2. Important: The link between groups, categories
and zones is explained in the 1999/92/EC
directive. Note that this is a minimum directive.
Some EU countries may 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.
