2.6.6 Hand guard at the component trolley locations
WARNING 2
All locations must be equipped with feeders in order to guarantee operational reliability.
If there are not enough feeders available, unassigned locations should be fitted with a hand
guard (dummy feeder). When a waffle-pack tray (manual tray) is set up, the remaining locations
should again be protected with a hand guard.

2.7 Residual voltages and discharge times in the
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 VAC, 3 x 230 VAC, 3 x 380 VAC, 3 x 400 VAC or
3 x 415 VAC ± 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.
Æ Always follow the applicable accident prevention and DIN regulations (particularly DIN EN 60
204, part 1).
Æ The guards over the power supply unit and the axis unit must ONLY be opened by appropri-
ately qualified and trained personnel.
