The link between groups, categories and zones is
explained in the 2014/34/EU Directive. Please note
that this is a minimum directive. Some EU countries
might therefore have stricter local rules. The user or
installer is always responsible for checking that the
group and category of the pump correspond to the
zone classification of the installation site.
