2.8 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.
WARNING 2
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~,
3x400V~ or 3x415V~ ± 5%, 50/60Hz mains voltage. This means that some parts of the sys-
tem carry potentially lethal voltages - even when switched off at the main power switch. Incorrect
handling of the machine can therefore result in death or severe injury or considerable 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 qualified and
trained personnel.
