German datasheet notation?

[rea5245]

Hi. A quick question for German speakers. I have a German datasheet for a Nixie tube. There's a notation on two of the pins that says "ic".

I assume that means "no connection". But what are the German words it's abbreviating?

Thanks.

Apparently it is an english abbreviation. The answer is here:

In german datasheets the abbreviation is iV.

The English abbreviation "IC" for "internal connection-do not use" (per RCA tube manuals) is very common on vacuum-tube data sheets.
The pin through the "button" base is a convenient place to support one of the internal bits of the tube, and that pin on the socket should not be used as a connection lug. 
Unused pins where the socket pin may be used are abbreviated "NC-no connection".
What is the literal meaning of the abbreviation "iV" in German?

interne Verbindung -> internal connection

 I love German datasheets. The senisbly refer to voltage with a U not a V.
I like thef mittelschrift used in the old ones too.
Ahh, the smell of burning dust and hot bakelite... Hummmm. Hilversummmmm.

Also, they know how to spell their own language, even if they use "U" instead of V.
