DANGER
Automatic placement systems from the SIPLACE family are powered with 3 x 400 V ± 10 %, 50/60 Hz mains
voltage.
This means that parts of the system carry potentially fatal voltages - even when switched off at the main
switch.
Death, serious injury or considerable damage may result if these placement systems are handled incorrectly.
Always follow the applicable accident prevention and VDE regulations (particularly VDE 0113).
The guards over the control and servo units must ONLY be opened by appropriately qualified and trained per-
sonnel.

1.5.1 Placement system switched off at the main switch, but still con-
nected to the mains
The following table specifies the voltages of assemblies when the automatic placement system is switched off
at the main switch, but still connected to the mains supply.
1.5.2 Placement system switched off at the main switch and discon-
nected from the mains
The automatic placement system is unpowered, apart from slight residual voltages in the servo unit.
1.5.3 Compressed air conditions in the automatic placement system
after switching off at the main switch
When the system is switched off at the main switch (item 1 in Fig. 1.5.1) or if the power supply fails, the elec-
trically-controlled main valve Y1 of the compressed air unit closes (Fig. 1.4.1, page 1 - 23
). The pressure will
drop to 0 bar within 5 seconds.
