4.2.4.4 Voltages in the Power Supply Unit after switching on
When the main switch is switched on, the following voltages are generated and may or may not
be switched (enabled, not enabled) through to the modules:

Voltages for the service socket 4
NOTE:
The service socket can only be used if the placement system is connected to the main power sup-
ply with a 5-conductor cable (L1, L2, L3, N, PE).

4.2.4.5 DC/DC Converter in Main Power Supply
Two DC/DC converter U20 and U30 generate the +24 VDC and +5 VDC, which are used overall
in the electrical system, are located in the main power supply module.
DC/DC converter U20:
1.+24 VDC converted from 52 VDC is split into 4 path
– path 1: power for servo enable
– path 2: SSK relay K6
– path 3: for inrush current limiter servo
– path 4: mainly used: general use of 24V all over the machine
2.+24 VDC converted from 52 VDC is split into 2 path:
– ventilator for the axis unit
– PCB transport control board
DC/DC converter U30:
5 VDC logic power, which is mainly used in the overall machine

4.2.5 Power Supply Computer Unit
When the main switch is on, the DC/DC converter in the computer unit is supplied with 52 VDC
by the main power supply unit. The following voltages are then generated in the control unit:
4
+ 3.3 VDC / 6A to supply the CPU of Machine Controller and CPU of Station Computer. 4
+ 5 VDC / 6A to supply the digital electronic circuits. 4
± 12 VDC to supply the digital electronic circuits. 4
± 15 VDC (not used, LED off) 4
