2.7 Residual voltages and discharge times in the machine
If the EMERGENCY STOP button is pressed or the machine is switched off, the 260 VDC link volt-
age for the gantry axes and the 150 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 200 V~, 3 x 208 V~, 3 x 220 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 this machine can therefore result in death or severe injury or con-
siderable 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
country.
The covers over the power supply unit may ONLY be opened by appropriately qual-
ified and trained personnel.
