Warning about dangerous electrical voltage!
If mains power is connected to the analogue inputs,
this results in destruction of the controller!
Malfunction due to interference!
All supply lines from and to the case controller must be shielded
(cable type: LiYCY)! If sensor cables are exclusively laid within the refrigerated case to be monitored
and sources of interference (e.g. parallel power lines) are not anticipated, then it is possible to
dispense with shielding. As a general rule, care should be taken to ensure that signal cables and
cables carrying mains voltage are routed in separate cable channels.
