2.5.1 Main switch switched off - machine system connected to the main power
supply
The following table shows the voltages of the individual modules when the main switch is switched
off, but the placement system is still connected to the main power supply. 2
DANGER 2
The following components still carry potentially lethal voltages even if the main switch is switched
off: 2
– cable connection terminals 1, 3, and 5 of S1 main switch
– Z1 main power filter
– BU1 service socket
– F1 automatic circuit breaker for the service socket
– The color of all individual wires, which still carry potentially lethal voltages even if the main
switch is switched off is brown.

2.5.2 Main switch switched off - machine disconnected from the power supply
The placement system is de-energized, apart from slight residual voltages in the servo unit. 2

2.5.3 Compressed air conditions in the machine after switching off at the main
switch
When the placement system is switched off at the main switch (item 1 in Figure 2.5 - 1) or the
power supply to the placement system fails, the electrically-controlled main valve Y1 shuts off the
compressed air unit (item 3 in Figure 2.5 - 1
). The pressure drops to 0 bar within 5 seconds. 2
