2.7.1 Placement system switched off at the main power switch, but still connected
The following table specifies the voltages of assemblies when the automatic placement system is
switched off at the main switch, but still connected to the mains supply. 2
WARNING 2
The following components still carry potentially lethal voltages even if the main power switch is
switched off: 2
– cable connection terminals 1, 3, and 5 of the S1 main power switch
– main power filter Z1
– 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
power switch is switched off, is brown.

2.7.2 Placement system switched off at the main power switch and disconnected
The automatic placement system is unpowered, apart from slight residual voltages in the servo
unit. 2
2.7.3 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. 2.7 - 1) or if the power
supply fails, the electrically-controlled main valve Y1 of the compressed air unit closes (item 3 in
Fig. 2.7 - 1
, page ). The pressure will drop to 0 MPa (0 bar) within 5 seconds. 2
