
how to verify that each included function operates correctly according to the set val-
ue.
•Thechapter“Verifying the internal configuration” contains instructions on how
verify that the terminal is properly configured.

Chapter 2 Safety information
About this chapter
This chapter contains safety information. Warning signs are presented which attend the
user to be careful during certain operations in order to avoid human injuries or damage
to equipment

Warning signs Chapter 2
Safety information
1 Warning signs
Warning!
Strictly follow the company and country safety regulations. Working in a high voltage
environment requires serious approach to avoid human injuries and damage to equip-
ment.
Warning!
Do not touch circuitry during operation. Potentially lethal voltages and currents are
present.
Warning!
Always avoid to touch the circuitry when the cover is removed. The product contains
electronic circuitries which can be damaged if exposed to static electricity (ESD). The
electronic circuitries also contain high voltage which is lethal to humans.
Warning!
Always use suitable isolated test pins when measuring signals in open circuitry. Poten-
tially lethal voltages and currents are present.
Warning!
Never connect or disconnect a wire and/or a connector to or from a terminal during
normal operation. Hazardous voltages and currents are present that may be lethal. Op-
eration may be disrupted and terminal and measuring circuitry may be damaged.
Warning!
Always connect the terminal to protective ground, regardless of the operating condi-
tions. This also applies to special occasions such as bench testing, demonstrations and
off-site configuration. Operating the terminal without proper grounding may damage
both terminal and measuring circuitry, and may cause injuries in case of an accident.

7
Warning signs Chapter 2
Safety information
Warning!
Never disconnect a secondary connection of current transformer circuit without short-
circuiting the transformer’s secondary winding. Operating a current transformer with
the secondary winding open will cause a massive potential build-up that may damage
the transformer and may cause injuries to humans.
Warning!
Never unmount the front or back cover from a powered terminal or from a terminal con-
nected to powered circuitry. Potentially lethal voltages and currents are present.

8
Caution signs Chapter 2
Safety information
2 Caution signs
Caution!
Always transport modules using certified conductive bags. Always handle modules us-
ing a conductive wrist strap connected to protective ground and on a suitable antistatic
surface. Electrostatic discharge (ESD) may cause damage to the module.
Caution!
Do not connect live wires to the terminal. Internal circuitry may be damaged
Caution!
Always use a conductive wrist strap connected to protective ground when replacing
modules. Electrostatic discharge (ESD) may damage the module and terminal circuit-
ry.
Caution!
Take care to avoid electrical shock if accessing wiring and connection terminals when
installing and commissioning.

9
Note signs Chapter 2
Safety information
3 Note signs
Note!
Changing the active setting group will inevitably change the terminal’s operation. Be
careful and check regulations before making the change.
Note!
The protection assembly is designed for a maximum continuous current of four times
rated value.
Note!
Activating the setting lockout function, which prevents unauthorised changes of the set-
tings, without proper configuration may seriously affect the terminal’s operation.

Overview
1 Commissioning and installation overview
The settings for each function must be calculated before the commissioning task can
start. A configuration, made in the configuration and programming tool, must also be
available if the terminal does not have a factory configuration downloaded.
The terminal is unpacked and visually checked. It is preferably mounted in a cubicle or
on a wall. The connection to the protection system has to be checked in order to verify
that the installation was successful.
The installation and commissioning task starts with configuring thedigital communica-
tion modules, if included. The terminal can then be configured and set, which means
that settingsand a configuration has to be appliedif the terminal does not have a factory
configuration downloaded. Then the operation of each included function according to
applied settings has to be verified by secondary injection. A complete check of the con-
figuration can then be made. A conformity test of the secondary system has also to be
done. When the primary system has been energised a directionality check should be
made.

Unpacking and checking the
terminal
1 Receiving, unpacking and checking
Procedure
1. Remove the transport casing.
2. Visually inspect the terminal.
3. Check that all items are included in accordance with the de-
livery documents.
The user is requested to check that all software functions are in-
cluded according to the delivery documents after the terminal has
been energised.
4. Check for transport damages.
In case of transport damage appropriate action must be taken
against the latest carrier and the nearest ABB office or representa-
tive should be informed. ABB should be notified immediately if
there are any discrepancies in relation to the delivery documents.
Store the terminal in the original transport casing in a dry and dust
free place, if the terminal is not to be installed or commissioned
immediately. Observe the environmental requirements stated in
the technical data.
