Alpha XMP-8D for PWE-3 and PWE-6 Installation Instructions
The Alpha XMP-8D transformer module enables any XM2/XM3 power supply to provide localized 120VAC uninterruptible
power, up to 250W, for devices such as Small Cell radios. The XMP-8D is also available with an optional selectable
auxiliary power output (5Vdc or 12Vdc) up to 11W, intended to power an auxiliary device, such as a MetroE NID. The
XMP-8D is powered from the 60/90V output of the XM2/XM3.

Equipment powered by XMP-8D should be located outside of the Alpha PWE enclosure using
an Alpha-approved mounting bracket. Placing active powered equipment, e.g. Small Cell
Radios inside the PWE cabinet may exceed the thermal design, resulting in premature failure
of the Alpha Power Supply and batteries, in addition to the powered equipment itself. Alpha will
not be liable for any damage to Alpha or 3rd party equipment caused by excess heat from non-
approved configuration.
CAUTION!
(for XMP-8D-AUX only)
(for XMP-8D-AUX only)
The PWE Fan Kit (
P/N: 745-101-20
) is required for XMP installations where the XM3 total load
(including the XMP) exceeds 15A.
CAUTION!
Do not operate the 5VDC/12VDC Auxiliary select switch while the device is powered on.
