► Switch the machine off at the main switch.
► Disconnect the machine from the main power supply.
► Switch off the machine and attach warnings signs to indicate that service work is in progress.
1.1.4 Residual voltages and discharge times in the machine
1.1.4.1 Energy state of the machine after the EMERGENCY STOP button is pressed
If the EMERGENCY STOP button is pressed, the voltages are reduced to harmless residual
voltages in a very short time.
WARNING
S
The machine is supplied with 1/N/PE ~ 240, 50/60 Hz mains voltage. This means that
some parts of the system carry potentially lethal voltages -
main power switch. Incorrect handling of the machine can therefore result in death or
severe injury or considerable damage to equipment.
► Always follow the applicable accident prevention and safety regulations (particularly
DIN EN 60204, part 1 or IEC 60204, part 1) and the safety regulations in your own
country.
► The covers over the power supply unit may ONLY be opened by appropriately

WARNING

some parts of the system carry potentially lethal voltages -
main power switch. Incorrect handling of the machine can therefore result in death or

The following components still carry potentially lethal voltages even if the main power switch is
switched off:
– Mains connection terminals of the main power switch.
To avoid losing data, assess the following criteria before switching off the machine (apart from in
emergencies):
– Has the machine finished transmitting machine and recipe data?
– Has the machine finished processing the PCB?
– Has the machine software completed the shot-down phase?
1.1.4.3 Machine switched off at the main power switch and disconnected
The machine is unpowered, apart from slight residual voltages in the power supply unit.

1.1.5 Safety Instructions for the Gantry
When moving the gantry, observe the following:
1.1.6 Safety Instructions on Hazardous Materials
CAUTION
Observe the applicable safety data sheet, when handling hazardous materials (e. g.
1.1.7 Classification of the Optical Systems
1.1.7.1 Classification of the Camera Systems
The camera illumination systems are fitted with light LEDs. These are assigned to risk
group 1 according to IEC 62741:2006.
1.2 Lock out and tag out procedure
1.2.1 Purpose and Scope
Before performing any preventive maintenance work, conversion work or service work, a procedure
of locking and tagging must be followed and warning signs must be attached if not stated
otherwise. If it is not necessary to switch off the machine, it is explicitly mentioned.
The procedure, when followed correctly, eliminates the possibility of an employee being injured.
NOTICE
These procedures represent the minimum lock/tag out requirements for the machine
during preventive maintenance work and service work. Any additional safeguards
needed to complete work safely can be specified by facilities supervision, the safety
1.2.2 Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is
to be followed.
► Notify affected employees.

► Switch off the machine and all additional devices. Carry out all normal stopping procedures:
● Press the STOP button.
● Shut down the station computer.
● Switch the machine off at the main switch.
► Isolate the machine from all its energy sources:
● Shut off the main power supply.
► Lock out the machine.
● Attach a lock wherever possible (e.g. to the main power switch or the motor contactor).
If a machine can be locked out, it must be. However, there are situations where energy
isolating devices cannot accommodate locks. In these cases, the energy isolating
devices must be tagged to warn employees that the machine is de-energized for
servicing. The tag must be securely fastened, it must be placed in a position visible to all
► Release stored energy:
Stored energy in the electrical energy in electrolytic capacitors must be released by appropriate
means.
● After switching off the machine, wait the specified discharge time (see sections 1.1.4Residual
voltages and discharge times in the machine and 1.2Lock out and tag out procedure), before
the machine can be operated again without risk.
► Verify the lock out:
Testing the lock out can be done simply pressing the start button.
► The following steps must be taken to restore the machine to operation:
● Check the area. Authorized employees should remove all of their tools and reinstall all guards.
● Notify all affected employees.
● Before removing even one lock or tag, inform all workers in the area that the machine is going
to be restarted.
● Remove locks/tags
● Each authorized employee must remove his or her own lock. Each authorized employee will
have his or her own lock.
● Turn the machine on. Authorized workers should observe the equipment in operation to ensure
repairs were done correctly.

1.2.3 Testing
Service personnel may test the circuits by activating them briefly without canceling the locking
method. This may be done only when no other work is being performed by any other person on the
equipment being tested.
It is extremely important that all remote start switches be tagged with the Do Not Operate tag to
prevent inadvertent operation of the equipment during these periods.
