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.
