Integrated protection mechanisms

When the PSSu E F PS1(-T) or PSSu E F PS2(-T)(-R) is used to supply the system, the
module supply is buffered for 20 ms if the supply voltage is interrupted.
The module has the following protection mechanisms:
Protective separation between both relay contacts (see Technical details)
}
Protective separation between both relay contacts and the periphery supply as well as
}
the module supply, in accordance with DIN VDE 0110 overvoltage category 2 in a pro-
tected industrial network
Temperature monitoring
}
The module provides the following diagnostic data:
Start-up error
}
Configuration error
}
ST communication error
}
Bus termination error
}
Temperature error: too warm
}
Temperature error: too hot
}
