C.M.C. n.v. - Airmaster S1 installation guide – V1.2 – MANY0402A.00
If only low voltage limited energy circuits are connected to the Airmaster S1 it is still
necessary to earth the unit to fulfill the electromagnetic compatibility demands.
The enclosure must be earthed at all times.
Low voltage (low current, limited energy) wires must be separated from the power
wires.
CMC disclaims any warranty in case the Airmaster S1 has been opened or repaired by
an unauthorized person.
5. Electromagnetic compatibility
The enclosure is an important part of the protection of the electronics against
electromagnetic interference. Also the radiation of electromagnetic energy is shielded
by the enclosure. Therefore it is necessary to earth the enclosure with a very short wire
to the nearest earthed metal part. We advise a maximum length of 20cm. Use a
stranded wire with at least a section of 1.0mm
2
.
The electromagnetic compatibility of the unit cannot be guaranteed when the unit is
opened.
The use of shielded cables, especially for analog inputs and digital communication is
highly recommended in order to have a correct EMC installation.
It is the responsibility of the user to design the machine or installation to which this
equipment is to be fitted according to the rules of a good EMC installation.
