Energy state of the machine after switching off at the main power switch
 DANGER!
Hazardous voltages in the power supply unit!
The power supply unit houses components (capacitors) that can carry haz-
ardous voltages for about 5 minutes after the machine has been switched off
and the power plug has been unplugged.
Wait at least 5 minutes before your start working on the power supply unit.
Work on the power supply and the contactor safety breaker (CSB) must only
be carried out by service engineers of ASM Assembly Systems GmbH & Co.
KG or by machine owner service engineers who have been trained by ASM.
.
 CAUTION!
Loss of data!
To avoid losing data, assess the following criteria before switching off your
automatic placement system (apart from in emergencies):
Has the placement system finished transmitting machine, setup and panel
data?
Has the placement system finished processing the PCB?
Has the placement system completed the run-up phase?
.
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 electrically-controlled main valve of the compressed air unit closes. The
pressure will drop to 0 MPa (0 bar) within 5 seconds.
Placement system switched off at the main switch, but still connected
 DANGER!
Risk of death by voltages!
Incorrect handling of the placement system can result in death or severe in-
jury or considerable damage to equipment.
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
Contactor safety breaker (CBS) still carries voltage for 5 minutes after switch-
ing 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.

Safety Instructions for Maintenance Tasks
 WARNING!
Danger of burning
Never use inflammable fluids (e.g. alcohol) for cleaning purposes when work-
ing 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!
Ethanol
Always wear safety goggles and gloves when using concentrated ethanol to
clean modules.
If ethanol should accidentally get into your eyes, rinse your eyes immediately
with water.
.
 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!
Consumables
Observe the safety data sheets for consumable materials!
.
 CAUTION!
SIPLACE cleaning tissue
Harmful: may cause lung damage if swallowed.
Do not inhale vapor / aerosol.
Avoid contact with the skin. If swallowed, do not induce vomiting. See med-
ical attention immediately and show the packaging or label.
Wear latex gloves while using the cleaning tissue.
.
 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 per-
son. Pulling in the component trolley is a two-handed operation, so only one
person can be reliably protected from the possible risks.

Safety Instructions for Work on the Cutting Device
 WARNING!
Risk of injury when working near the 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.

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).
.
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 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!
Additional safety measures
These procedures represent the minimum lock/tag out requirements for the
machine during preventive maintenance work and service work. Any addi-
tional safeguards needed to complete work safely can be specified by facilit-
ies supervision, the safety officer, the safety committee and the health de-
partment.
.
Description
Whenever it becomes necessary to isolate, control and release energy, the follow-
ing procedure is to be followed.
u Notify affected employees.
u Switch off the machine and all additional devices. Carry out all normal stop-
ping procedures:
ð Press the STOP button.
ð Shut down the station computer.
ð Switch the machine off at the main switch.
u Isolate the machine from all its energy sources:
ð Shut off the compressed air supply.
ð Shut off the main power supply.
u Lock out the machine.
ð Attach a lock wherever possible (e.g. to the main power switch or the mo-
tor contactor).
