Carrying out an insulation test
1. Open all the separation points
1
of the system to be checked.
2. Place the insulation measuring device between the connection elem-
ent
2
and testing point
3
or the nearest fastening clip.
3. Apply the test voltage of the insulation measurement device of
500 V DC for ≥ 3 s.
4. Continue according to the result:

* Due to the ASE technology used (adaptive switching element), the
resistance value displayed on the insulation measuring device may vary.
