1.1Introduction
The Alpha UPE-M series of metered CA TV power supply enclosures are a secure, ruggedly designed,
water-resistant enclosure with separate raceways for utility power and CA TV wiring. The enclosure
is designed to meet code and safety standards specified by EUSERC and the NEC.
The utility meter compartment is isolated from the CA TV compartment. Utility access doors contain
padlock hasps with separate sealing screws. A small hole is provided in each screw and hasp to
accommodate a lead wire seal. The CA TV doors have flush-mounted key locks installed.
The utility meter compartment contains a hinged, lockable, Lexan window for meter reading. The
utility meter can be accessed by lifting the hinged door .
The standard UPE-M enclosure has a fault current interrupt rating of 10,000A. A 65,000A version is
also available.
There are three basic models in the UPE-M series, available in both 10KAIR and 65KAIR
configurations. The UPE-M3 and UPE-M6 models are designed for the XM2-615, XM2-915, and
XM2-1350 power supplies with 36V inverters. The UPE-M8 model is designed for the XM2-1350,
XM2-615, and XM2-922 power supplies with 48V inverters.

2.0Site Preparation
2.1Site Considerations
The following points must be considered when choosing a location for the enclosure installation:
•Plan the site so the enclosure will receive good air flow. If possible, in areas of extreme heat,
position the enclosure so it is shaded from the afternoon sun.
•In areas of prevailing winds, locate the enclosure so the back of the cabinet faces the wind
instead of the sides. This will reduce the buildup of sand or snow against the enclosure’s air
vents.
•In areas of potential flooding, locate the installation above the 100-year flood plain .
•Place the enclosure where it will be free of obstructions and allows easy access to the doors
for service or equipment access. For ventilation and maintenance, allow a minimum of 36
inches in the front and rear of the enclosure.
•Place the enclosure well away from ground level sources of forced water, such as underground
sprinkler systems or direct roadway splash.
•The concrete pad drawing provided in this manual contains the required mounting details,
including electrical service and cable plant entrances.
•For ease of installation, lightweight polymer, high density polyethylene mounting supports
(Alpha PS Series) are available from Alpha T echnologies for UPE-M series enclosures.
•A vapor barrier material (such as 30 lb. felt, neoprene pond liner, or heavy grade tar paper)
should extend at least six inches in all directions around the perimeter of the enclosure. It can
be trimmed closer to the enclosure after installation.
•Install batteries only after the unit is on site and secured to the pad. Transporting the unit with
installed batteries may cause a short circuit, fire, explosion, and/or damage to the battery
pack, enclosure or installed equipment. Damage caused by improperly shipping or transporting
a unit with installed batteries is not covered under warranty.
•The batteries used in this application may vary slightly depending upon optional configurations,
battery types, or customer requirements. The batteries are typically valve-regulated gelledelectrolyte, such as the AlphaCell. If a battery is found damaged, refer to the battery
manufacturer's documentation regarding the safe handling of the battery .

2.4Enclosure Grounding
Alpha Technologies recommends using the grounding method illustrated below. The grounding
method for a particular site is depends on soil type, available space, local codes, National Electric
Code (NEC) requirements, and other site-specific characteristics.
Alpha T echnologies recommends a minimum of five ohms ground resistance between the enclosure
and ground rods, but resistance shall not exceed 25 ohms, in accordance with IEEE 1 100-1999
(Powering and Grounding Electronic Equipment).
Alpha T echnologies assumes no responsibility or liability for failure of the inst aller to comply with
the requirements of all applicable local and national codes. Where allowed, exothermic welding
may be used as an alternative to Burndy clamps and connectors.

3.0Installation
3.1Enclosure Installation
Tools Needed:
•Ratchet set with 6” extension
•Vapor Barrier
•Utility Knife
Procedure:
A 25-year continuous vapor barrier must be used between the enclosure and pad to prevent moisture
ingress and possible corrosion caused by metal to concrete contact. The vapor barrier material
(such as 30 lb. felt, neoprene pond liner, or heavy grade tar p aper) should initially extend at least
six inches in all directions around the perimeter of the enclosure.
1. Unwrap the enclosure and inspect the contents. If items are missing or damaged, contact
Alpha T echnologies and the shipper immediately .
2. Place the vapor barrier material on the pad.
3. Unbolt the enclosure from the shipping pallet.
4. Using an appropriate lifting device, lift the enclosure off the shipping pallet and place over the
mounting studs on the pad.
5. Secure the enclosure to the pad using four (two front, two rear) stainless steel flat washers,
lock washers, and nuts.
6. Trim the vapor barrier material with an appropriate cutting tool.

3. 2 Utility Powering
•The XM2 Power Supplies are powered by either 120VAC or 240V AC (120/120 grounded neutral) att ached to
an internal service entrance. The size of the service conductors must be based upon the actual size of the
utility service, and must comply with applicable electrical code requirements.
•Proper grounding is critical. A qualified electrician should verify that grounding complies with applicable
electrical codes. All applicable codes must be adhered to when installing a system, pouring concrete, or
placing a preformed pad. Local codes supersede any procedures outlined in this document.
•The following should be performed only by qualified service personnel and in compliance with local electrical
codes. Verify electrical codes prior to inst allation. Codes may vary and contain specific conduit and wire
sizes for connection to the service entrance. Connection to utility power must be approved by the local utility
before installing the power supply .
•All mounting hardware should be stainless or galvanized, depending on local environmental
conditions. Use of improper hardware may cause corrosion not covered under warranty.
•Soil conditions vary and may affect the integrity of the p ad. Alpha Technologies recommends that
proper steps be taken to ensure that the soil supporting the pad is stable. Improper installation of
the pad may cause uneven settling or cracking not covered under warranty.

1. Remove the two screws on the face of
the SPI and lift off the cover to gain
access to the seizure screw assembly .
Loosen the seizure screw several turns,
so the stinger will pass through the
clamp.
3, Insert the coaxial termination into the
output port on the bottom of the SPI.
Ensure that the stinger goes through
the seizure screw assembly. Tighten
the coaxial termination.
4. Tighten the seizure screw to 35 inchpounds. Replace the SPI cover and
screws. Ensure the switch on the top
or the SPI is in the ON position, the
AUX position is used only when an
alternate power source is connected to
the Jones connector on the top of the
SPI.

The cooling fan is required whenever an XM2-915 or 922 is installed in a UPE-M6 or M8 where the
average temperature of any month exceeds 95°F (35°C).
Install the optional Enclosure Cooling Fan (ECF) using four #8-32 Keps nuts (included) on existing
threaded studs (upper left corner for the UPE-M8, and upper right corner for UPE-M3 and UPEM6). Plug one end of the supplied “Y” cable into the output connection of the power supply , and
connect the other end to the wire leading from the SPI. Connect the fuse end to the fan wire kit.
The cooling fan is thermostatically controlled to turn on at 1 10°F (43°C), and of f at 80°F (27°C).
Replace fuse only with 1/4” X 1-1/4”, 5A, 250V (Alpha P/N 460-025-10).
