Contact Current - Fronius Symo Series Service Manual & Spare Parts List

Examples for measuring the ground conductor current
When carrying out the measurement (direct or differential current process), the ground
conductor current must not exceed the limit value of 3.5 mA **).
**) These requirements relate to DIN VDE 0701-0702 and ÖVE/ÖNORM E8701-1. In ad-
dition, individual national requirements and standards must also be observed.
