2.2.5 Guards on the component table locations
DANGER 2
All locations must be equipped with feeder modules in order to guarantee operational safety. If
there are not enough feeder modules available, a guard (dummy feeder) must be used in place
of the modules.

2.3 Residual voltages in the servo unit and discharge
times
If the emergency stop mushroom-head push-button is pressed or the placement system is
switched off, the 200 V link voltage for the gantry axes and 100 V link voltage for the star axes are
discharged to harmless residual voltages in a very short time. 2
The voltages can be tapped at test sockets X1 - X4 on the voltage measuring unit in the servo unit.2
DANGER 2
The placement system is supplied with 3 x 204 V AC (US version), 3 x 230 V AC, 3 x 380 V AC,
3 x 400 V AC or 3 x 415 V AC ± 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 switch. Incorrect
handling of the placement system can therefore result in death or severe injury or considerable
damage to equipment.
Å Always follow the applicable accident prevention and DIN regulations (particularly DIN EN
60 204, part 1).
Å The cover over the servo unit must only be opened by qualified and trained personnel.
