Use of the device

Permitted use

For the purpose of safety, the control device 
will have to be installed and used according 
to the instructions provided and, in particular, 
in normal conditions, parts with dangerous 
voltage must not be accessible. The device 
must be protected from water and dust and 
must also be only accessible by means of a 
tool. 
According to the reference regulations, the 
device is classified: 
• According to the construction as an auto-
matic electronic control device to be added 
with independent assembly or to be integrat-

ed; 
• According to the characteristics of the auto-
matic operation as type-1 action control 
device with regard to the manufacturing tol-
erances and drifts; 
• As class 2 device with regard to the protec-
tion against electrical shocks; 
• As class A device with regard to the software 
class and structure. 

Non permitted use

Any different use from the permitted one is 
forbidden.
It should be noted that, the relay contacts 
are of the functional type and are subject to 
faults; because they are controlled by an elec-
tronic part they can short-circuit or remain 
open. Possible protection devices according 
to the provisions of the product regulation 
or suggested by common sense, referring to 
obvious safety needs, must be implemented 
outside of the instrument. 

Liability and residual risks

The producer is not liable for possible damag-
es arising from: 
• installation/use different from the expected 
ones and, in particular, dissimilar to the safety 
prescriptions according to the provisions or 
the regulations in force and/or to the ones 

contained herein; 
• installations that do not ensure adequate 
protection against electrical shocks, water 
and dust in the assembly conditions; 
• installations that allow access to dangerous 
parts without the use of tools;
