WAGO I/O System 750
750-482/000-001 2AI 4-20mA HART NAMUR NE43
Power from SELV/PELV power supply only!
All field signals and field supplies connected to this I/O module (750-482/000-
001) must be powered from SELV/PELV power supply(s)!
Ensuring Immunity to Interference
Place a field-side power supply filter (surge) (750-624/020-001) before the HART
I/O module to ensure immunity to interference!
Ensure proper contact with the DIN-rail!
Proper electrical contact between the DIN-rail and device is necessary to
maintain the EMC characteristics and function of the device.
Replace defective or damaged devices!
Replace defective or damaged device/module (e.g., in the event of deformed
contacts).
Protect the components against materials having seeping and insulating
properties!
The components are not resistant to materials having seeping and insulating
properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for
handling devices/modules.
Clean only with permitted materials!
Clean housing and soiled contacts with propanol.
Do not use any contact spray!
Do not use any contact spray. The spray may impair contact area functionality in
connection with contamination.
