DANGER
Dangerous voltage levels!
The machine is supplied with 3 x 200 V~, up to 3 x 415 V~ 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 consid
-
erable 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 coun

try.
The covers of the power supply unit may ONLY be opened by appropriately qualified
personnel.
CAUTION
Data loss!
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?
