10.2 Technical data of the G115D wall-mounted converter
Explanation
4 kHz (default); 2 kHz...16 kHz (in steps of 2 kHz)
Current derating as a function of the pulse frequency (Page 379)
When using fuses: 65 kA rms
You can find the data for further overcurrent protection devices on the Internet:
Branch protection and short-circuit strength according to UL and IEC
(https://support.industry.siemens.com/cs/ww/en/ps/27867)
5 kA rms
The converter can be operated with a type B 300 mA RCD.
• 180 V DC
Rated current: 0.8 A
–
– Disconnection on the DC side permits "fast" braking
• 400 V AC (optional, for wall-mounted converter only)
Rated current: 1 A

Explanation
STO, SIL2 / PL d / Category 3
STO fulfils the requirements of the following standards:
• SIL 2 according to IEC61508, part 1 to 3 (2010)
• PL d according to IEC61800-5-2 (2016)
• Category 3 according to ISO13849 part 1 (2015)
The function STO corresponds to stop category 0 according to IEC60204 (2005)
Response time: 20 ms
The response time of the Safe Torque Off function is the time between selecting
the function and the function becoming active.
Probability of failures:
• Probability of dangerous failure per hour: PFH < 25×10
PFH according to IEC 61800-5-2
• Probability of dangerous failure on demand: PFD < 25×10
PFD according to IEC 61508
Mission time: 20 years
You may not operate converters with integrated safety functions for longer than
the mission time. The mission time starts when the device is delivered. The mission
time cannot be extended. This is the case even if a service department checks the
converter – or in the meantime, the converter was decommissioned.
