2.7 Residual voltages and discharge times in the
machine
If the EMERGENCY STOP button is pressed or the machine is switched off, the 200 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 VAC, 3 x 208 VAC, 3 x 230 VAC, 3 x 380 VAC,
3 x 400 VAC or 3 x 415 VAC ± 5 %, 50/60 Hz main power 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 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 DIN EN 60
204, part 1).
→ The guards over the power supply unit and the axis unit must ONLY be opened by appropri-
ately qualified and trained personnel.

CAUTION 2
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?
