Siemens SIVACON User Manual

2.3 Ambient temperature
The ambient temperature category for most standard types is–40 / D. This means a max.
temperature of 55 °C, an average temperature over 24 hours of 45 °C, and the average
temperature in one year should not exceed 35 °C. The maximum casing temperature of 60 °C
must not be exceeded. Temperature is one of the main stress factors for polypropylene type
capacitors. Temperature has a major in󹪞uence on the useful life expectancy of the capacitor.
WARNING
The use of damaged devices may result in death, serious injury, or property damage.
Capacitors should not be used any longer in case of dents, mechanical or any other kind of
damage.
Check the integrity of discharge resistors before installation.
WARNING
Exceeding the maximum allowed temperature may set safety device out of operation. It
may result in death, serious injury, or property damage.
The maximum allowed temperature must not be exceeded.
DANGER
Hazardous voltage will cause death, serious personal injury, or equipment damage.
