2.4.4 Safety instructions for opening the protective covers
To prevent any risk of injury when the protective covers on automatic placement machines are
opened, the owner must instruct his operators to use the protective covers exactly as specified in
the following description.
RISK OF CRUSHING HANDS IF THE PROTECTIVE COVERS
ARE OPENED OR CLOSED INCORRECTLY
When opening of closing the protective covers, always place both hands
in these recessed grips (see item (1) in Fig. 2.4 - 2
). This “two-handed operation”
will prevent any risk of injuring your hands. You will also avoid tilting the protective covers during
opening or closing, which would place an excessive load on the guides. 2

2.4.5 Securing the placement machine to prevent it slipping
In areas with an earthquake risk, it is essential to secure the placement machine to prevent it
slipping.
Two holes for M8 bolts are provided in the machine feet for this purpose.
Æ Use the bolts to fix the placement machine to the floor as shown in the diagram below.

2.4.6 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 buildup of heat, may occur, if these components are dam-
aged. 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
specification, thus increasing the pickup error rate.
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.
WARNING
To avoid the risk, it is essential to use only feeders that have been approved for placing such com-
ponents, namely:
for model C/D item no.: 00141118-01
for model E item no.: 00141117-01 2
