CONDITIONS OF USE
PERMITTED USE
For safety reasons the instrument must be
installed and used according to the
instruction provided and in particular,
under normal conditions, parts bearing
dangerous voltage levels must not be
accessible.
The device must be adequately protected
from water and dust as per the application
and must also only be accessible via the
use of tools (with the exception of the
frontlet).
The device is ideally suited for use on
household appliances and/or similar refrig-
eration equipment and has been tested
with regard to the aspects concerning
European reference standards on safety. It
is classified as follows:
• according to its manufacture: as an auto-
matic electronic control device to be
incorporated by independent mounting;
• according to its automatic operating fea-
tures: as a 1 B-type operated control type;
• as a Class A device in relation to the cat-
egory and structure of the software
UNPERMITTED USE
Any other use other than that permitted is
de facto prohibited. It should be noted
that the relay contacts provided are of a
practical type and therefore subject to
fault. Any protection devices required by
product standards or dictated by common
sense due to obvious safety reasons should
be applied externally.
