Protection Features - Kaco blueplanet 92.0 TL3 US Manual

Manual
The device is intended for indoor and outdoor applications and may only be used in countries for which it has been ap-
proved or for which it has been released by KACO new energy and the grid operator.
Operate the device only with a permanent connection to the public power grid. The country and grid type selection must
be commensurate with the respective location and grid type.
For grid connection, the requirements of the grid operator must be implemented. In addition, the authorisation to con-
nect to the grid may be subject to approval by the responsible authorities.
The requirements of the grid operator must be met for grid connection to take place. The permission of the relevant au-
thorities may also be required in order to secure authorisation to connection to the grid.
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:
– Use of a distribution system that is not described (grid type)
– Use of sources other than PV-strings.
– 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 > [See sec-
tion 4.3} Page 17].
– Operation outside the specifications prescribed by the manufacturer
– Overvoltage of more than 1500 V at the DC connection
– Device modification
– Standalone mode

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 side
– 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- und Surgeimpulsen
– Anti-islanding detection according to the current standards.
– IMI (Isolation Monitoring Interrupter) 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.

WARNING! The device is not intended for use in residential areas and cannot ensure adequate
protection of radio reception in such environments.
