1 The upper ambient temperature limit depends on system configuration:
– space between pcb’s in a rack
– heat dissipation of neighbouring electronic circuits
– air flow
In any case the user must assure a case temperature of the module below 95
°C.
2 Storage at high temperatures may cause an acceleration of aging.
