2.2.3 ATEX / IECEx System Configuration

Together with the standard pump head and controllers an ATEX / IECEx certified motor allows installation of
motor and pump head within an Ex classified area (see Figure 5). The ATEX / IECEx motor (Pos. 2b in in
Table 2) comes delivered with special connectors and according extension cables (Pos. 5a and 5b in Table
3). One option to lead the cables outside of the classified area is an Ex certified cable sealing system as
listed in Table 4 (see Pos. 8) and shown in Figure 2.
