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.
► Lock out the machine.
ð Attach a lock wherever possible:
Fig.8: Attaching a padlock to the main power switch
Secure Main Switch
► Secure the main switch with a padlock.
► Alternative: 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 to warn employees that the
machine is de-energized for servicing. The tag or label must be securely fastened, it must be
placed in a position visible to all 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
electrolytic 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 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.
Testing
Service personnel may test circuits by energizing them briefly without suspending the Lock Out /
Tag Out Procedure. This may only be done when no other work is being performed by any other
person on the equipment being tested.
It is extremely important that all remote START switches are tagged with the "Do Not Operate" tag
to prevent inadvertent operation of the equipment during these periods.
Responsibilities
●
It shall be the responsibility of the maintenance and service personnel to make sure this pro-
cedure is adhered to.
●
It shall be the responsibility of the maintenance and service personnel's immediate supervisor
to instruct their personnel on this procedure.
●
It shall be the responsibility of the Safety Officer to administer the Lock Out / Tag Out Proced-
ure.

1.3 Other Instructions
1.3.1 Environmentally-Friendly Disposal of Materials and Components
SIPLACE products are manufactured using only materials and parts that can be easily separated
and disposed of in an environmentally-friendly way.
NOTICE
Observe the applicable regulations
The company operating the system has sole responsibility for the proper, environmentally-
friendly disposal of machines, working materials, consumables and wear parts.
► Please observe your national statutory provisions for waste disposal and environ-
mental protection.
1.3.2 Use of Original SIPLACE Accessories and Spare Parts
Only use original spare parts and authorized accessories. The use of other parts will affect safety
and will invalidate the liability for any consequential damage.
1.3.3 Information About This Service Manual
WARNING
Additional qualifications required
The service work described in this manual may only be performed by specially trained ser-
vice technicians, with appropriate qualifications and expertise.
If you should have any questions during the service work, please contact the SIPLACE customer
hotline directly or send an e-mail to hotline.siplace@asmpt.com.
1.3.4 ESD Guidelines
1.3.4.1 Definition of ESD
Almost all of the modules in use today are equipped with highly integrated MOS blocks and com-
ponents. The manufacturing techniques used mean that these electronic components are ex-
tremely sensitive to overvoltage and thus to electrostatic discharge.
Fig.9: ESD label
The abbreviation for such modules is "ESD"(Electrostatic Sensitive
Device). This is used internationally, although the German abbreviation
"EGB" may also be seen. The following symbol on cabinet rating plates,
racks or packaging indicates that components which are sensitive to elec-
trostatic discharge have been used and thus that the modules concerned
are also touch-sensitive.
ESDs can be destroyed by voltages and electrostatic charges that are far below the level that can
be perceived by humans. Such voltages occur if a person touches a component or module
without earthing themselves. Components that are exposed to such overvoltage do not generally
appear to be defective immediately - incorrect behavior starts after the component or module has
been in operation for some time.
1.3.4.2 Important Measures to Protect Against Static Charging
► Most plastics can easily become charged and must therefore be kept away from at-risk com-
ponents.
► Always ensure that people, the workplace and packaging are safely earthed when handling
electrostatic sensitive components.
