CAUTION
Loss of data!
To avoid losing data, assess the following criteria before switching off your machine (apart
from in emergencies):
► Has the machine finished transmitting machine, setup and panel data.
► Has the machine finished processing the PCB.
► Has the machine completed the run-up phase.
Machine switched off at the main switch, but still connected
DANGER
Risk of death by voltages!
Death, serious injury or considerable damage may result if these machines are handled
incorrectly.
The following components still carry potentially lethal voltages on the power supply even if
the main power switch is switched off:
► Main power supply cable connection terminals
► L1, L2, and L3 of the main switch S1
► Service socket X98 (if present)
► The contactor safety breaker (CBS) still carries voltage for five minutes after switching
off at the main switch.
► The color of all individual wires which still carry potentially lethal voltages even if the
main power switch is switched off is orange.

DANGER
Hazardous voltages in the power supply unit!
The power supply unit houses components (capacitors) that can carry hazardous voltages
for about five minutes after the machine has been switched off and the power plug has
been unplugged.
► Wait at least five minutes before your start working on the power supply unit.
► Work on the power supply and the contactor safety breaker (CSB) must only be car-
ried out by service engineers of ASM Assembly Systems GmbH & Co. KG or by
machine owner service engineers who have been trained by ASM.

Compressed air conditions in the machine after switching off at the main switch
When the machine is switched off at the main power switch or if the power supply fails, the electric-
ally-controlled main valve of the compressed air unit closes. The pressure will drop to 0 MPa
(0bar) within five seconds.
1.1.4 Safety instructions for the compressed air supply
CAUTION
Risk of injury from compressed air!
Risk of injury when disconnecting the compressed air lines.
► Never disconnect compressed air lines while they are still pressurized.
CAUTION
Prolonged interruptions to the compressed air supply can cause damage.
When the machine is switched on, do not use the shutoff valve to interrupt the compressed
air supply for more than 30 minutes.
► If you need to shut off the compressed air system for longer in order to carry out your
work, you must switch the machine off at the main switch and disconnect it from the
power supply.
1.1.5 Safety instructions for work on the cutting device
WARNING
Risk of injury when working near the tape cutter.
When working in the area of the tape cutter, move the component trolley out of the machine
and disconnect the machine from the mains supply and the compressed air supply.
► Wait until the operating pressure has dropped to 0 MPa.
► Always secure the machine against unauthorized reactivation.
► Do not reach into the tape cutter.
CAUTION
Risk of injury when performing service work on the tape cutter.
Never support the tape cutter on your body, e.g., on your knees or thighs. Do not place
your feet under the tape cutter.
► Wear appropriately thick protective gloves.
► When removing/fitting the tape cutter, hold it only outside on the left and right.
1.1.6 Safety instructions for the gantry
CAUTION
Moving the gantry can damage the placement head.
When moving the gantry, observe the following:
► NEVER move the gantry by pushing with your hands against the placement head.
► NEVER push the gantry while the Z axis is lowered.

1.2 Preparatory work...
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 other-
wise. If you do not need to switch off the machine, this will be clearly stated.
The procedure, when followed correctly, eliminates the possibility of an employee being injured.
NOTICE
Additional safety measures
This procedure represents the minimum lock out and 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 officer, the
safety committee and the health department.
Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is
to be followed.
► Notify all affected employees.
► Switch off the machine and all additional devices. Carry out all normal stopping procedures:
ð Press the STOP button.
ð Shut down the station computer.
ð Switch off the machine using the main switch.
► Isolate the machine from all its energy sources:
ð Shut off the compressed air supply.
ð Shut off the main power supply.
► Lock out the machine.
ð Attach a lock wherever possible.
Fig.2: Attaching a padlock to the main power switch
Secure main switch
► Secure the main switch with a padlock.
► Alternatively, you can attach warning signs:
Any machine that can be locked must be locked.
However, there are situations where energy isolating devices cannot accommodate locks. In
these cases, the energy isolating devices must be tagged appropriately to warn employees
that the machine is currently de-energized for service purposes. The tag or label must be
fastened securely in a position visible from all sides and it may only be removed by the person
who attached it.
