*)   The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime 
expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the 
capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years 
(131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices. 
**)  MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a 
device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product. 
 
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that 
statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not be determined if the failed unit 
has been running for 50 000h or only for 100h.
