CB 752 – User's Guide (Version 1.01)
Caution
Danger of explosion when replacing with wrong type of battery. Replace only with the same or equivalent
type recommended by the manufacturer. The lithium battery type must be UL recognized.
Do not dispose of lithium batteries in general trash collection. Dispose of the battery according to the
local regulations dealing with the disposal of these special materials, (e.g. to the collecting points for

10.2.
Protection against Overheating
The system comes with a protective function against overheating.
The implemented protective function against overheating will turn off the system when the specified maximum
environmental temperature (+60 °C) is exceeded during operation (caused by external influences) and the internal
temperature has reached 85 °C.
For the CB752 platform:
A temperature value of 85°C at the internal temperature sensor equates to an environmental
temperature of 65 °C.
Any unsaved data will be lost when the system is switched off by the protective function against
overheating.
The device turns on automatically and performs a system start as soon as the internal temperature
decreases to 70 °C.
