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 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.
Æ Always follow the applicable accident prevention and DIN regulations (particularly DIN EN
60 204, part 1).
Æ The cover over the servo unit must only be opened by qualified and trained personnel.
