Control Unit CU320-2
Description
The CU320-2 is the central Control Unit in which the closed-loop and open-loop control
functions are implemented.
Fire hazard due to overheating because of inadequate ventilation clearances
Insufficient ventilation clearances result in overheating with danger to persons as a result of
smoke and fire. This can also result in more downtimes and a reduced service life for the
Control Unit.
• For this reason, it is imperative that you maintain the 80 mm clearances above and
below the Control Unit.
