The TURBOTRONIK NT 151/361 is supplied in a table
top housing.
It may also be built into a rack. In this case sufficient ven-
tilation must be ensured and the ambient temperature
must not exceed 40°C during operation.
The four holes in the front panel are used for installing
the unit in a 19" rack.
Warning
If the TURBOTRONIK is built into a rack the
mains plug is not within easy reach. There-
fore install a separation between the TUR-
BOTRONIK and the mains when you build
it into a rack.
Plug in the mains cable at (4/7).
Warning
Do not operate the TURBOTRONIK with
the standard mains lead in chemically
aggressive surroundings. If you operate the
TURBOTRONIK in chemically aggressive
surroundings replace the mains lead by a
resistant one.
