Energy state of the machine after switching off at the main power switch
DANGER
Hazardous voltages in the power supply unit!
The power supply unit houses components (capacitors) that can carry hazardous voltages
for about 5minutes after the machine has been switched off and the power plug has been
unplugged.
► Wait at least five minutes before your start working on the power supply unit.
► Work on the power supply and the contactor safety breaker (CSB) must only be car-
ried out by service engineers of ASM Assembly Systems GmbH & Co. KG or by
machine owner service engineers who have been trained by ASM.
CAUTION
Loss of data!
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?
Machine switched off at the main switch, but still connected
DANGER
Risk of death by voltages!
Death, serious injury or considerable damage may result if these machines are handled in-
correctly.
The following components still carry potentially lethal voltages on the power supply even if
the main power switch is switched off:
► Main power supply cable connection terminals
► L1, L2, and L3 of the main switch S1
► Service socket X98
► The contactor safety breaker (CBS) still carries voltage for five minutes after switching
off at the main switch.
► The color of all individual wires which still carry potentially lethal voltages even if the
main power switch is switched off is orange.

Compressed air conditions in the machine after switching off at the main switch
When the system is switched off at the main power switch or if the power supply fails, the electric-
ally-controlled main valve of the compressed air unit closes. The pressure will drop to 0 MPa
(0bar) within five seconds.

1.1.5 Safety instructions for the compressed air supply
CAUTION
Risk of injury from compressed air!
Risk of injury when disconnecting the compressed air lines.
► NEVER disconnect compressed air lines while they are still pressurized.
CAUTION
Prolonged interruptions to the compressed air supply can cause damage.
When the machine is switched on, do not use the shutoff valve to interrupt the compressed
air supply for more than 30 minutes.
► If you need to shut off the compressed air system for longer in order to carry out your
work, you must switch the machine off at the main switch and disconnect it from the
power supply.
1.1.6 Safety Instructions for Work on the Cutting Device
WARNING
Risk of injury when working near the tape cutter.
When working in the area of the tape cutter, move the component trolley out of the machine
and disconnect the machine from the mains supply and the compressed air supply.
► Wait until the operating pressure has dropped to 0 MPa.
► Always secure the machine against unauthorized reactivation.
► Do not reach into the tape cutter.
CAUTION
Risk of injury when performing service work on the tape cutter.
Never support the tape cutter on your body, e.g., on your knees or thighs. Do not place
your feet under the tape cutter.
► Wear appropriately thick protective gloves.
► When removing/fitting the tape cutter, hold it only outside on the left and right.
1.1.7 Safety Instructions for Maintenance Tasks
WARNING
Danger of burning
► Never use inflammable fluids (e.g. alcohol) for cleaning purposes when working in the
vicinity of a naked flame or fire.
► Never spray lubricants or cleaning agents from aerosol cans in the vicinity of a naked
flame or fire.
CAUTION
Consumables
Observe the safety data sheets for consumable materials!
CAUTION
Cleaning and lubrication
► Always use ethanol for cleaning – do not use solvents.
► Isopropanol – IPA can be used as an alternative.
► NEVER use compressed air to clean units inside the placement machine or modules.
