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.

2.2 SAFETY NOTICES
Safety notices in the form of PROHIBITION, WARNING, CAUTION and MANDATORY labels are
placed on the printing machine 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 label illustrated below, fitted to the printer, signifies that the user should refer to the relevant
section of the Technical Reference Manual before attempting to carry out work on the equipment.
2.2.1 Prohibition Notices
Prohibition notices draw the attention of operators/maintainers to prohibiting behaviour likely to
cause a risk to health or safety. The following table displays the prohibition labels affixed to
machine and displayed in the machine documentation.

PROHIBITION
STRONG MAGNETIC FIELD. A STRONG MAGNETIC FIELD EXISTS IN THE
VICINITY OF THE LINEAR MOTORS THAT MAY ACT UPON FERROUS OB-
JECTS WHOSE MOVEMENTS COULD LEAD TO PERSONAL INJURY AND/
OR DAMAGE TO THE MACHINE.
PROHIBITION
STRONG MAGNETIC FIELD. A STRONG MAGNETIC FIELD EXISTS IN THE
VICINITY OF THE LINEAR MOTORS THAT REPRESENT A SERIOUS HAZ-
ARD TO PEOPLE FITTED WITH METALLIC IMPLANTS.
PROHIBITION
ELECTROMAGNETIC FIELD. AN ELECTROMAGNETIC FIELD EXISTS
WITHIN THE MACHINE FROM THE LINEAR MOTORS. THESE MAY
PRESENT A HAZARD TO PEOPLE FITTED WITH AN IMPLANTED CARDIAC
DEVICE. THE MOTOR MANUFACTURER RECOMMENDS A SAFE DISTANCE
OF AT LEAST 400MM.
PROHIBITION
MACHINE COVERS. IN ORDER TO PROTECT PERSONNEL AND TO PRE-
VENT DAMAGE TO THE MACHINE, COVERS ARE FITTED TO THE MACHINE
FRAME. THESE PANELS MUST ONLY BE REMOVED BY SUITABLY QUALI-
FIED PERSONNEL.

BOARD CLAMPS. EXTREME CARE MUST BE EXERCISED WHEN WORKING
IN THE TOOLING AREA OF THE MACHINE TO AVOID INJURY. THE FOILS
ON THE FRONT AND REAR BOARD CLAMPS ARE VERY SHARP.
WARNING
FLAMMABLE. FLAMMABLE SUBSTANCES ARE PRESENT. KEEP AWAY
FROM HEAT, SOURCES OF IGNITION AND STATIC DISCHARGES. USE IN A
WELL VENTILATED AREA.
WARNING
LETHAL VOLTAGE. DANGEROUS VOLTAGES EXIST IN THIS EQUIPMENT.
ENSURE ALL ELECTRONIC COVERS AND MAIN MACHINE COVERS ARE
FITTED BEFORE OPERATING THIS EQUIPMENT.
WARNING
HOT SURFACES. THE SURFACE OF THIS COMPONENT OR SURROUNDING
AREA MAY BECOME HOT DURING PROLONGED OPERATION. CARE TO BE
TAKEN WHEN WORKING IN THE VICINITY OF THIS COMPONENT.

WARNING
STRONG MAGNET FIELD. A STRONG MAGNETIC FIELD EXISTS IN THE VI-
CINITY OF THE LINEAR MOTORS. THIS MAY PRESENT A HAZARD TO PER-
SONNEL OR EQUIPMENT.
WARNING
COMPRESSED AIR. COMPRESSED AIR SHOULD NEVER IMPINGE UPON
THE BODY. PORTS, PIPES, ETC MUST NEVER BE BLOCKED BY HAND. BE-
FORE CONNECTING OR DISCONNECTING ANY PNEUMATIC COPMPON-
ENTS, ENSURE THE COMPRESSED AIR SUPPLY HAS BEEN DISSIPATED
AND DISCONNECTED FROM THE MACHINE.
WARNING
E STOP CIRCUIT. THE E STOP CIRCUIT FITTED TO THE MACHINE ONLY
ISOLATES THE DC SUPPLIES TO THE MOTORS. LETHAL VOLTAGES ARE
STILL PRESENT WITHIN THE MACHINE AFTER THE E STOP HAS BEEN AC-
TIVATED.
WARNING
HARMFUL SUBSTANCES. CLEANING WIPES AND CLEANING SOLUTIONS
MAY CONTAIN SUBSTANCES HAZARDOUS TO HEALTH. WHEN USING
CLEANING WIPES AND CLEANING SOLUTIONS THE MANUFACTURERS’
