CAUTION!
Take safety precautions.
Observe the safety rules – DC voltage present!
WARNING!
Set DC disconnector of the inverter to level 0 and insert the inverter in the wall brack-
et.
Installing the inverter means that voltage is now also present at the inverter

Example: Measurement of the ground conductor re-
sistance
(A) – release on power stage set cover
- If necessary, the wall bracket must be lightly
scratched in order to penetrate the Eloxal or powder
layer
- The resistance must not exceed 0.3 *)
*) These requirements comply with DIN VDE 0701-0702 and ÖVE/ÖNORM E8701-1. Also
refer to the applicable requirements and standards in your country.
Ground conduc-
tor current
Preparation
- Measurement should only be carried out once the ground conductor resistance test
has been carried out successfully
- Direct process: The device must be insulated from ground. There must be no addition-
al connections to the ground potential (e.g. data leads, assembly)
- Remove conductive objects from the housing
- Mount missing housing parts.
WARNING!
An electric shock can be fatal.
During the measurement, there are voltages at the inverter.
Once the inverter has been connected, it must be put back into operation. For the mea-
surement, the inverter must feed into the grid, as failure to do this will lead to an incorrect
measurement result.
