Figure 5 on page 18 shows the location of the elec-
trical connectors on the scan head.
Power Supply
There should be no more than ±5 V potential differ-
ence between the grounds of the power source and
the control computer. Both the power source and the
control computer should be grounded. Usually the
ground of the control computer is already connected
to the mains’s grounding wire (PE) via the mains
cable. Therefore the ground of the power source - i.e.
the GND connector on the output side of your power
supply - should also be connected to the mains's
grounding wire (PE; see “cable 1” in figure 10). The
cable connecting the GND connector with the PC
ground should be as short as possible, as long
connections can also produce excessive potential
differences.
The scan head provides a

Requirements
For power, the scan head requires a balanced source
of ±(15+1.5) V with a maximum current of 3 A per
pole. The residual ripple of the power source should
not exceed 10 mV
pp
(power sources with larger
residual ripple may be applicable – after reconsulting
SCANLAB – for applications which only require
reduced quality).
Only use a power supply with soft start.
