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.

DANGER
Dangerous voltage levels!
The machine 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. Parts of the system therefore carry lethally
hazardous voltages - even when the main switch is switched off.
Incorrect handling of this machine can therefore result in death or severe injury or consid-
erable damage to equipment.
Always follow the applicable accident prevention and DIN regulations (particularly EN
60204, part 1 or IEC 60204, part 1) and the applicable regulations in your own coun-
try.
The covers over the power supply unit may ONLY be opened by appropriately quali-
fied and trained personnel.

CAUTION
Data loss!
To avoid losing data, assess the following criteria before switching off your machine (apart
from in emergencies):
– Has the machine finished transmitting machine, setup and panel data?
– Has the machine finished processing the PCB?
– Has the machine completed the run-up phase?
