Power Supply Concept in Marine Applications
The appropriate filter module is required when using Ex i I/O modules in
marine applications!
Power supply to the Ex i supply module shall be provided via the appropriate
filter module when using Ex i I/O modules in marine applications! Modules
approved to category EMC1 (marine applications): 750-626 or 750-626/020-000.
Modules approved to category EMC2 (marine applications): 750-626,
750-626/020-000, 750-624 or 750-624/020-000.
