Permitted ambient temperature T dependent on load current I
4.1.2 Integrated protection mechanisms
Integrated protection mechanisms 4- ][Schutzmechanismen PS
The module has the following protection mechanisms:
 Infeed for module supply
– Polarity protection
– Voltage monitoring
– Transient voltage limitation
 Module supply
– Short circuit-proof
 Periphery supply
– Voltage monitoring (exceeding upper/lower limit)
The module registers the following errors:
 Start-up error
 Configuration error
 FS communication error
 Bus termination error
 Temperature error: too warm
 Overvoltage error
 Undervoltage error
 Error in the overvoltage protection diodes
