8.31. TROUBLESHOOTING
This product has been designed so that a self-test can be carried out.
The result of this self-test is visible in the STATUS page of the Maintenance Interface:
Fig. 101 - Statuses page (Maintenance Interface)
Refer to the respective manual.
8.32. DIELECTRIC STRENGTH AND LEAKAGE CURRENT TEST
The inverters have an integrated EMC filter. As a result, they have a leakage current to earth. If the leakage current creates
compatibility problems with your installation (residual current device or other), you can limit it by deactivating the Y-capacitors
as shown below. In this configuration, the device does not meet the EMC requirements according to IEC 61800-3.
Use the following instructions
20
to configure the inverter for operation on an IT network or a grounded impedance network.
1. Remove the power terminal cover;
2. The switch is factory set to the position shown in detail 1;
3. To disconnect the built-in EMC filter, set the switch to the position shown in detail 2;
4. Replace the front cover.
