CAUTION 2
To avoid losing data, assess the following criteria before switching off your machine (apart from in
emergencies):
– Has the machine finished transmitting machine, setup and panel data?
– Has the machine finished processing the PCB?
– Has the machine completed the run-up phase?
2.8 Disabling the compressed air supply and discharg-
ing the pressure
The compressed air working pressure of the machine is set to 0.51 ± 0.01 MPa (5.1 ± 0.1 bar).
The position of the compressed air unit is indicated by Fig. 2.8 - 1
. The compressed air supply to
the machine can be interrupted using the shutoff valve (item 1 in Fig. 2.8 - 1
).
→ Remove the four screws from the cover.
→ Lift off the cover (see Fig. 2.8 - 1
).
→ Turn the lever on the shutoff valve (item 1 in Fig. 2.8 - 1
) from the vertical to the horizontal
position.
→ Watch the working pressure gauge (item 4 in Fig. 2.8 - 1
). When the machine is switched on,
the pressure discharges to 0 MPa (0 bar) within 1 minute.
CAUTION
When the machine is switched on, do not use the stop valve to interrupt the compressed air sup-
ply 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 machine 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. 2

the main power switch

WARNING
The machine is supplied with 3 x 200 VAC, 3 x 208 VAC, 3 x 230 VAC, 3 x 380 VAC, 3 x 400 VAC
or 3x415VAC ± 5%, 50/60Hz main power voltage. This means that some parts of the system
carry potentially lethal voltages - even when switched off at the main power switch. Incorrect han-
dling of the machine can therefore result in death or severe injury or considerable damage to
equipment. 2
→ Always follow the applicable accident prevention and DIN regulations (particularly DIN
EN 60 204, part 1).
→ The guard over the power supply unit must ONLY be opened by appropriately qualified and
trained personnel.
2.9.1 Machine switched off at the main switch, but still connected
WARNING
The following components still carry potentially lethal voltages even if the main power switch is
switched off:
– Infeed terminals X100 (item 2 in Fig. 2.9 - 1
, page 78)
– Discharge reactor Z2 (item 4 in Fig. 2.9 - 1
)
– Fuses FU, FV, FW and FBU (item 1 in Fig. 2.9 - 1
)
– Line filter Z1 (item 5 in Fig. 2.9 - 1
)
– Service socket BU1 (item 3 in Fig. 2.9 - 1
)
– Cable connection terminals 1, 3, and 5 of the S1 main power switch (item 6 in Fig. 2.9 - 1
)
– The color of all individual wires, which still carry potentially lethal voltages even if the main
power switch is switched off, is brown.
– Axis unit
