2.2.2 Operation in hazardous location or pumping flammable liquids
Application in explosion hazard areas or pumping flammable liquids the following points must be noted additionally:
► The operator must create an explosion protection document for his field of application. This document must
indicate the division of the explosive area into zones. Only devices of category 1 may be used in areas of
zone 0 and devices of category 1 or 2 in areas of zone 1.
