6.4 Protective equipotential bonding/
earthing
Protective equipotential bonding establishes a
connection with good electrical conductivity be-
tween conductive bodies of electrical equipment
and the main equipotential bonding bar (main
earthing bar) of the building. (According to DIN
VDE 0100, bodies are touchable conductive parts
which, in contrast to the "active parts" of the
equipment, can only be live as a result of a fault).
This measure serves to protect against electric
shock and is standardised in IEC 60364-4-
41:2005 and DIN VDE 0100-410:2007-06.
The technical design for equipotential bonding is
standardised in IEC 60364-5-54:2011 and DIN
VDE 0100-540:2012-06.
f
Comply with applicable standards and country-spe-
cifi c regulations.
f
Use an equipotential bonding conductor made of
copper with a cross-section of at least 6mm².
DANGER
Danger to life due to electric current!
There is a danger to life if live components are
touched.
!
Disconnect the product from the power supply
at all poles.
!
Check that no voltage is present.
!
Secure the product against being switching
back on again.
!
Only install the product in dry indoor areas.
Since the circulation pump cannot be considered
electrically conductive, it is necessary to connect
the piping upstream and downstream of the
pump to the equipotential bonding bar. This can
be done outside and inside the station. Suitable
mounting points for earthing clamps inside the
station are shown in Fig. 19 on page 27.
f
Fit appropriate earthing clamps to the station's piping.
Earthing clamps are available as accessory.

f
Connect the earthing clamps to a suitable equipotential
bonding bar in the building using an equipotential
bonding conductor made of copper with a cross-section
of at least 6 mm².
