The main switch disconnects the three phases L1, L2 and L3 from the power supply.
DANGER
The following components still carry potentially lethal voltages even if the main switch is switched
off:
– cable connection terminals 1, 3, and 5 of S1 main switch
– Z1 main power filter
– BU1 service socket
– F1 automatic circuit breaker for the service socket
– The color of all individual wires, which still carry potentially lethal voltages even if the main
switch is switched off is brown.
– The uninterruptible power supply and the station computer may also still carry potentially lethal
voltages when the main switch is switched off.
Å Incorrect handling of the placement system can therefore result in death or severe injury or
considerable damage to equipment.
Å Always follow the applicable accident prevention and DIN regulations (particularly DIN EN
60 204, part 1) or the regulations specific to your country.
Å The safety doors to the power supply unit must only be opened by appropriately qualified and
trained personnel.

After switching on at the main switch, start the station computer and machine controller. All supply
voltages, apart from the link voltages for the gantry axes (200 V) and star axes (100 V), are then
available.

After switching on at the main switch, you will be prompted to press the Start button in order to
start the placement system for placement jobs. The same prompt appears if you open the protec-
tive covers or press the emergency stop mushroom-head push- button.

The service socket is contained in the power supply unit and is protected by the safety doors. It
can only be used if the placement system is connected to the main power supply via a 5-wire con-
nection (L1, L2, L3, MP and PE). If a 4-wire connection is used, e.g. without N, the socket cannot
be used.
Always follow the safety instructions concerning potentially lethal voltages - even when the place-
ment system is switched off.

The emergency stop mushroom-head push-button is a red, mushroom-shaped button. It latches
in the ON position when pressed. When you press the emergency stop mushroom-head push-but-
ton, the switching contact of the safety circuit opens and the protective contactor combination
(PCC) trips. The link voltage (200 V) for the gantry axes is switched off, whereas the link voltage
(100 V) for the star axes is reduced to 6 VDC. The servo amplifiers for the dp and z axes are still
supplied with 30 VDC. The signalling contact of the emergency stop mushroom-head push-but-
tons closes and the message "Emergency stop pressed" appears on screen. The following mo-
dules:
– PCB conveyor
– PCB clamping
– width adjustment
– PCB stopper and
– used tape cutter
are deactivated.
PLEASE NOTE Placement is interrupted and can either be continued or cancelled once the
machine is restored to working order.
