WARNING 2
All locations must be equipped with feeders in order to guarantee operational reliability. If there
are not enough feeders available, a guard ("dummy feeder") must be fitted in place of the feeder.2

2.6 Residual voltages and discharge times in the
machine
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.
WARNING 2
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 voltage. 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
