your plug, proceed as follows:
1 . The wire which is coloured blue must be
connected to the terminal in the plug
which is marked with the letter N or
coloured black .
2 . The wire which is coloured brown must be
connected to the terminal which is marked
with the letter L or coloured red .
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harm-
ful to the environment .

installation into a rack (482 mm / 19") . However,
it can also be used as tabletop unit, if required .
For rack installation, a height of 1 RS (rack space)
= 44 .45 mm is required .
