3. Commissioning, earthing and self-test
3.1 Unwind the grounding line
Loosen the lock on the drum and unroll the cable completely or so far
that the test point can be easily reached from the earthing point.
Note:
For quick operation, both ends of the cable (test device and clamp)
are unwound from the drum at the same time and are fixed in the
middle (at 15 m).
Note:
For better handling, the line can be separated from the drum.
The middle is marked by a loop.
3.2 Establish ground connection
Connect the clamp to the earth potential.
For example, the following can be suitable as ground contact:
•
heating pipes made of copper
•
equipotential bonding bars
•
lightning rod
Incorrect, not connected to earth potential ground connection can prevent dangerous voltages from
being displayed! Checking with the self-test (3.4) is absolutely necessary!
•
protective conductor
•
earthing stakes driven into the moist soil
•
lampposts (unpainted) ...
