If the Thyrobox VR is only to be temporarily shut down then the following steps are necessary for

decommissioning.

The decommissioning of the Thyrobox VR refers to ﬁg. 12 Block diagram Thyrobox VR and Cable

Distribution Cabinet.

13.1 SEQUENCE OF DECOMMISSIONING

ATTENTION

Danger of short circuit

F30 in the cable distribution cabinet and F1 in the Thyrobox VR must not be closed simultaneously,

otherwise there is a short circuit.

ATTENTION

Danger of short circuit when not adhering to the sequence of the following steps.

ATTENTION

Danger of network fall out (PV side) through tripping fuses F30 when not adhering to the switching

sequence.

For decommissioning the Thyrobox VR the following steps are required:

1. Open fuse load switch F1 (125 A) Thyrobox VR

2. Close F30 cable distribution cabinet

3. Open F10 and F20 cable distribution cabinet

Status of the Thyrobox:

The Thyrobox VR is now free of voltage and bypassed, which means voltage regulation is no

longer taking place, utility (EVU) and PV side are connected directly with one another via F30

(cable distribution cabinet).

With these steps the decommissioning for the purpose of temporary (short term) shutdown is

completed. If the Thyrobox VR is to be shut down for a longer period then further measures are

required (see also Chapter Storage and Chapter Disassembly).
