C.M.C. n.v. - Airmaster S1 installation guide – V1.2 – MANY0402A.00
A suitable UL508 branch circuit protection must be provided on the primary side
of the transformer. A supplemental fuse (in accordance with UL248 series) with a
rating of 1,6A ‘T’ type (slow blow) is obligated for the secondary side. In case of
doubt please contact the transformer supplier.
Please consult the text of the UL508A and/or UL508 standard for more
explanation regarding this item.
For the European market (CE)
The transformer or power supply must be in accordance with the current
applicable European directives (e.g. Low Voltage Directive and EMC directive).
This means that it must conform to the EN61558 standard
(
partly supersedes the
older EN60742 standard) for the particular application. Also applicable are
EN60204 (Safety of machinery - Electrical equipment of machines) and
EN60950. A CE marking must be on the device.
The Airmaster S1 is a class I equipment in which protection against electric
shock does not rely on basic insulation only, but which includes an additional
safety precaution in that accessible conductive parts are connected to the
protective earthing conductor in the fixed wiring of the installation in such a way
that they cannot become live in the event of a failure of the basic insulation.
In the case of a proper grounding or earth connection an isolating transformer
can be used. However, if the chance exists that the earth connection can be
disconnected when the equipment is under voltage, a safety-isolating
transformer must be used. Note that for EMC reasons an earth connection is
obligatory.
The transformer or supply must be suitable for use in a standard industrial
environment.
