3) Even if the main power switch is in the "OFF" position, servo drivers,
frequency converter and switching power supply may still be live
4) Burn hazards arising from the surface temperature of servo driver and
frequency converter heatsink.
5) The surface temperature of the newly cut workpiece is high, which may
cause burns.
