Lockout attachment [03121545-xx]
► 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-ener-
gized 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:
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.
Attaching the lockout attachment [03121545-xx]
Example: 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.

DANGER - Checking the power supply for absence of voltage
► 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 all 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 to administer the Lock Out / Tag Out Procedure.

DANGER
Checking for absence of voltage!
► Before you start working, check the power supply for absence of voltage and observe the
waiting times!
CAUTION
High weight
The heavy weight of the module could cause injuries if the module is not handled correctly.
► Do not lift or carry the module alone.
► During removal, remember that the SIPLACE JTF-ML (25.7 kg), is heavy. You might need
to enlist the help of a second person.

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.

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.
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 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.
