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 uninterruptable power supply and the station computer may also still carry potentially
lethal voltages when the main switch is switched off.
– Incorrect handling of the placement system can therefore result in death or severe injury or
considerable damage to equipment.
NOTE
The color of all individual wires, which still carry potentially lethal voltages even if the main switch
is switched off, is brown.
Å Always follow the applicable accident prevention and DIN regulations (especially DIN EN 60
204, part 1) and the specific regulations of your country.
Å The safety doors to the power supply unit must be opened by appropriately qualified and
trained personnel only.

Switching on of the main switch, will 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.
