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

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.

Section 2 Environmental aspects
2.1 Sustainable development
Sustainability has been taken into account from the beginning of the product design
including the pro-environmental manufacturing process, long life time, operation
reliability and disposing of the merging unit.
The choice of materials and the suppliers have been made according to the EU RoHS
directive (2002/95/EC). This directive limits the use of hazardous substances which
are the following:
Table 1: Maximum concentration values by weight per homogeneous material
Substance Proposed maximum concentration
Lead - Pb 0.1%
Mercury - Hg 0.1%
Cadmium - Cd 0.01%
Hexavalent Chromium Cr (VI) 0.1%
Polybrominated biphenyls - PBB 0.1%
Polybrominated diphenyl ethers - PBDE 0.1%
Operational reliability and long life time have been assured with extensive testing
during the design and manufacturing processes. Moreover, long life time is supported
by maintenance and repair services as well as by the availability of spare parts.
Design and manufacturing have been done under a certified environmental system.
The effectiveness of the environmental system is constantly evaluated by an external
auditing body. We follow environmental rules and regulations systematically to
evaluate their effect on our products and processes.
2.2 Disposal of a merging unit
Definitions and regulations of hazardous materials are country-specific and change
when the knowledge of materials increases. The materials used in this product are
typical for electric and electronic devices.
All parts used in this product are recyclable. When disposing of a merging unit or its
parts, contact a local waste handler who is authorized and specialized in disposing of
electronic waste. These handlers can sort the material by using dedicated sorting
processes and dispose of the product according to the local requirements.

Section 3 Unpacking, inspecting and storing
3.1 Removing transport packaging
Merging units require careful handling.
1. Examine the delivered products to ensure that they have not been damaged
during the transport.
2. Remove the transport packaging carefully without force.
3. Attach the protective film (supplied with the merging unit) on the top side of the
unit for the installation phase.
Before connecting the auxiliary power, remove the protective
film from top of the merging unit.
The cardboard packaging material is 100% recyclable.
3.2 Inspecting product and delivery items
3.2.1 Identifying product
1. Locate the merging unit's order number from the label on top of the plug-in unit.
2. Compare the merging unit's order number with the ordering information to
verify that the received product is correct.
3.2.2 Checking delivery items
Check that all items are included in the delivery in accordance with the delivery
documents.
3.2.3 Inspecting product
Merging units require careful handling before installation on site.
• Check the merging unit to see if any damage occurred during transportation.

Unpacking, inspecting and storing
SMU615 9
Installation Manual

If the merging unit has been damaged during transportation, make a claim against the
transport contractor, and notify the local ABB representative.
3.2.4 Returning a product damaged in transit
If damage has occurred during transport, appropriate actions must be taken against the
latest carrier. Please inform the nearest ABB office or representative. Notify ABB
immediately if there are any discrepancies in relation to the delivery documents.
3.3 Storing
If the merging unit is stored before installation, it must be done in the original transport
packaging in a dry and dust free place.
Observe the environmental requirements stated in the technical manual.

Section 4 Mounting
4.1 Checking environmental conditions and mounting
space
The mechanical and electrical environmental conditions at the installation site must be
within the limits described in the technical manual.
• Avoid installation in dusty, damp places.
Avoid places susceptible to rapid temperature variations, powerful vibrations and
shocks, surge voltages of high amplitude and fast rise time, strong induced
magnetic fields or similar extreme conditions.
• Check that sufficient space is available.
Sufficient space is needed at the front and rear of the merging unit to allow access
to wires and optical fibers to provide sufficient ventilation to the merging unit and
to enable maintenance and future modifications.
• Ensure that flush-mounted merging units can be added and replaced without
excessive dismantling.
4.2 Detaching and installing plug-in unit
4.2.1 Detaching plug-in unit
Before detaching the plug-in unit from the case, the auxiliary voltage
must be disconnected.
1. Turn off the power.
2. Open the seal on the front panel by removing the sealing wire and screw the
sealing screw all the way in.
3. Lift the handle to 90 degrees to release the latching mechanism.
The plug-in unit is pushed about 7 mm out of the case and the connectors are
separated.
4. Pull the unit out of the case.

Figure 2: Detaching a plug-in unit from the case
The merging unit features an automatic short-circuit mechanism in the
CT connector. Therefore, detaching the plug-in unit will not open the
secondary circuit of the CT which could cause dangerously high
voltages.
Do not touch terminals inside the case after removing the plug-in unit.
Live terminals can be inside the case.
The signal connectors are left open when the plug-in unit is detached.
4.2.2 Installing plug-in unit
The merging unit is constructed in a way that a plug-in unit with voltage- or current-
measuring inputs can only be plugged into a corresponding case. This prevents fitting
an unsuitable plug-in unit into a wrong case.
