2.8.5 Hand Guard at the Component Trolley Locations, SIPLACE X-Series
WARNING 2
Component trolleys from the SIPLACE X-series are guaranteed to be safe to use if at least every
other free location is filled with a feeder module or a hand guard (dummy feeder). When a waffle-
pack holder is set up, every other free locations should again be protected again with a hand
guard. In other words, there must be no more than one free location between two adjacent
feeder modules or feeder module and waffle-pack tray holder.

2.9 Residual Voltages and Discharge Times
2.9.1 (Placement) Machine
If the EMERGENCY STOP button is pressed or the placement system is switched off, the 250
VDC link voltage for the gantry axes and the 145 VDC link voltage for the star axes are reduced
to harmless residual voltages in a very short time.
WARNING 2
The placement system is supplied with 3 x 208 V~, 3 x 230 V~, 3 x 380 V~, 3 x 400 V~ or
3 x 415 V~ ± 5 %, 50/60 Hz mains voltage. This means that some parts of the system carry
potentially lethal voltages - even when switched off at the main power switch. Incorrect handling
of the placement system can therefore result in death or severe injury or considerable damage to
equipment.
Always follow the applicable accident prevention and DIN regulations (particularly DIN EN 60
204, part 1).
The guards over the power supply unit and the axis unit must ONLY be opened by appropri-
ately qualified and trained personnel.
