2 Important notes on operational safety
WARNING
The following rules must be observed to ensure that the machines are safe to operate: 2
Å NEVER open a protective hood if you are not totally familiar with the machine sequence and
the way it works. Do not open the protective hoods during operation unless you are prompted
to do so in this manual or in the station software dialog.
Å Only appropriately trained and qualified personnel must set the key switch to set-up mode (‘I’).
During operation, do not turn the key switch to the ‘I’ position (set-up mode) unless you are
prompted to do so in this manual or in the station software dialog. 2
Å NEVER move your head or arms into the gantry travel range while the station is switched on.
Å Do not make any modifications unless you are totally aware of the effects they will have on the
overall operation of the line.
Å The stations must only be set up, changed over and maintained by appropriately trained
personnel.
Å Only use Siemens AG original spare parts and authorized accessories. The use of other parts
can affect safety and may invalidate the liability for any resulting damage.
Å The operational safety of SMD placement machines can only be guaranteed if the machines
are used in the intended manner and the instructions of the user manual / service manual are
followed.

Å The machine keys for opening the doors over control and servo units and the keys for key
switches should be kept so that they are only accessible to qualified personnel.
Å ALWAYS call in a Siemens AG service engineer if work is required on the machine and there
are no appropriately trained personnel within your company. Siemens AG shall not be held
liable for any claims arising from incorrect work, damage or consequential damage.
Å The machine operators must only carry out activities for which they have received adequate
training and with which they are fully familiar.
Å Always follow the safety regulations specific to your country.
Å Protective devices must not be modified. In particular, circuit-breakers must not be bypassed
and protective devices must not be removed.
Å If significant hazards are identified while the machine is in use, the machine operator is
required to immediately notify the manufacturer in writing so that the manufacturer can initiate
the action needed to reduce the potential hazard.
