3 Setting Up and Connecting the PS40W
3.1 Front Panel
The front panel of the PS40W holds the connectors for delivering the supply voltage
to the following devices as well as two green LED lights indicating the negative and
the positive output voltage of 7 volts, respectively.
The color of the plugs indicates the polarity.
Blue 4 mm blue connector Negative supply voltage
Black 4 mm black connector Power ground
Red 4 mm red connector Positive supply voltages
The front panel LED’s light up if the negative and the positive voltages are stable.
A flashing light can be caused by short-circuits or over-temperature. If the LED’s
are dark, the voltage is reduced to lower values.
Warning: Do not mismatch the polarity of the power supply.
A false connection may cause permanent damages.
Note: If by any cause the supply voltages are reduced, the recorded signals
could be deformed.
3.2
Rear Panel
The rear panel of the device holds the main switch and the main power supply
connector. Please use only the provided power supply cords. Do not switch on the device
when manipulating the cables delivering the supply voltages to the device of interest.
