The shielded cavity wall boxes are special metal vacuum-
coated cavity wall boxes for the reduction of low-frequency
alternating electric elds. The metal coating is on the
outside of the box and is provided with a riveted 1.5 mm²
potential equalisation wire. This is connected with box
terminals up to the functional equipotential bonding bar.
The shielded cavity wall boxes are preferably used in new
buildings and for retrotting existing conventional cavity
wall boxes. Due to the low-frequency eld propagation
in wooden or wooden post-and-beam buildings, it is
extremely important to equip the entire house with shielded
boxes and shielded installation cables. In retrospect,
shielding of these elds is hardly, if at all, possible. This is
particularly useful for renovations in sensitive areas such
as bedrooms, children‘s rooms, computer server rooms
or hospitals and in combination with shielded cables.
The shielded cavity wall boxes are also frequently used
to supplement a high-frequency shielding measure
in order to avoid potential gaps in the shielding
surface in the area of the sockets and switches.
In order to maintain the function of airtight walls,
standardised windproong inserts available
on the conventional market can be used.
Wiring in shielded boxes must always be carried
out according to VDE guidelines (functional
equipotential bonding). Further information on
this can be found in our technical data sheet and
at www.funktionspotentialausgleich.de.

Shielded (building-safe) electrical installation:
To minimise the emission of low-frequency
alternating electric elds, shielded installation
cables and shielded equipment boxes are used.
For the shielding of the components to be eective, they
must be included in the potential bonding. A distinction is
made between protective and functional potential bonding.
Denition of protective equipotential bonding:
(PE, green-yellow) serves protective purposes
and is intended to prevent dangerous touch
voltages as well as to ensure the rapid tripping of
protective devices (e.g. circuit breaker / fuse).
Denition of functional potential bonding:
(FPA) is used to minimise low-frequency alternating
electric elds in shielded installations. In this case,
the connection wires of the coated accessory boxes
are routed to the FPA rail with the shielding wires
(SB) of the shielded installation cables (no further
connection to a protective earth conductor). PE and
FPA are only connected to the main earthing bar.
To avoid confusion with the protective conductor (PE), the
shielding wire (SB) must be insulated or marked magenta
(pink/pink) according to DIN EN 60445 (VDE 0197).
Conditions:
• Solid foundation earth electrode
underneath the moisture insulation
• Application of the TN-S or TT system
• Placing shielded installation cables in a
star conguration as far as possible
• Use of plaster and cavity wall device
boxes in shielded design
• Residual current device with a rated
dierential current IN ≤ 30 mA.
• Include all shielded end circuits for sockets, lamps
and shielded distribution and main circuits.
Distributor:
Step 1: Distribution box
Use protection class I distribution box (metal housing and
metal door) to dissipate the alternating electric elds.
If no distribution box or sub-distribution box with metal
housing is available, mount a metal plate (20 cm larger
all around than the distribution box) under the box. In
the case of plastered-in distribution boxes, work a ne
metallic mesh into the wall cut-out. Connect the metal
plate or the metal mesh properly to PE with ≥ 4 mm²
cross-section. Plastic doors do not allow shielding.
Step 2: Separate busbar
for protective potential bonding PE (green-yellow) and
functional potential bonding FPA (shielding wire).

Safety!
All work on electrical devices and electrical
systems must be carried out by a qualied be
carried out and checked by a qualied electrician
or under their direction and supervision!
Attention: For all work on the electrical
installation, always disconnect the mains
safely rst and also check it!
Mark functional potential bonding for clarication. Connect main earthing bar to
PE as usual, connect busbar FPA and busbar PE with ≥ 4 mm² cross-section.
In shielded installation cables, an aluminium foil is wrapped
around the cores to shield the alternating electrical elds.
A bare shielding wire (SB) is incorporated
for contacting the foil.
Remove the aluminium foil when stripping the cable.
Connect the shielding wires and the green-
yellow wires (PE) separately to the respective
busbars, otherwise wire the wires as usual.
Step 3: Wire shielded installation cables

Shielded appliance outlets have a connecting
wire magenta (pink) insulated, with connection
to the metallic outer coating.
This connecting wire is connected to
the FPA in the distribution box.
To do this, insert the magenta (pink) insulated wire
and the magenta (pink) insulated connection of
the device socket into the socket terminal.
Do not use unshielded cables with shielded wall outlets!
Step 6: Connect box terminals

Device sockets:
The device boxes (plaster or cavity wall design) are
vapour-plated with a conductive metal vacuum coating
to shield the alternating electric eld and are provided
with a connecting wire (transparently insulated).
Step 5: Insulating tube magenta (pink)
Insulating hose according to EN DIN 60445 (VDE 0197) available from Biologa
Danell: ISO-F-FPA - Art.No.: 41-9062 - 760201- magenta - Ø 3,5 mm - Length: 10
Meter
Step 4: Labelling FPA
The labelling eld „Functional potential bonding“
should be attached to the circuit distributor. It
contains notes on the shielded electrical installation
as well as the respective specialists.
Available to cut o in the FPA yer and to print and
cut out following these notes (size DIN A6).
Shielded cables and/or electrically conductive
cables and/or electrically conductive wall
surfaces are connected.
The shielding wires of the cables as well as
the connection of the wall surfaces are con-
nected to the protective conductor rail. If this
connection is loosened, the function of the
shielding is cancelled.
To increase personal and property protection,
all shielded lines and wall surfaces are routed
via a residual current circuit breaker with a
rated differential current ≤ 30 mA.

Specics:
Attention: please note diusion barrier in
the outer walls of wooden houses!
If no pre-wall installation level is available, there is the
option of a windproof insert (among others). Please ask the
timber house supplier! Otherwise, moist interior air may
penetrate the insulation layer and condensation may occur.
When opening the side tunnel exit of the
cavity wall cans, apply knife or chisel from
the inside and cut out, do not press.
Caution when working below living room
temperature, material becomes brittle.
