2.6 Residual voltages and discharge times
If the EMERGENCY STOP button is pressed or the machine is switched off, the 300 V- interme-
diate circuit voltage for the gantry axes and the 160 V- intermediate circuit voltage for the star and
Z 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 415 V ± 10 %, 50/60 Hz or optionally with
3 x 200 V~ to 3 x 220 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 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 machine finished transmitting machine, setup and panel data?
– Has the machine finished processing the PCB?
– Has the machine completed the run-up phase?

– Cable connection terminals L1, L2, and L3 of the Q1 main power switch
– Cable connection terminals X2, X10, X300, F1 and power pack PS5
– It can take up to 2 seconds until the residual voltage from the EMC filter has been discharged
at the power supply plug.
– Safety cutoff (CSB), capacitor bank, power pack PS4 and testing terminals X303 - X306 re-
main live for 5 minutes after the main switch has been switched off.
DANGER
Danger from residual voltage at the mains plug
After disconnecting the mains plug, a residual voltage of up to 60 µC could still be present
(in line with EN 60204-1). When combining the power supply connections 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.

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).
