2.4 Operating conditions
The rho4.0 is designed for continuous operation (24 hours/day).
Unless stated otherwise in specific sections, these specifications apply:
Temperatures
Storage temperature:
D −25 °C to +70 °C
Ambient temperature
D +5 °C to +55 °C, monitored
Ambient temperatures apply to installation described in chapter 3.
Safety function
Temperature monitoring
The ambient air must not excess +55 °C. For the safety, a temperature
monitoring measures the temperature in the housing. At an ambient
temperature of +58 °C, the rho4.0 is brought into a safe state and shut
down.
