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.

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 ABB 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.
