General information
NOTE
HT
Observe the operating instructions for the device, this manual and the application note for the
hy-sys
software for standby power operation. For standby power operation, an earthing point is
required that remains functional in the event of a grid failure.
In this application note, the product "blueplanet hybrid 10.0 TL3" is referred to as the device for ease of reading.

Intended use
The blueplanet hy-switch (hy-switch) serves as an all-pole disconnection point from the public grid for standby power
operation in the house installation. The grid disconnection takes place via bistable relays.
The switching position must be checked after the changeover to reliably ensure all-pole disconnection. Only then can
the standalone grid be connected by the blueplanet hybrid inverter.

Safety
DANGER
Touching the live connections will result in severe injury or death!
Installation and commissioning must only be carried out by suitably qualified technicians.
The following measures are mandatory for safe operation:
an automatic circuit breaker with 20 A (4-pole) must be installed in the connection line of the
device to the house grid in order to be able to safely disconnect and protect the device.
an RCD type B with 30 mA must be used. The installation must be carried out professionally and
the function must be checked before commissioning (see Figure 1).
Before working on the AC side, the device must be switched off (see operating instructions) and
disconnected by the circuit breaker. For safety reasons, a
waiting time of
2 minutes
must be
observed.
The PE connection of the
hy-switch
must be connected to the house earthing. It must be ensured
that the storage system has a safe connection to earth even when disconnected from the public
power grid.
Any existing shielding of the communication cable between the unit and the
hy-switch
must be
interrupted on the
hy-switch
side.
For this purpose, use an RJ-45 plug without connection to the shielding on the
hy-switch
side.
The serial number of the unit must be
101191142297
or higher.
Note:
If this is not the case, please contact our KACO Customer Service Centre.
In the house distribution, professional indications of an additional generating systems with
automatic start-up must be attached!

Requirements
The following requirements must be observed for operation:
Do not operate the device with other generators in the same grid, especially in standby mode.
Each phase can be loaded with max. 17 A, whereby the total power in standby power operation should not
exceed 10 kW.
In case of overload in at least one phase, the device switches off the voltage on all three phases after
5 seconds. Reconnection is only possible after manual confirmation of the error on the unit.
In standby power mode, the residual current monitor (RCD) in the device is without function. Therefore,
an external residual current monitor type B 30 mA must be used.
