WARNING
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. 2
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 guard over the power supply unit must ONLY be opened by appropriately qualified and
trained personnel.

2.10.1 Machine switched off at the main switch, but still connected
WARNING
The following components still carry potentially lethal voltages even if the main power switch is
switched off:
– Mains connection terminals in the transformer unit L1, L2 and L3 of main switch.
– Service socket X102 with F1 automatic circuit breaker switched on.
– The color of all individual wires, which still carry potentially lethal voltages even if the main
power switch is switched off, is brown.
