1.1  Safety instructions

Make sure that any persons installing, taking into operation and 
operating the “temperature monitoring device Comem DTI/eDTI”:
•  Are technically qualified and competent.
•  Fully comply with these assembling instructions. 

Improper operations or misuse could cause danger to:
•  life and limb.
•  to the equipment and other assets of the operator.
•  to the equipment proper function.

TION MUST BE STRICTLY OBSERVED.  

THIS INFORMATION INDICATES PARTICU-
LAR DANGER TO EQUIPMENT OR OTHER 
PROPERTY OF THE USER. SERIOUS OR FA-
TAL INJURY CANNOT BE EXCLUDED. 

THE TEMPERATURE CONTROL UNIT 
COMEM DTI/EDTI MUST NOT BE INSTALLED 
NEAR SOURCES OF ELECTROMAGNETIC  
INTERFERENCE. 

INSTALLATION, ELECTRICAL CONNECTION 
AND FITTING THE DEVICE MAY ONLY BE 
CARRIED OUT BY QUALIFIED PERSONNEL 
AND ONLY IN ACCORDANCE TO THIS IN-
STRUCTION MANUAL.  
IT IS RESPONSIBILITY OF THE USER TO
