5.4.4 Response to overtemperature
Operation at overtemperature reduces the module service life and can result in damage to the
module.
Causes
Cause of problems in the heat dissipation of the module can be, for example:
● Violation of the maximum permissible air intake temperature
● Free convection is not ensured (clearances are not maintained, pollution, convection is
prevented by cables)
● Impermissible mounting position of the module
