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.
