Table 7 High-Isolation Filter Modules - WAGO 750 Series Manual

Planning
No additional filter module is required for field supply with a nominal value different from
24 VDC.
No filter module is required for field supply different from 24 VDC.
Marine Applications per DNV
• Class A: all areas except bridge and open deck
• Class B: all areas including bridge and open deck
Applications with Isolation Monitoring
High-isolation (HI) versions of the filter modules are required for applications with isola-
tion monitoring.
