Temperature 10 to 55 C icing and condensation not allowed Humidity 25 to 8596 When the temperature controller is incorporated in a control panel make sure that the controller s ambient temperature and not the panel s ambient temper ature does not exceed 55 C The life of electronic equipment such as temperature controllers is influenced not only by the life determined by the relay switching count but also by the life of the electronic components used internally The service life of components is dependent on the ambient temperature the higher the ambient temperature becomes the shorter the service life becomes and vice versa For this rea son the service life of the temperature controller can be extended by lowering its internal temperature Gang mounting two or more temperature controllers or mounting tempera ture controllers above each other may cause heat to build up inside the tem perature controllers which will shorten their service life When mounting temperature controllers like this forced cooling measures such as a cooling fan for cooling the temperature controllers must be taken into consideration Prevent only the terminal block from being cooled Otherwise this may result in a measurement error 2 3 2 To Reduce the Influence of Noise To reduce induction noise the leads on the temperature controller s terminal block must be wired separately from large voltage large current power leads Also avoid wiring lead
