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 in an Ex classified area (see Figure 5). The ATEX/IECEx motor (Pos. 2b in Table 2)
comes delivered with special connectors and relevant 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. 10) and shown in Figure 2.
