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 system 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
(0bar) within five seconds.

1.1.5 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.
1.1.6 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.
1.1.7 Safety Instructions for Maintenance Tasks
WARNING
Danger of burning
Never use inflammable fluids (e.g. alcohol) for cleaning purposes when working in the
vicinity of a naked flame or fire.
Never spray lubricants or cleaning agents from aerosol cans in the vicinity of a naked
flame or fire.
CAUTION
Consumables
Observe the safety data sheets for consumable materials!
CAUTION
Cleaning and lubrication
Always use ethanol for cleaning – do not use solvents.
Isopropanol – IPA can be used as an alternative.
NEVER use compressed air to clean units inside the placement machine or modules.

CAUTION
Danger of cutting on the IC and FC camera
There is a risk of cutting your fingers along the edges of the mirror.
Wear laboratory gloves as protection and avoid touching the edges.
The laboratory gloves are also required for effective cleaning (fingerprints!).
CAUTION
Only one person must be present at each component preparation station at any
given time.
This is to ensure the safety of the operator and the safety of the second person. Pulling in
the component trolley is a two-handed operation, so only one person can be reliably protec-
ted from the possible risks.
1.1.8 Safety Instructions on Hazardous Materials
CAUTION
Observe the safety data sheets
Observe the applicable safety data sheet, when handling hazardous materials (e. g. Loctite
241, ethanol).
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 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
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.
