1 Scope
This European Standard specifies requirements and provides recommendations for the
design and installation of connections (bonds) between various electrically conductive
elements in buildings and other structures, during their construction or refurbishment,
in which information technology (IT) and, more generally, telecommunications equipment
is intended to be installed in order to:
-
a) minimize the risk to the correct function of that equipment and interconnecting cabling from electrical hazards;
-
b) provide the telecommunications installation with a reliable signal reference – which may improve immunity from electromagnetic interference (EMI).
The requirements of this European Standard are applicable to the buildings and other
structures within premises addressed by EN 50174‑2 (e.g. residential, office, industrial and data centres) but information given in
this European Standard may be of assistance for other types of buildings and structures.
NOTE Telecommunications centres (operator buildings) are addressed by ETSI/EN 300 253.
This European Standard does not apply to power supply distribution of voltages over
AC 1 000 V.
Electromagnetic compatibility (EMC) requirements and safety requirements for power
supply installation are outside the scope of this European Standard and are covered
by other standards and regulations. However, information given in this European Standard
may be of assistance in meeting the requirements of these standards and regulations.
