With OBO precision surge protectors, surge pulses
are limited by Transzorb diodes. The devices are
earthed via powerful gas discharge arresters.
Decoupling with respect to the basic and precision
protection is ensured if the line length between basic
and fine protection is at least five metres. Precision
protection devices should always be installed directly
at the equipment to be protected.
Sensitive electronics and valuable data files are only
secure if the building where they are kept is well
protected from surges. OBO offers a comprehensive
range of proven and reliable systems, devices and
components for every area of lightning and surge
protection. To make it easier to assign the data line
protection devices to the respective application, they
are divided into three classes. Colours and clear
designations identify devices for basic protection
(red), combined protection (blue) and precision
protection (green).

Surge protection for analog telecommunication lines
Connection to the Internet via 56k modems means
that analog telecommunication installations are also
more prone to damage due to partial lightning currents. Several levels of measures are needed to protect these installations: in addition to precision protection at the terminal equipment itself, which protects
communications equipment from residual energy and
from voltages coupled-in by inductance and capacitance, protection devices capable of diverting partial
lightning currents should also be installed where the
wiring enters the building.
Devices that are particularly suitable for the protection
of analog telecommunications equipment are surge
protectors RJ11-Tele/4... and RJ45-Tele/4.... The
trouble-free operation of these devices has been certified by BAPT Test Report No. 118664640-1-2/97.
Example 1: Where a building has no external lightning
protection installation, a surge caused by a distant
lightning strike, for example, would be coupled-in via
the telecommunications installation as well. Surge
voltages may also be coupled inductively and capacitively on to the internal wiring. However, since the partial lightning energy is likely to be low, it is sufficient to
provide a surge protector for lightning protection zone
LPZ 1 → 3, which is installed at the terminal device.
Surge protector RJ11-Tele/4-F would be suitable for
the case of Example 1. This device is suitable for the
protection of analog fax machines, modems and telephones (four wires protected).
Example 2: A building with an external lightning
protection installation (LPZ 0) is also threatened by
direct lightning strikes to the lightning protection installation. Partial lightning energies are reliably
diverted by using a combination device of type
SC-Tele/4-C-G (basic and precision protection
LPZ 0 → 3) or a basic protection device TKS-B (basic
and precision protection LPZ 0 → 2). In addition, a
precision protection device such as RJ11-Tele/4-F
or ASP-Tele/4, filters out surge voltages that may be
coupled on to the telecommunication line by induction
or capacitance.
Example 3: Another way of protecting sensitive terminal devices from partial lightning currents is to use
a combination protection device (basic and precision
protection device LPZ 0 → 3) at the terminal device.
However, with this variant it is important to realise that
partial lightning energies travel as far as just before
the terminal device, and may therefore be coupled on
to neighbouring wiring. Suitable devices for combination protection are SC-Tele/4-C-G (screwless terminals) and RJ11-Tele/4-C (modular plug).

Surge protection for ISDN and DSL installations
ISDN and DSL installations allow fast transfer of large
amounts of data. The drawback is that surges can also
rapidly reach the terminal device and damage computer equipment. The danger can be overcome by balanced use of basic and precision protection devices.
Basic surge protectors where the data lines enter the
building divert all harmful partial lightning currents.
Precision surge protectors filter out capacitively and
inductively coupled-in voltages directly at the terminal
device. Surge protector RJ45-ISDN/4-C-G is especially
well suited for use in ISDN installations, having gained
certification of trouble-free operation in BAPT Test Report No. 1284/55551-3/96.
Example 1: In buildings without external lightning
protection installation, a surge caused by a distant lightning strike, for example, is coupled-in via the ISDN or
DSL line. Surge voltages may also be coupled inductively and capacitively on to internal wiring. However,
since the partial lightning energy is likely to be low, it is
sufficient to provide a surge protector for LPZ 1 → 3,
installed at the terminal device.
Example 2: A building with an external lightning protection installation is also threatened by direct lightning
strikes to the lightning protection installation. Partial
lightning energies are reliably diverted by using a com-
bination device of type SC-Tele/4-C-G before the NT-S0
interface or a basic surge protector TKS-B (basic and
precision protection LPZ 0 → 2). A precision surge protector installed directly at the terminal device, e.g.
RJ45-ISDN/4-F or ASP-Tele/4 for ISDN installations and
RJ45S-ATM/8F for DSL modems, additionally filters out
surges that may be coupled-in inductively or capacitively. Check with the network operator concerned
whether it is permissible to install a surge protector before the NT-S0 interface.
Example 3: Another way of protecting sensitive terminal
devices from partial lightning currents is to use a combination protection device RJ45-ISDN/4-C-G (only for
ISDN installations) (basic and precision protection device LPZ 0 → 3) at the terminal device. However, with
this variant it is important to realise that partial lightning
energy travels as far as just before the terminal device,
and may therefore be coupled on to neighbouring
wiring.
Example 4: This example shows combination surge protector RJ45-ISDN/4-C-G (only for ISDN installations),
installed directly behind the NT-S0 interface. The precision surge protector RJ45-ISDN/4-F connected in
series after it additionally filters out inductive and/or
capacitive surges.

