WARNING 2
→ Never reach into the gap between the component trolley and the machine base (item 1 in Fig.
2.5 - 2
, page 52).
→ Never connect the supply cable (item 3 in Fig. 2.5 - 2
, page 52) for the component trolley to
the socket (item 2 in Fig. 2.5 - 2
, page 52) on the machine and then operate the component
trolley outside the machine via the compressed air control unit .
→ Always connect up the supply cable (item 3 in Fig. 2.5 - 2
, page 52) for the CO trolley to the
machine socket (item 2 in Fig. 2.5 - 2
, page 52) before you lower the table bed. To do this,
ensure that the supply cable is always on the side of the machine socket.
2.5.3 Safety instructions for lowering the component table bed
WARNING DANGER OF CRUSHING 2
→ When lowering the component table bed, never reach into the gap between the feeders and
the used tape channel.
2.5.4 Safety instructions for moving the component trolley
WARNING
To prevent accidents, ALWAYS follow the rules listed below when you move the component trol-
ley.
→ Always hold the handles with both hands when you move the component trolley.
→ Always lower the component table before moving the component trolley.
→ Remember that a component trolley with the full complement of feeder modules can tip over
sideways or forward on gradients of 20° or more.
→ Make sure that the surface on which the trolley is moved has a significantly smaller gradient.
→ Be careful not to collide with obstacles. The trolley could tip forward if it is traveling fast
enough.

2.5.5 Safety instructions for processing capacitors based on powdered metal
There is a risk associated with processing capacitors based on powdered metal (e.g. tantalum).
The risk is that
– an exothermic reaction, i.e. a sudden build-up of heat, may occur, if these components are
damaged. If the ambient conditions are unfavorable, and depending on the capacitance, this
buildup of heat can cause damage.
– this effect can occur when these components are cut.
Please contact your suppliers to clarify whether the components that you handle are affected.
In extremely rare cases, this risk can occur in the tape cutter of SIPLACE machines, with the
remote possibility of causing a smoldering fire in the waste tape.
The ambient conditions are unfavorable if:
(1) The components remain on the tape while the set tape cycle is checked (since the operator
can cycle the feeder onward without removing components during this check).
(2) The components remain on the tape, e.g. due to a tear in the cover foil.
(3) The components remain on the tape, and the components or tape do not conform to the spec-
ification, thus increasing the pickup error rate.
2
Please follow the instructions given below to minimize the risk when placing capacitors based on
powdered metal.
(1) If the component tape is cycled onward manually, the operator must remove any components
remaining in the tape pocket.
(2) If the cover foil tears, the operator must remove any components remaining on the tape.
To ensure that tantalum capacitors do not cause the tape material to burn when it is cut as a result
of pick-up errors, the user interface has been extended to include the "Remove component from
tape in the event of a pick-up error" option. This option must be enabled in SIPLACE Pro. On the
placement machine, the component that was not picked up is paced forward again until it is ready
for removal from the component tape. The track is deactivated and the operator is sent an error
message to remind him to pick up the tantalum component from the tape.
PLEASE NOTE: 2
The manual extraction by the operator of tantalum capacitors that have not been picked up is
described in Section 3.9.6 on page 121.

2.5.6 Safety instructions for the hand guard on the input/output belt
DANGER OF CRUSHING! 2
The guard must always be set to the height of the circuit board to be processed. The gap between
the guard and the safety bar should be kept as small as possible. The guard is mounted on the
input and output belts of the PCB conveyor.
→ Never reach through the gap into the inside of the machine. There is a danger of crushing
from the lifting table.
→ Adjust the height of the guard at the slots so that the circuit board to be processed can be
carried through.
