2.6 Residual voltages and discharge times
If the EMERGENCY STOP button is pressed or the placement machine is switched off, the 300
V- intermediate circuit voltage for the gantry axes and the 160 V- intermediate circuit voltage for
the star and Z axes will be reduced to harmless residual voltages within a very short time.

DANGER
Dangerous voltage levels!
The placement machine is supplied with 3 x 380 V~ to 3 x 415 V ± 10 %, 50/60 Hz or op-
tionally with
3 x 200 V~ to 3 x 220 V~ ± 10 %; 50/60 Hz mains voltage. Due to the use of energy stor-
age capacitors, parts of the system may conduct hazardous voltages for a certain time
(approx. 5 minutes) even when the main switch has been switched off and the mains plug
has been disconnected.
Incorrect handling of this placement machine can therefore result in death or severe injury
or considerable 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 placement machine has been 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 placement ma-
chine - (apart from in emergencies):
– Has the placement machine finished transmitting setup and panel data?
– Has the placement machine finished processing the PCB?
– Has the placement machine completed the run-up phase?

DANGER
Danger from residual voltage at the mains plug
After disconnecting the mains plug of a placement machine, a residual voltage of up to 60
µC could still be present (in line with EN 60204-1). When combining the power supply con-
nections for multiple placement machines, this could cause a hazard.
DANGER
Lethal voltages!
Incorrect handling of this placement machine can therefore result in death or severe injury
or considerable 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:
– L1, L2 and L3 of main switch Q1
– Cable connection terminals X2, X10, X300, F1 and power pack PS5
– Safety cutoff (CSB), capacitor bank, power pack PS4 and testing terminals X303 -
X306 remain live for 5 minutes after the main switch has been switched off.
– The color of all individual wires, which still carry electricity, even if the main power
switch is switched off, is orange.

power supply

2.6.5 Compressed air conditions after switching off at the main switch
When the main switch is switched off or the mains supply to the placement machine fails, the elec-
trically-controlled main valves of the compressed air unit will close (item 1 in fig. 2.7 - 1
, page 97).
The pressure will drop to 0 MPa (0 bar) within 5 seconds. The components before the electrically-
controlled main valves will remain pressurized.
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 placement machine has been switched
off and the mains plug has been disconnected.
When working on the power supply, switch off the main switch, secure it to prevent
switching on again, disconnect the placement machine from the power network and
wait 5 minutes until the capacitors have discharged.
Test to check that there is no remaining voltage supply. See the procedure described
in the service manual.
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).
