CAUTION 2
When the machine is switched on, do not use the stop valve to interrupt the compressed air supply
for more than 30 minutes. If you need to shut off the pneumatic system for longer in order to carry
out preventive maintenance or servicing work, you must switch the placement system off at the

The compressed air working pressure is set to 0.52 MPa (5.2 bar). It may fluctuate between 0.5
MPa (5.0 bar) and 0.53 MPa (5.3 bar). The position of the compressed air unit is indicated by
item 5 in Fig. 2.7 - 1
. The compressed air supply to the machine can be interrupted using the
shutoff valve (item 1 in Fig. 2.7 - 1
).
– You must remove the cover plate to use the shut-off valve.
– Turn the lever on the shut-off valve (item 1 in Fig. 2.7 - 1
) from the vertical to the horizontal
position.
– Watch the working pressure gauge (item 2 in Fig. 2.7 - 1
) and the pressure gauge for the com-
pressed air supply to the stopper (item 4 in Fig. 2.7 - 1
). When the automatic placement system
is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.

2.8 Energy state of the machine after switching off at
the main power switch
WARNING 2
Automatic placement systems from the SIPLACE family are powered with 3 x 400 V or 3 x
208 VAC (U.S.A. version) ± 5 %, 50/60 Hz mains voltage. This means that parts of the system
carry potentially fatal voltages - even when switched off at the main switch. Death, serious injury
or considerable damage may result if these automatic placement systems are handled incor-
rectly. Always follow the applicable accident prevention and DIN regulations (particularly
EN 60204, part 1). The guards over the control and servo units must ONLY be opened by appro-
priately qualified and trained personnel. 2
