Protection features

The following monitoring and protection functions are built-in:
– RCMU (Residual Current Monitoring Unit)
– Overvoltage conductor / varistor to protect the power semiconductors from high-energy transients on the
grid and generator sides.
– Device temperature monitoring system
– EMC filter to protect the inverter from high-frequency grid interference
– Grid-side varistors grounded to earth to protect the product against burst and surge pulses
– Anti-islanding detection according to the current standards.
– Isolation detection / residual current monitoring and disconnection function to detect isolation faults
NOTE
If the device is connected, the overvoltage conductors / varistors contained in the device have an impact on the
electrical system insulation resistance test as per HD 60364-6 / IEC 60364-6 Low-voltage installations- Part 6:
Verification.
IEC 60364-6 6.4.3.3 describes two options for this case. The first option is to disconnect devices with an over-
voltage conductor or, if this is not practicable, then the test voltage can be reduced to 250V.
