The name plate must be permanently attached to the product and must be in legible condition.
Any other or additional use is not considered proper or intended use and can lead to an annulment of the product guar-
antee. This includes:
– Mobile use
– Use in rooms where there is a risk of explosion
– Use in direct sunlight, rain or a storm or other harsh environmental conditions
– Outdoor use in environmental conditions that exceed the limits stated in the technical specifications >Environmental
data.
– Operation outside the specification intended by the manufacturer
– Overvoltage on the DC connection of over 1,100 V
– Device modification
– Standalone mode
2.2 Protection features
The following monitoring and protection functions are integrated in the device:
– 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 product 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
– ISO detection of a generator insulation fault.
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.
