– 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).

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 88).
The pressure will drop to 0 MPa (0 bar) within 5 seconds. The components before the electrically-
controlled main valves will remain pressurized.
