2.1 OVERVIEW
TECHNICAL REFERENCE MANUAL DEK TQ 04/2021 9
2 SAFETY FEATURES
2.1 OVERVIEW
The printer incorporates various safety features that provide a safe operating environment for the
operators/maintainers using:
●
Safety labels to inform the user of areas where danger may exist
●
Safety circuits to ensure that the machine can only be operated when in a safe condition
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.
2.1.1 Mains Supply
Where incoming supply voltages are present, protection is afforded by controlling access to the en-
closures that house the supply. The enclosures require tools to gain access to the inside and must
only be opened by suitably qualified engineers.
The mains isolator switch removes mains supply to the power supply enclosure. Mains supply still
exists in the printer, up to the mains isolator switch.
Hazard warning labels are placed on the outside of enclosures where dangerous voltage
(100V-240V) terminations are present within.

section of the Technical Reference Manual before attempting to carry out work on the equipment.
