DANGER
Dangerous voltages at the safety contactors after switching off the machine
After switching off the machine at the main switch, Pos. 4 - fig.
2.8 - 2 various compo-
nents (e.g. capacitors) at the power supply unit can carry dangerous voltages for approx.
5 minutes. The contactor unit is safely protected behind a cover.
Never open the cover of the safety contractors Pos. 4 - fig. 2.8 - 2.

2.8.1.2 Machine switched off at the main power switch and disconnected
The machine is unpowered, apart from slight residual voltages in the power supply unit.
2.8.2 Residual voltages and discharge times after pressing the EMERGENCY STOP
button
If the EMERGENCY STOP button is pressed or the machine is switched off, the 300 VDC link volt-
age for the gantry axes and the 160 VDC link voltage for the star axes are reduced to harmless
residual voltages in a very short time.
