3.2 GENERAL
DEK printing machines incorporate safety features that provide a safe operating environment for
the operator and the machine.
All safety circuits have been designed to meet the safety requirements as outlined in the machines’
CE Declaration of Conformity. The circuits check for welded contacts before resetting. Additional
safety is achieved by duplication of the power contactors to provide redundancy.
