2.6 Residual voltages in the servo unit and discharge
times
When the EMERGENCY STOP button is pressed or the placement system is switched off, the
electrolytic capacitors quickly discharge to safe residual voltage levels via switched resistors on
the discharge board (00308443-xx).
The voltages can be tapped off at test sockets 001 - 009 on the voltmeter unit in the servo unit. 2
DANGER Automatic placement systems from the SIPLACE family are
powered with 3 x 400 VAC (3 x 208 VAC for the U.S.A. version) ± 5 %, 50/60 Hz main power volt-
age. This means that some parts of the system carry potentially lethal voltages - even when
switched off at the main power switch.
Death, serious injury or considerable damage may result if these automatic placement systems
are handled incorrectly. Always follow the applicable accident prevention and DIN regulations
(particularly EN 60204, part 1).
The guard over the servo unit must ONLY be opened by appropriately qualified and trained per-
sonnel. 2

CAUTION
To avoid losing data, evaluate the following criteria before switching off your automatic placement
system (apart from in emergencies):
– Has the placement system finished transmitting machine, setup and panel data?
– Has the placement system finished processing the PCB?
– Has the placement system completed the run-up phase?
– Has the Windows XP operating system been shut down correctly? 2

WARNING NEVER detach compressed air lines while they are still pressurized. 2
CAUTION 2
When the machine is switched on, do not use the stop valve to interrupt the compressed air supply
for more than 30 minutes. If you need to shut off the pneumatic system for longer in order to carry
out preventive maintenance or servicing work, you must switch the placement system off at the
main switch and disconnect it from the power supply. 2
