Placement system switched off at the main power switch and disconnected
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.

DANGER
Hazardous voltages in the power supply unit!
The power supply unit houses components (capacitors) that can carry hazardous voltages for
about 5 minutes after the machine has been switched off and the power plug has been un-
plugged.
► 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 ser-
vice engineers who have been trained by ASM.
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.
CAUTION
Observe the safety data sheets
Observe the applicable safety data sheet, when handling hazardous materials (e. g. Loctite
241, ethanol).

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.
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 compressed air supply.
⇨ 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).
NOTICE
Additional safety measures
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 officer, the safety committee
and the health department.

Example 1: Securing the machine with a lockout at-
tachment
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 attached when
the machine is switched off!
► Attach the lockout attachment (1) to the circuit
breaker.
► Secure the circuit breaker with a padlock.
