The basic requirement for the secure operation of all electrical systems in a data centre are a functional earthing system and equipotential bonding. By the implementation phase, everything must be right – retrospective corrections are almost impossible.
Note on standards: for the installation of earthing systems and equipotential bonding networks for buildings, DIN 18014 and DIN EN 50310 apply, for example. In conjunction with lightning protection systems taking an LEMP concept into account, the requirements of DIN EN 62305-3 and -4 must also be heeded.
