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.
1.1.5 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.

Secure circuit breaker
The lockout attachment can prevent the
machine from being switched on inadvertently.
► Switch off the machine.
► Set the circuit breaker to OFF.
CAUTION!
The lockout attachment may only be at-
tached when the machine is switched
off!
.
► Attach the lockout attachment(1) to the
circuit breaker.
► Secure the circuit breaker with a padlock.
NOTICE
Lockout attachment in the service box of your machine
On machines that are delivered from June 2016, the lockout attachment [03123101‑xx] is
located in the service box.

► 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.
