4.2.4.2 Transformer 1
The main reason for the transformer T1 is to power the X/Y and star axis, protected by F4. Con-
tactors K2, K3 and K4 illustrate fixed elements of the electrical safety concept. In a fault event, e.g.
open cover, the servos are disconnected from the energy.
The power supply unit provides the following supply voltages:

Primary Transformer T1 4
– 250 VDC for the servo amplifiers of the x and y axes.
– 150 VDC servo amplifiers of the star axis.
– 34 VDC for the inrush current limiter servo
– 52 VDC for the DC/DC converters in the main power unit
– 52 VDC for camera illumination and computer unit DC/DC converter

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).
