► 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 fas
-
tened, 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:
Stored energy in the compressed air supply or electrical energy in electrolytic capacitors must be
released by appropriate means.
⇨ After switching off the machine, wait until the voltages and the compressed air have discharged,
so that work can be performed without any risk.
► 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 working area. 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 locks/tags
► Every authorized employee must remove his own lock and shut it away.
► Turn the machine on. Make sure that authorized staff check the equipment in operation to ensure
that 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 be tagged with the "Do Not Operate" tag to pre
-
vent inadvertent operation of the equipment during these periods.
Responsibilities
▪ It shall be the responsibility of the maintenance and service personnel to make sure this procedure
is adhered to.
▪ It shall be the responsibility of the maintenance and service personnel's immediate supervisor to in
-
struct his personnel on this procedure.
▪ It shall be the responsibility of the Safety Officer with assistance from the Safety Committee, Health
Service Department, and the various managers and vice-presidents to administer the Lock Out / Tag
Out Procedure.

1.3.1
1.3.1 Environmentally-Friendly Disposal of Materials and Components
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.
1.3.2
1.3.2 Use of Original SIPLACE Accessories and Spare Parts
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.

Important Measures to Protect Against Static Charging
► Most plastics can easily become charged and must therefore be kept away from at-risk components.
► Always ensure that people, the workplace and packaging are safely earthed when handling electro
-
static sensitive components.
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 environmental
protection.
WARNING
Additional qualifications required
The service work described in this manual may only be performed by specially trained service
technicians, with appropriate qualifications and expertise.
Almost all of the modules in use today are equipped with highly integrated MOS blocks and compo
-
nents. The manufacturing techniques used mean that these electronic components are extremely sen
-
sitive to overvoltage and thus to electrostatic discharge.
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 compo
-
nents which are sensitive to electrostatic discharge have been used and thus that the
modules concerned are also touch-sensitive.
ESDs can be destroyed by voltages and power levels 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 them
-
selves. Components that are exposed to such overvoltages do not generally appear to be defective im
-
mediately - incorrect behavior starts after the component or module has been in operation for some
time.

1.3.4.3 Handling ESD Modules
Handling ESD Modules
Do not touch electronic modules unless it is absolutely essential to do so in order to carry out other work.
If it is necessary, make sure that you do not touch the pins or printed conductors when you pick up flat
modules.
Do not touch components unless
▪ You are constantly earthed by an ESD wrist strap or
▪ You are wearing ESD shoes or ESD shoe earthing strips on an ESD floor.
Always discharge yourself before you touch an electronic module. To do this, simply touch a conductive
and earthed object immediately before you touch the module (such as unpainted parts of a switch cab
-
inet, a water pipe, etc.).
Do not allow modules with chargeable and highly insulating materials to touch one another, e.g. plastic
films, insulating table surfaces or items of clothing made from synthetic fibers.
Always place the modules on a conductive surface (table with an ESD coating, conductive ESD foam,
ESD bag or container).
Do not bring modules near visual display units, monitors or televisions. Keep them at least 10 cm away
from the screen.
1.3.4.4
1.3.4.4 Measurements and Modifications to ESD Modules
Measurements and Modifications to ESD Modules
Measurements of the assemblies may only be taken if
▪ The measuring device has been grounded (e.g. via protective conductor) or
▪ The measuring head of the potential-free measuring device has been briefly discharged before
measurement (e.g. touching blank metal control unit housing).
► Always use an earthed soldering iron if you carry out any soldering work.
1.3.4.5
1.3.4.5 Dispatching ESD Modules
Dispatching ESD Modules
► Always store modules and components in conductive packaging (e.g. metallized plastic bags or met
-
al sleeves) and dispatch them in conductive packaging.
► If the packaging is not conductive, place the modules in a conductive envelope before packaging.
Use conductive foam rubber, ESD bags, domestic aluminum foil or paper, for example. NEVER use
plastic bags or film.
► If the module has integral batteries, ensure that the conductive packaging does not touch or short-
circuit the battery terminals and, if necessary, first cover the terminals with insulating tape or mate
-
rial.
