CAUTION The following conditions must be fulfilled before switching off the placement
system (apart from in emergencies) in order to avoid the loss of data:
– the placement system must have stopped transmitting machine, set-up and cluster data.
– the placement system must have stopped processing the PCBs.
– the placement system must have completed the start-up phase.
– the Windows NT operating system must have been shut down correctly.

The compressed air operating pressure is permanently set to 5.3 bar. The position of the com-
pressed air unit is indicated by item 4 in the diagram. The compressed air supply to the placement
system may be interrupted using the shut-off valve (item 1 in the diagram).
Å Open the safety doors.
Å Turn the lever of the shut-off valve (item 1 in the diagram) from the vertical to the horizontal
position.
Å Check the operating pressure gauge and the pressure gauge for the compressed air supply to
the stopper (items 2 and 3 the diagram). When the placement system is switched on, the pres-
sure drops to 0 bar within 1 minute.
CAUTION 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 maintenance or servicing work, you must switch the placement system
off at the main switch and disconnect it from the power supply.

WARNING
NEVER detach compressed air lines while they are still pressurized. Risk of injury.
1. Shut-off valve lever in the CLOSED position
2. Operating pressure gauge
3. Pressure gauge for the component table operating pressure
4. Position of the compressed air unit on the placement system

DANGER
The placement system is supplied with 3 x 204 V (US version) or 3 x 400 V or 3 x 460 ± 10 %,
50/60 Hz main power voltage. This means that some parts of the system carry potentially lethal
voltages - even when switched off at the main switch. Incorrect handling of the placement system
can therefore result in death or severe injury or considerable damage to equipment.
Å Always follow the applicable accident prevention and DIN regulations (particularly DIN 60 204,
part 1).
Å The cover over the servo unit must only be opened by qualified and trained personnel.
