Maintaining, installing or removing assemblies
► End all placement operations on the machine.
► Shut down the Windows operating system correctly, otherwise problems may occur when
restarting or data may be lost.
► Switch the machine off at the main switch.
► Disconnect the machine from the main power supply.
► Switch off the machine and attach warning signs to indicate that service work is in progress.

1.1.4 Safety instructions for the power supply (with SMPS)
NOTICE
Validity
This section applies to the following machine types with SMPS (Switched Mode Power Supply):
► SIPLACE SX1/SX2 edition V3 from serial no. Rxxxx
► SIPLACE SX1/SX2 edition V2 from serial no. Nxxxx
Residual voltages and discharge times in the machine
If the emergency stop button is pressed or the machine is switched off, the 300V~ link voltage for the
gantry axes and the 160V~ link voltage for the star axes are reduced to harmless residual voltages in
a very short time.
CAUTION
Residual voltages
► After switching off the machine, wait at least 10 seconds before you switch it back on again, so
that stored residual voltages can dissipate.
► Please note that longer waiting periods apply when working on the power supply.
DANGER
Dangerous voltages!
The machine is supplied with 3 x 380 V~ to 3 x 415 V ± 10 %, 50/60 Hz or optional with 3 x 200 V~ to
3 x 220 V~ ± 10 %; 50/60 Hz mains voltage and contains energy-storing components. This means
that some parts of the system carry potentially lethal voltages - even when it is switched off at the
main power switch and the power plug is unplugged.
Death, serious bodily injury or considerable damage may result if these machines are handled incor-
rectly.
► Always follow the applicable accident prevention and DIN regulations (particularly EN60204,
part 1 or IEC 60204, part 1) and the applicable regulations in your own country.
► The covers of the power supply unit may only be opened by appropriately qualified and trained
personnel.
► Please observe the safety instructions in the user manual for all work!
► Before you start working on the power supply, check it for absence of voltage and observe the
indicated waiting times!
CAUTION
Loss of data!
To avoid losing data, assess that the following criteria have been met before switching off your
machine (apart from in emergencies):
► The machine has finished transmitting machine, setup and panel data.
► The machine has finished processing the PCB.
► The machine has 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 incorrectly.
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 (if present)
► The contactor safety breaker (CBS) still carries voltage for five minutes after switching off
at the main switch.
Make sure that you wait another five minutes before performing tasks on the CSB.
► The color of all individual wires which still carry potentially lethal voltages even if the main power
switch is switched off is orange.
