Machine switched off at the main power switch and disconnected
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 and check for
absence of voltage (see Checking For Absence of Voltage).
► Work on the power supply and the contactor safety breaker (CSB) must only be carried out by
service engineers of ASMPT SMT Solutions or by machine owner service engineers who have
been trained by ASMPT.
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 electrically-
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 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 cutter.
When working in the area of the tape cutter, move the component trolley out of the machine and dis-
connect the machine from the mains supply and the compressed air supply.
► Wait until the operating pressure has dropped to 0 MPa.
► Pull one of the hoses off the Y distributor on the cutter, to vent the pneumatic lines and the cut-
ters (see Venting compressed air at the cutter).
► After completing work to the cutter, you will need to connect the hose again.
► 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.
► Only hold and carry the cutter on the outer left and righthand parts.

1.1.7 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 otherwise. 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 Interrupt the voltage supply.
► Lock out the machine.
ð Attach a lock wherever possible.

[03123101-xx] (replaces:[03121545‑xx])
Alternative: secure the 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
attached when the machine is switched
off!
.
► Attach the lockout attachment(1) to the cir-
cuit 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.
► Attaching warning signs:
If a machine can be locked, it must be.
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.
► Release of stored energy:
Energy stored as compressed air in the compressed air supply or electrical energy stored in elec-
trolytic capacitors must be released by appropriate means.
After switching off the machine, wait until the voltages have discharged and the compressed air
has released, so that work can be performed without any risk.
DANGER
Checking for absence of voltage!
► Before you start working, check the power supply for absence of voltage and observe the waiting
times!
► Testing the lock out:
The lock can be easily tested by pressing the Start button. The machine must not respond.
The following steps must be taken to restore the machine to operation.
► Check the workspace. Authorized employees should remove all of their tools and reinstall all
safety features.
► Notify all affected employees.
► Before removing even one lock or tag, inform all workers in the affected area that the machine is
going to be restarted.
► Remove all locks/tags.
Every authorized employee must remove his own lock and shut it away.
► Switch on the machine. Make sure that authorized staff check the equipment in operation to
ensure that all repairs were performed correctly.
