Disclaimer
The data, examples and diagrams in this manual are included solely for the concept
or product description and are not to be deemed as a statement of guaranteed
properties. All persons responsible for applying the equipment addressed in this
manual must satisfy themselves that each intended application is suitable and
acceptable, including that any applicable safety or other operational requirements
are complied with. In particular, any risks in applications where a system failure
and/or product failure would create a risk for harm to property or persons
(including but not limited to personal injuries or death) shall be the sole
responsibility of the person or entity applying the equipment, and those so
responsible are hereby requested to ensure that all measures are taken to exclude or
mitigate such risks.
This product has been designed to be connected and communicate data and
information via a network interface which should be connected to a secure
network. It is the sole responsibility of the person or entity responsible for network
administration to ensure a secure connection to the network and to take the
necessary measures (such as, but not limited to, installation of firewalls, application
of authentication measures, encryption of data, installation of anti virus programs,
etc.) to protect the product and the network, its system and interface included,
against any kind of security breaches, unauthorized access, interference, intrusion,
leakage and/or theft of data or information. ABB is not liable for any such damages
and/or losses.
This document has been carefully checked by ABB but deviations cannot be
completely ruled out. In case any errors are detected, the reader is kindly requested
to notify the manufacturer. Other than under explicit contractual commitments, in
no event shall ABB be responsible or liable for any loss or damage resulting from
the use of this manual or the application of the equipment. In case of discrepancies

version shall prevail.

Conformity
This product complies with the directive of the Council of the European
Communities on the approximation of the laws of the Member States relating to
electromagnetic compatibility (EMC Directive 2014/30/EU) and concerning
electrical equipment for use within specified voltage limits (Low-voltage directive
2014/35/EU). This conformity is the result of tests conducted by the third party
testing laboratory KEMA in accordance with the product standard EN 60255-26
for the EMC directive, and with the product standards EN 60255-1 and EN
60255-27 for the low voltage directive. The product is designed in accordance with
the international standards of the IEC 60255 series.

Safety information
Dangerous voltages can occur on the connectors, even though the
auxiliary voltage has been disconnected.
Non-observance can result in death, personal injury or substantial
property damage.
Only a competent electrician is allowed to carry out the electrical
installation.
National and local electrical safety regulations must always be
followed.
The frame of the protection relay has to be carefully earthed.
When the plug-in unit has been detached from the case, do not
touch the inside of the case. The relay case internals may contain
high voltage potential and touching these may cause personal
injury.
The protection relay contains components which are sensitive to
electrostatic discharge. Unnecessary touching of electronic
components must therefore be avoided.
Whenever changes are made in the protection relay, measures
should be taken to avoid inadvertent tripping.
