2.9 Energy state of the machine after switching off at
the main power switch
2
WARNING
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 3x415VAC ± 5%, 50/60Hz 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 han-
dling 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 DIN
EN 60 204, part 1).
→ The guard over the power supply unit must ONLY be opened by appropriately qualified and
trained personnel.
2.9.1 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:
– Infeed terminals X100 (item 2 in Fig. 2.9 - 1
, page 78)
– Discharge reactor Z2 (item 4 in Fig. 2.9 - 1
)
– Fuses FU, FV, FW and FBU (item 1 in Fig. 2.9 - 1
)
– Line filter Z1 (item 5 in Fig. 2.9 - 1
)
– Service socket BU1 (item 3 in Fig. 2.9 - 1
)
– Cable connection terminals 1, 3, and 5 of the S1 main power switch (item 6 in Fig. 2.9 - 1
)
– The color of all individual wires, which still carry potentially lethal voltages even if the main
power switch is switched off, is brown.
– Axis unit

The following table specifies the voltages of modules when the machine is switched off at the main
switch, but still connected to the mains supply.

2.9.2 Machine switched off at the main power switch and disconnected
The machine is unpowered, apart from slight residual voltages in the power supply unit.
2.9.3 Compressed air conditions in the machine after switching off at the main
power switch
When the system is switched off at the main power switch (item 1 in Fig. 2.9 - 1) or if the power
supply fails, the electrically-controlled main valve Y1 of the compressed air unit closes (item 1 in
Fig. 2.8 - 1
). The pressure will drop to 0 MPa (0 bar) within 5 seconds.
