Sub−base CPX−AB−4−M12x2−5POL (without metal thread) can
be combined with a screening/shield plate. Depending on
what you have ordered, this may already be fitted on the sub−
base.
Instructions on subsequent fitting of the screening/shield
plate can be found in section 1.3.2.
The electromagnetic compatibility can be improved with
screening/shield plates, e.g. in environments heavily sub
jected to interference or for analogue signals. For this pur
pose the screening/shield plates must be earthed at the flat
contact intended for this purpose as per DIN 46244 B2,8−1
(2.8 x 1 mm).
·
Connect the earth cable of the screening/shield plate
with low impedance to the functional earth connection
(FE) as per Fig.1/3.
Screening/shield plates lying next to each other are
connected together by spring clips and must not be
connected individually to FE.
If the intended plugs are used (see Accessories", appendix
A.8), the plug housing will be connected to functional earth
via the screening/shield plate by means of the spring con
tacts.
·
Before fitting the plugs screw the spring contacts as far as
possible onto the thread of the plug.
