Example: Measurement of the ground conductor re-
sistance
(A) – release on power module lid
- If necessary, the mounting 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
-
Only perform the measurement if a ground conductor resistance test has been carried
out successfully
-
Direct Method: The device must be isolated from the ground. No other connections to
the earth potential are permitted (e.g. data cables, fitting, etc.)
-
Remove conductive objects from the housing
-
Mount missing housing parts.
Once the inverter has been connected, switch it back on. The inverter must be feeding en-
ergy during the measurement to avoid unreliable results.
Only the leakage currents that occur at grid frequency may be included (50–60 Hz function
of ammeter). High-frequency leakage currents distort the measurement results *).
*) These requirements comply with DIN VDE 0701-0702 and ÖVE/ÖNORM E8701-1. Also
refer to the applicable requirements and standards in your country.
There are two methods that may be used to measure the ground conductor current:
-
Direct Method: Device must be completely isolated and must not exhibit any links to
another earth potential
-
Differential current method:
The measurement can be taken on the inverter (loop outside the device) or in the distribu-
tor. When taking the measurement in the distributor, ensure that there are no live conduc-
tors in the immediate vicinity and that no other consumers are connected to the same
circuit.
WARNING!
An electric shock can be fatal. During the measurement, there are
voltages at the inverter.
