FLEX I/O Isolated Output HART Analog Module
Publication 1794-IN120D-EN-P - September 2015
ATTENTION:
FLEX™ I/O is grounded through the DIN rail to chassis ground.
Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
ATTENTION:
To reduce susceptibility to noise, power analog modules and
digital modules from separate power supplies.
ATTENTION:
Do not exceed a length of 3 m (9.8 ft) for DC power cabling.
ATTENTION:
To comply with the CE Low Voltage Directive (LVD), all
connected I/O must be powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
WARNING:
If you insert or remove the module while backplane power is on,
an electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
WARNING:
If you connect or disconnect wiring while the field-side power is
on, an electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
