2.2Power Supply Connector
Figure 3: Orientation of the Positronic
P-47 Power Supply Connector
The DC input voltage to the power supply unit and the V1 ... V4 output voltages
from the power supply unit to the backplane are connected via a 47-pin Positronic male power supply connector.
For the pinouts of the Positronic P-47
power supply connector please refer to

2.3Installation
Thanks to its plug-in compatibility this P-type power supply unit allows for an easy installation,
by which the power supply unit’s male Positronic 47-pin power connector is inserted into the
backplane’s mating female connector without the need of any intermediate adaptation.
Warning!
If this type of power supply is removed for any reason from an operating system, do not reinstall immediately. Wait 1 to 2 minutes before
reinstalling. Failure to comply with this may result in an Output Failure
indication on the power supply. This is due to an internal protection
feature of the power supply which requires time to cool down before
the power supply is put back into operation.

Warning!
Adequate thermal cooling of the power supply must be ensured.
Therefore do not obstruct or hinder cooling air circulation or heat conduction within the power supply or surrounding equipment.
Failure to comply with this warning may result in damage to your
equipment.
