8.2.1 Ground test
For commissioning, carry out a ground test (check of the protective bonding
impedance) in accordance with IEC 61010-1. Observe the following informa-
tion when testing:
▪ Test current: 2 times the rated current of the overcurrent protection device
in the supply line.
▪ Test duration: 1 minute for each measurement point.
▪ The measured voltage between the measurement point and the protective
conductor must be less than 10 V.
To carry out the ground test, proceed as follows:
► Apply the test current at the grounding terminal of the G1 PULS DIMEN-
SION QS3.241 assembly using a constant current source and measure
the voltage between the measurement point and the protective conductor.
ð
The measured voltage must remain less than 10 V for a period of
1 minute.
