Safety and protection features
| Insulation resistance | Min. 500MOhm | In the delivery state between input and output, measured with 500Vdc | 
| Min. 500MOhm | In the delivery state between input and Chassis Ground, measured with 500Vdc | |
| Min. 500MOhm | In the delivery state between output and Chassis Ground, measured with 500Vdc | |
| Min. 500MOhm | In the delivery state between output and DC-OK contacts, measured with 500Vdc | |
| PE resistance | Max. 0.1Ohm | Resistance between PE terminal and the housing in the area of the DIN rail mounting bracket. | 
| Output overvoltage protection | Typ. 31Vdc | In case of an internal defect, a redundant circuit limits the maximum output voltage. The output shuts down and automatically attempts to restart. | 
| Class of protection | I | According to IEC 61140 | 
| Degree of protection | IP 20 | According to EN/IEC 60529 | 
| Over-temperature protection | Not included | 
 | 
| Input transient protection | MOV (Metal Oxide Varistor) | For protection values see chapter “EMC” | 
| Internal input fuse | Included | Not user replaceable slow-blow high-braking capacity fuse | 
| Touch current (leakage current) | The leakage current, which is produced by the DC/DC converter itself, depends on the input voltage ripple and need to be investigated in the final application. For a smooth DC input voltage, the produced leakage current is less than 100µA. | |
