• The Thyrobox VR is a component whose intended usage is as a voltage regulator at the feed

point when feeding renewable energies (e.g. photovoltaic systems) into low voltage networks.

This is what the Thyrobox VR is designed for and it may only be used as such.

• The Thyrobox VR may only be operated in connection with an appropriate upstream and down-

stream mains disconnecting device (e.g. switch, take note of VDE 0105 T1).

• The Thyrobox VR is not functional on its own and must be project planned for its appropriate

usage in order to minimize the residual hazards of the product.

• The Thyrobox VR may at most be operated with the maximum permissible connection values in

accordance with the details on the type plate.

• The Thyrobox VR may only be used for the purpose for which it was intended, as persons may

otherwise be exposed to dangers (e.g. electric shock, burns) and systems also (e. g. overload).

• Appropriate usage includes adhering to the operating instructions and, in particular, also the

carrying out of inspection and maintenance measures. Functional faults, in particular, those which

affect the safety of the device, must be corrected immediately.

RESIDUAL HAZARDS OF THE PRODUCT

• Even during appropriate usage it is possible, in the case of a fault or incorrect operation, that the

following situations occur:

- Regulation at one or more phases drops out,

- Disconnection of the photovoltaic network from the power supply company network

It cannot be ruled out that other loads may show abnormalities in behavior when the Thyrobox VR

is being operated. Please take into consideration the physically induced network feedback.

HAZARD OF ELECTRIC SHOCKS

Even with non-activated thyristors the input and output network of the Thyrobox VR are electrically

interconnected. Even after the separation from the mains, capacitors can still contain dangerously

high levels of energy.

INCORRECT OPERATIONS AND THEIR SEQUENCES

In the case of incorrect operations, higher power, voltages or currents than intended can reach the

Thyrobox VR or the load. This can cause damage to the Thyrobox VR or the load.

In particular, factory-set parameters may not be altered in such a way that the Thyrobox VR is over-

loaded.

TRANSPORT

The Thyrobox VR may only be transported upright in the original packaging (protection against

damage e.g. from the elements, bangs, knocks, contamination).

ASSEMBLY

The Thyrobox VR requires installation in an upright position.
