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 merging unit 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 merging unit case internals may contain
high voltage potential and touching these may cause personal injury.
The merging unit contains components which are sensitive to electrostatic
discharge. Unnecessary touching of electronic components must therefore be
avoided.
Whenever changes are made in the merging unit, measures should be
taken to avoid inadvertent tripping.
