7.2 Wiring colour description
There is wire colour code to show voltage level of specific single wires. So you can identify voltage
levels at tested parts using wire colors:
Voltage Colour Code Comment
Mains Orange OR All circuits that will show voltage even if
main switch is OFF
Power general Black BK
Neutral line Light blue BU Europe:
According to EN and CE standards
wire color has to be light blue.

7.3 Voltage Overview Block diagrams
7.3.1 Circuit Diagram of Power Supply TX
The diagram above shows a simple overview of the voltage generation with the SMPS.
●
The power pack PS1 converts the mains input AC voltage into 300VDC (for intermediate cir-
cuit voltage man axes) and 160VDC (for intermediate circuit voltage head axis).
●
The 300VDC is run via the backup battery CAP1 to the CSB (Contactor-based Safety
Breaker) the voltage is charged/discharged in a controlled manner via the pre/discharge board
A2 and the energy is backed up by the backup battery CAP1.
●
The power pack PS2 converts the mains input AC voltage into 42VDC.
●
One link of the 42VDC voltage is run via the CSB from where it is then run back to the FDB
and distributed as 42VDC_S (switched).The other link is directly to the discharge head buffer.
●
The power pack PS3 converts the mains input AC voltage into 28VDC.
●
The power pack PS4 converts the mains input AC voltage into 24VDC.
●
This 24VDC voltage is run via the CSB, from where it is then run back to the FDB and distrib-
uted as 24VDC_S (switched).
●
All voltages are protected by the Fuse & Distribution Board (FDB).
