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 ti me to cool down before
the power supply is put back into operation.
