Inverter
The subject matter of the invention is an inverter ( 1 ), comprising a casing ( 8 ) as well as at least one casing cover ( 2 ), said casing cover ( 2 ) being mechanically engaged with a safety plug ( 10 ), said safety plug ( 10 ) being in electrical connection with at least the one load-current circuit located on the DC side, the inverter being switched off or disconnected at least from the DC-side load-current circuit after removal of the safety plug from the casing ( 8 ).
1. An inverter, comprising a casing with first and second casing chambers covered by first and second casing covers, respectively, said first casing cover being mechanically engaged with a safety plug, said safety plug being in electrical connection with a load-current circuit located on a DC side of the inverter, wherein pulling the safety plug from the casing causes a switch to disconnect the inverter at least from the load-current circuit and wherein the first casing cover covers fastening elements of the second casing cover in a closed state.
2. The inverter as set forth in claim 1 , wherein the safety plug further connects the inverter to a load-current circuit on an AC side of the inverter.
3. The inverter as set forth in claim 1 , wherein the first casing cover comprises at least one eyelet through which the safety plug extends.
4. The inverter as set forth in claim 3 , wherein the safety plug comprises a plug head and a plug body, said plug body extending through the at least one eyelet of the first casing cover.
5. The inverter as set forth in claim 1 , wherein the first casing chamber comprises electrical connecting elements including at least one of the following: a plug, a socket, or an electronic component.
6. The inverter as set forth in claim 1 , wherein the second casing chamber accommodates electronic components of the inverter.
7. The inverter as set forth in claim 1 , wherein the first casing chamber comprises a communication unit with a display.
8. An inverter comprising a casing with a first casing cover covering a first casing chamber, the first casing cover being mechanically locked by a safety plug when the safety plug is in an inserted position, and the first casing cover being removable when the safety plug is in a pulled out position, wherein the safety plug is configured to toggle a switch when the safety plug is pulled out of the casing, thereby disconnecting the inverter from a DC-side-load-current circuit, wherein the safety plug is configured to further disconnect an AC-side-load-current circuit when pulled out of the casing.
9. An inverter comprising a casing with a first casing cover covering a first casing chamber and a second casing chamber with a second casing cover, the first casing cover being mechanically locked by a safety plug when the safety plug is in an inserted position, and the first casing cover being removable when the safety plug is in a pulled out position, wherein the safety plug is configured to toggle a switch when the safety plug is pulled out of the casing, thereby disconnecting the inverter from a DC-side-load-current circuit, wherein the first casing cover is arranged such that the second casing cover can only be removed after removal of the first casing cover.
