Indications WEGA 1.2, WEGA 2.2

DANGER!
High voltage! Danger! Verify safe isolation from supply without any doubt!
Possible sources of failure:

- Defective voltage indicator (or device for function testing of the coupling section)
- Maloperation of the voltage indicator (or device for function testing of the coupling
section)
Use only voltage indicators or devices according to EN 61 243-5 / IEC 61 243-5 /

VDE 0682-415 to test the function of the coupling section. (The interface conditions have
not changed as against the old standard VDE 0681 Part 7; the corresponding indicators can
still be used.)