Surge protection for Ethernet 10Base2 (Cheapernet)
and Ethernet 10Base5 (yellow cable)
A system widely used for in-house networks is coaxial
Ethernet. There are two variants of this bus system:
Ethernet 10Base2 uses BNC connectors, Ethernet
10Base5 uses N connectors. For precision protection,
all computer outputs (e.g. server, network cards, etc.)
should be fitted with surge protectors. This provides
the computer installation with perfect surge protection. Networks that extend throughout an entire building can only be protected from partial lightning currents by protective devices installed where wiring
enters the building.
Example 1: Where a building has no external lightning protection installation, a surge caused by a
distant lightning strike, for example, may be coupled
in via the Ethernet cabling installation. Surge voltages
may also be coupled inductively and capacitively on
to internal wiring. However, since the partial lightning
energy is likely to be relatively low, it is sufficient to
provide a medium or precision protection device
for lightning protection zone LPZ 1 → 3 (Ethernet
10Base2 system: medium and precision protection
device KoaxB-E2/MF-F).
Example 2: A building with an external lightning
protection installation (LPZ 0) is also threatened by
direct lightning strikes to the lightning protection installation. Partial lightning energies are reliably diverted by using a combination device of type
KoaxB-E2/MF/C (LPZ 0 → 3, for Cheapernet) or
KoaxN-E5/MF-C (for yellow cable) connected at the
terminal device. However, with this variant it is important to realise that partial lightning energies travel as
far as just before the terminal device, and may therefore be coupled on to neighbouring wiring.
Example 3: A better solution is separate two-stage
surge protection. Basic surge protectors
KoaxB-E2/FF-B and KoaxN-E5/FF-B (LPZ 0 → 2) divert the partial lightning currents directly at the infeed
point. Precision surge protectors KoaxB-E2/MF and
KoaxN-E5/MF-F (LPZ 1 → 3) filter out residual surges.
Example 4: Ethernet systems are usually used
within building systems. In these cases, the necessary surge protection is limited to the elimination of
inductively and/or capacitively coupled surges due
to a lightning strike on the external lightning protection
system or a nearby strike, on a tree for instance.
Me-dium and precision protection devices KoaxBE2/MF-F and KoaxN-E5/MF-F are suitable for these
applications.

Surge protection for Ethernet Twisted Pair
(BaseT, Cat. 5 and Cat. 6)
Ethernet Twisted Pair has become the established
system for computer networks in buildings. In this
system, which is used mainly for in-house solutions,
UTP5 RJ45 connectors are generally used. Precision
surge protectors installed directly at the terminal
equipment protect against capacitively and inductively coupled-in surges. If the surge protectors are installed at both ends of the copper lines – at the
server, at the hub and at the network card – damage
to the computer system by surges can in most cases
be prevented. For networks that extend over more
than one building, only suitably dimensioned surge
protection devices installed where the lines enter the
buildings provide complete protection.
Example 1: Where a building has no external lightning protection installation, a surge caused by a distant lightning strike, for example, may be
coupled -in via the Ethernet cabling installation. Surge
voltages may also be coupled inductively and capacitively on to internal wiring. However, since the partial
lightning energy is likely to be relatively low, it is sufficient to install a surge protector for LPZ 1 → 3 (medium and precision surge protector RJ45S-E100/4-F).
Example 2: A building with an external lightning protection installation (LPZ 0) is also threatened by direct
lightning strikes to the lightning protection installation.
Partial lightning energies are reliably diverted by
using a combination device of type RJ45S-E100/4-C
(basic and precision protection LPZ 0 → 3) at the terminal device. However, with this variant it is important
to realise that partial lightning energies travel as far as
just before the terminal device, and may therefore be
coupled on to neighbouring wiring.
Example 3: A better solution is separate two-stage
surge protection. Basic surge protector
RJ45S-E100/4-B (LPZ 0 → 2) diverts the partial lightning currents directly at the infeed point. Precision
protection device RJ45S-E100/4-F (LPZ 1 → 3) filters
out the remaining surges.
Example 4: Ethernet cabling is usually used within
building systems. In these cases, the necessary
surge protection is limited to the elimination of inductively and/or capacitively coupled surges due to a
lightning strike on the external lightning protection
system or a nearby strike, on a tree for instance. Medium and precision surge protector RJ45S-E100/4-F
is suitable for these applications.
Note: in protector RJ45S-ATM/8-F, all eight cores are
connected.

Precision protection devices SD and ASP
SD series: SD surge protectors are used to protect
data, telecommunication and bus lines fitted with
D-Sub connectors. The Transzorb diode protection
circuit limits incoming transients to harmless values.
ASP series: Data lines with two or four cores can be
protected from surges with protectors from the ASP
series. A quick-response suppression diode circuit
reliably prevents destruction of the connected devices.
Mounting
SD series: SD series adapter devices are installed
simply by connecting them between the data line and
the device to be protected.
ASP series: The screwless terminals of series ASP
precision protection devices allow quick, problem-free
installation into the line immediately before the device
to be protected. Every ASP surge protector comes
with a piece of self-adhesive burr tape for
fixing. To achieve optimum surge protection, the earth
84
wire of the ASP surge protector should be connected
by the shortest path with the earthed metal chassis of
the device to be protected.

Function and application
Lambda Protector 7/16
DS-N, DS-BNC and S-UHF are coaxial surge protectors with a high surge current capacity, suitable for
use at zone interface 0 to 2. They are designed primarily for the RF region. Their low insertion loss and
low-capacitance design also make these surge protectors ideal for very high frequency ranges. The voltage limiting component is a gas discharge tube with a
high power handling capacity.
The λ/4-protectors of type LP 7/16 act as narrow-band
filters. They pass only a narrow frequency range.
Other frequencies are short-circuited and diverted. In
surge protectors of this design, a direct short-circuit is
established between the inner and outer conductors.
This short-circuit takes the form of a coaxial line of
precisely defined length, an electrical wavelength of
one-quarter of the wavelength (λ/4) of the frequency
to be transmitted.
Mounting
The coaxial surge protectors are inserted into the line
at zone interface 0 to 2. To simplify installation, the
modules can be supplied in different combinations of
plug and socket.

Note: a set of adapters suitable for the DS-BNC m/f
device is available for F-connections.
