Combi arrester against lightning and surges for photovoltaic systems
The photovoltaic system also requires
safety measures: Effective
protection against lightning strikes
and electrical surges is extremely
necessary in order that the facil-
ity doesn’t experience any nasty
surprises even before the amortisation
period has ended. Added
to that, regional building regulations
as well as property insurers
under the VdS directive for certain
buildings and plants require that
lightning and electrical surge protection
is in place.

protection, a direct lightning strike
into the PV module must be prevented
by the lightning protection system.

Be on the safe side
Lightning and surge protection
for photovoltaic systems
The outward signs of a photovoltaic system are the solar modules. With its comprehensive range, OBO
ensures the integration of the system into the entire building installation. With our transient and lightning
protection products, we offer everything that you need for a clean installation.
Combi arrester for main power
supply
Through the combined lightning current
and surge arrester (class 1+2) a
lightning current equipotential bonding
according to EN 62305 as well
as surge protection according to IEC
60364-5-53 can be conducted.
Lightning current arresters must
be integrated into the equipotential
bonding in a way which makes
them capable of withstanding
lightning current (min.
16 mm 2 copper).

Photovoltaic generator laminated on a metal roof
Suitable solutions
Modular and installation-ready solutions for DC and AC systems:
Lightning and surge protection safeguards property and increases availability.
Protected photovoltaic
generator
If the photovoltaic module lies within
the protection range of the lightning
interceptor, and if the distance to the
lightning protection system is maintained,
then instead of the combination
arrester, a type 2 surge protection
device may also be used.
If the distance between the photovoltaic
plant and the lightning protection
system cannot be maintained
(e.g. with a metal roof), the systems
should be connected with at least
16 mm 2 (copper).
At the building entry (LPZ 0-1) possible
partial lightning currents should
be dealt with by the appropriate combi
arrester (type 1 or types 1+2). OBO
offers suitable combination lightning
arrestors for DC applications.

The perfect choice
KTS systems for photovoltaic systems
Around the world, the OBO brand stands for certified quality and for innovative products developed and
manufactured in-house. No matter whether you are laying power cables, outfitting industrial buildings
with complete cable support systems or installing photovoltaic systems – with OBO products, you’re
always in safe hands.
OBO offers you all possibilities
A comprehensive range of practical,
more efficient and easier-to-mount
cable support systems as the perfect
solution to any installation task.
We offer you a broad spectrum of
materials and surfaces for operational
areas, both indoors and out, as well as
a high mechanical robustness against
chemical influences by means of our
epoxy-polyester coating.

For many years, customers from industry and from the plant construction
and building engineering sectors have trusted the experience and know-how
of the globally active OBO Bettermann group.
For universal application, OBO provides
tailor-made cable support systems
in its range. From low voltage
current transferral through to energy
supply. Available in diverse heights,
widths and in varying surface and
material quality.
OBO offers a variety of covers for all
systems, to provide additional protection
for pipes from the effects of
weather and mechanical demands.
11

A long-lasting choice
Fire protection solutions for photovoltaic systems
There is a high level of requirement attached to the fire safety of installations in modern buildings. OBO offers
a complete product range for fire safety-conscious electronic installation. Be it sealing systems, fire protection
ducts or installation systems for security-relevant plants – this entire one-stop package fulfils all prevention
goals as required by building regulations: to hinder the spreading of fire, to secure emergency routes and to
maintain function. In this way, it is not only the photovoltaic system that is protected, but also the entire
building.
12

Fire protection seminars
OBO offers an abundance of seminars
for electronic installation engineers,
planners and architects. The complex
areas of fire protection and surge protection
especially invite clarification
and number among the classic seminar
subjects.
Visit the OBO seminars and let yourself
be brought right up to date.
Safe cable routing
When cables penetrate the fire protection walls of photovoltaic systems, or
when they need to be installed in escape routes, then special measures are
required. These apply especially in public buildings. OBO offers here a comprehensive
range from cable compartmentalisation through to escape route
installation.

A clean choice
Installation solutions
for photovoltaic systems
Alongside the aspect of protection against lightning and electricity surges, the installation engineer finds themself
faced with the task of installing the pipeline facility in accordance with architectural and static conditions.
It is also here that the emphasis falls on the protection of the cables and pipes against damage, as well as the
protection of the entire facility against moisture damage. OBO Bettermann is at your side with its fastening and
fitting systems which have been established in the market for years.
Diversity is the key
Because of the number of different
installation conditions,
there are also constantly new
demands made on the installation
material.
For use in direct sunlight, the
UV-resistant systems serve extremely
well, such as the Star-
Quick clips in conjunction with
steel armoured pipes or ribbon
clips for wind-proof montage
of lines, e.g. on cable support
systems.
Fastening elements from hotdip
galvanised steel, stainless
steel or aluminium are also
available in a great variety of
sizes.
14

The installation of modern photovoltaic systems constantly presents the
installation engineer with the task of laying the lines safely while conforming
to standards. The insertion of the energy lines in connection units
such as the inverter or the counter unit is also a subject for discussion.
It’s a question
of combination
With the OBO range of products,
you can be sure you will always be
equipped for any eventuality.
The sealing of entries for inverter
and distribution systems, which are
exposed to the effects of weather,
can be secured with the OBO cable
glands of the V-TEC VM series (Protection
class IP 68). The black-coloured
types are recommended for
outdoor use as these ensure less
UV radiation penetration.
If you have too few entries in the inverter,
or the screw connection is
too large, these problems can be
overcome by using the multi-way
seal insert or the reducing seal insert.
The multi-way seal inserts are
especially useful with the smalldiameter
photovoltaic lines.
