Caution!
!
The printed circuit boards of digital equipment contain CMOS circuits. These shall not
be withdrawn or inserted under live conditions! The modules must be so handled that
any possibility of damage due to static electrical charges is excluded. During any
necessary handling of individual modules or printed circuit boards the recommenda-
tions relating to the handling of electro-statically endangered components (EEC) must
be observed. In installed conditions, the modules are in no danger.
