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.

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 protection relay.
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 protection relay
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 protection
relay 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.

3 Unpacking, inspecting and storing
3.1 Removing transport packaging
Protection relays 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 protection relay) on the top side of
the unit for the installation phase.
Before connecting the auxiliary power, remove the protective film
from top of the protection relay.
The cardboard packaging material is 100% recyclable.

Installation Manual

3.2 Inspecting product and delivery items
3.2.1 Identifying product
1. Locate the protection relay's order number from the label on top of the plug-in
unit.
2. Compare the protection relay'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
Protection relays require careful handling before installation on site.
• Check the protection relay to see if any damage occurred during transportation.
If the protection relay 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 protection relay 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.

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 protection relay to
allow access to wires and optical fibers to provide sufficient ventilation to the
protection relay and to enable maintenance and future modifications.
• Ensure that flush-mounted protection relays 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.
Mounting 1MRS757641 G
18 620 series
Installation Manual

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 protection relay 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 protection relay 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.
Before fitting the plug-in unit into the case, check that the unit and the
case have the same serial number.

Forcing an unsuitable plug-in unit into the case can break both the plug-
in unit and the case and may cause danger.
