2.7 Residual voltages and discharge times in the machine
If the EMERGENCY STOP button is pressed or the machine is switched off, the 300 VDC inter-
mediate circuit voltage for the gantry axes and the 160 V- intermediate circuit voltage for the star
axes are reduced to harmless residual voltages within a very short time.

DANGER
Dangerous voltage levels!
The machine is supplied with 3 x 360 V~ to 3 x 480 V ± 10 %, 50/60 Hz or optionally with
3 x 200 V~ to 3 x 240 V~ ± 10 %; 50/60 Hz mains voltage. This means that some parts of
the system carry potentially lethal voltages - even when switched off at the main power
switch and with disconnected mains plug.
Incorrect handling of this machine can therefore result in death or severe injury or consid-
erable damage to equipment.
Always follow the applicable accident prevention and DIN regulations (particularly EN
60204, part 1 or IEC 60204, part 1) and the applicable regulations in your own coun-
try.
The covers over the power supply unit may ONLY be opened by appropriately qual-
ified and trained personnel.
DANGER
Lethal voltages in the power supply unit!
The power supply unit has components (capacitors) which can still conduct potentially le-
thal voltages for approx. 5 minutes, even when the machine is switched off and the mains
plug has been disconnected.
Wait at least 5 minutes before you perform work on the power supply unit.
Only ASM Assembly Systems GmbH&Co.KG service engineers or the machine
owner's service engineers, who have been trained by ASM, may perform work on the
power supply and the safety cutoff (CBS).
CAUTION
Data loss!
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?

DANGER
Lethal voltages!
Incorrect handling of the machine can therefore result in death or severe injury or consid-
erable damage to equipment.
The following components still carry potentially lethal voltages in the power supply unit,
even if the main power switch is switched off:
– Mains connection terminals X94
– L1, L2 and L3 of main switch S1
– Service socket X98
– Safety cutoff (CSB) still live for 5 minutes after switching off the main switch.
– The color of all individual wires, which still carry electricity, even if the main power
switch is switched off, is orange.

2.7.4 Compressed air conditions in the machine after switching off at the main
power switch
When the main switch is switched off or the mains supply to the machine fails, the electrically-con-
trolled main valve of the compressed air unit will close (item 1 in fig. 2.8 - 1
, page 104 ). The pres-
sure will drop to 0 MPa (0 bar) within 5 seconds.
