Power Supply for Marine Applications

Use a separate power supply when operating the module in marine
applications!
When using the 750-632 module in marine applications, the requirements
described below must be respected. Non-compliance with these requirements
may lead to malfunctions due to conductive interference emission.
The system power supply must be filtered in the bus node. Therefore, the 750-
626 module must be used for system power supply.
An external power supply unit must be used when supplying the 750-632 module
with field-side power. The power supply unit must meet EMC 1 or EMC 2
requirements per IACS E10. This power supply unit can be used to supply
several 750-632 modules – but no other components or devices.
The field supply must be filtered in the bus node. Therefore, the 750-632 module
shall only be connected to the right side of the 750-624 Filter Module or to other
750-632 modules. Only a bus module without power jumper contacts (e.g.,
supply, filter or end module) shall be connected to the right side of the 750-632
module(s).
