Grounding Instructions
Safety Notes
Large surface shielding with
shielding material is not consi-
dered electrical equipment,
but „external conductive
parts“ in accordance with IEV
826-03-03 or IEV 195-06-11,
and therefore a new method of
DIN VDE 0100-100:2009-06.
Once the material is connected
to the potential equalization,
it automatically forms part of
the electrical system, and the
general technical rules and
regulations must be observed.
According to the latest state of
technology, it is important to
distinguish between the pro-
tective equipotential bonding
and the functional equipoten-
tial bonding. The purpose of
the protective equipotential
bonding (green/yellow cable) is
to avoid hazardous contact
voltage by immediately trigge-
ring the circuit breaker. The
purpose of the functional
equipotential bonding (trans-
parent cable) on large surface
shielding is to minimise the
emission of low frequency
alternating electrical fields, i.e.
to avoid leaking electrical
fields.
Grounding is only permitted in
buildings with TN-S, TT, and IT
systems. Under no circum-
stances implement grounding
in network configurations with
combined PEN conductors!
The installation of a fault current
circuit breaker (FI/ RCD) of
max. 30 mA is compulsory!
DIN EN 62305-3 (VDE 185-
305-3:2006-10) applies to
buildings with an external
lightning protection system.
Connection of Potential
Equalization
Ideally, the function equipoten-
tial bonding (FEB-) line should
be directly connected to the
FEB-busbar in the fuse box
with a 4 mm² cable .
Exemption if not feasible: The
FEB-line can also be connec-
ted to a „suitable protective
conductor or balancing line“.
In this case grounding is achie-
ved with a 2.5 mm² cable con-
nected to a protective conduc-
tor in the electric installation.
Typically this takes place in a
receptable / wall socket.
Metal tube systems or separate
grounding rods not connected
to the building potential equa-
lization are not really suitable.
In the case of network systems
with combined PEN conductors,
though, tube or rod grounding
is possible, however always
taking into account country
specific regulations.
Mounting of the Grounding
Point
One grounding point is needed
per continuously connected
area (such as one room with
walls, ceiling and - if so - floor).
It should be mounted at a point
of easy access close to the
earth connection.
Drill 6 mm holes. Take care not
to hit any cables if you‘re drilling
close to sockets or switches!
Grounding with Shielding Paint:
If need be, apply grounding
tape all across the site to be
painted.Then apply shielding
paint as described in the paint
instructions. Once the paint is
dry, the area underneath and
around the grounding plate
needs to be painted with a
second coat. Let dry.
Grounding with Nettings and
Fleeces:
Attach the material onto the
surface to be shielded with
an appropriate overlap. Apply
grounding tape underneath
or on top of the material as
defined in the corresponding
instructions. Let dry.
Re-drill the holes, insert do-
wels and fix grounding plate.
Mask the grounding plate - do
not cover with paint!
Apply normal wall paint, wall-
paper or plaster, always taking
into account the instructions
of the corresponding shielding
material.
Install grounding cables.
In the exterior please apply the
stainless steel grounding strap
ELB!
Grounding Tape (where
applicable)
To make sure there are no un-
grounded areas left or caused
subsequently by cracks for in-
stance at the point of transition
from one wall material to the
other (e.g. wood to plaster), it
is possible to apply an additio-
nal grounding tape. There are
different types of grounding
tapes for different applications:
Under paint: EB2
Pressure-sensitive tape with
non-conductive adhesive, i.e.
exclusively for application
underneath shielding paint.
Due to its strong adherence (10
N/cm) it can also be used on
difficult surfaces.
On or under all other materials:
EB1
Pressure-sensitive tape with
electroconductive adhesive for
a reliable connection between
the single sheets. Low adhe-
rence (3 N/cm). Difficult sur-
faces (such as gypsum plas-
terboards) need to be prepro-
cessed with a prime coat.
In the exterior please apply the
stainless steel grounding strap
ELB!
