FEA-01 user's manual 7
Mechanical installation
The housing of the FEA-01 unit has two spring-loaded fasteners
for vertical or horizontal 35 × 7.5 mm DIN rail mounting. The
mounting rail must be earthed to a noiseless earth. If the rail is not
mounted on a properly earthed base, a separate earthing
conductor must be used. The conductor must be as short as
2
possible and its cross-sectional area must be 6 mm
at least.
Note: No solid copper conductor may be used (stranded wire
allowed only).
The unit should be mounted so that air can freely pass through the
ventilation holes in the housing. Mounting directly above heat-
generating equipment should be avoided.
Mounting an I/O extension module
To mount an I/O extension module, insert the plastic retaining clips
of the module (a) into the slots in the FEA-01 and fasten the screw
(b). Correct installation of the screw is essential for fulfilling the
EMC requirements and for proper operation of the module. For
more information, see the relevant user's manual.
