Danger to life! The cables between the device and the residual current monitor are not protected
against leakage currents!
The installation of the electrical system must be carried out in such a way that the electrical equipment on
the track is only accessible to qualified personnel.
Check and document the function of the residual current monitoring.
The
hy-switch
must be properly connected to earth. The earthing must also be functional in the event of a
power failure.
When selecting automatic circuit breakers for loads, attention must be paid to the tripping current, as the
maximum short-circuit current is limited to 17 A. The use of circuit breakers only makes sense up to 6.3 A.
The stronger loads are protected by the integrated overload cut-off in the device.
Note:
When switching on large inductive loads (e.g. motors), non-standard flicker can occur.
When switching larger loads, short-term overvoltages of up to 450 V peak can occur. If there are sensitive
consumers in the grid, a suitable overvoltage device is necessary or the loads must be protected with a
suitable grid filter.
A maximum direct current component of 1 A is permissible in standby power operation.
The voltage in the standalone grid (standby power operation) is regulated to 230V
eff
. The frequency can be
selected between 50 and 65 Hz.
Complete shutdown of the system is only possible with the SET button on the device.
Danger to life! Dangerous voltages can build up at connections even in fault condition!
To switch off, the SET button must be pressed for >10 s until the switch-off symbol appears on the display.
The batteries cannot be recharged during standby power operation without PV. Therefore, make sure that
the batteries never get into a deep discharge. The PV yield must compensate for the decrease in energy
from the batteries on a daily basis. Please also consider the self-consumption of the unit.

Installation and use
5.1
Installation in the TN-C-S grid
Basically, a TN-C-S grid is required to use the standby power mode. From the
hy-switch
onwards, PE and N must no
longer be brought together. The
hy-switch
must be properly connected to earth.
The earthing must also be functional in the event of a grid failure, cf
