CHAPTER 1 SAFETY FEATURES
PRINTER SAFETY FEATURES
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 or residual danger
may exist
• Safety interlocks ensure that potentially hazardous machine operations
can only be performed when the machine is 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.
Mains Supply Where incoming hazardous supply voltages are present, protection is afforded
by controlling access to the enclosures that house the supply. The enclosures
require tools to gain access to the inside and must only be opened by suitably
qualified personnel.
The mains isolator switch disconnects the facility 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 danger-
ous voltage (115V-230V a.c 50-60Hz) terminations are present within.
Safety Notices Safety notices in the form of PROHIBITION, WARNING, CAUTION and MAN-
DATORY labels are placed on the printing printer and notices are posted
throughout the associated documentation to alert the operator/maintainer to
possible hazards which may cause physical injury or equipment damage.
The following label illustrated below, may be fitted to the printer, this signifies
that the user should refer to the relevant section of the Technical Reference
Manual before attempting to carry out work on the equipment.
