2.0 Installation
2.1 Site Considerations
• The site must be planned so the enclosure receives good air fl ow. If possible, in areas
of extreme heat, it is best to position the enclosure so that it will be shaded from the
afternoon sun. If no shade is available, a factory installed fan kit is highly recommended.
In areas of prevailing winds, it is best that the enclosure be located so that the sides of
the cabinet face the winds instead of the doors. This will greatly reduce the buildup of
sand or snow against the enclosure’s air vents.
• In areas of potential fl ooding, the site must be located above the 100-year fl ood plain.
• The enclosure must be placed where it will be free of obstructions, allowing easy access
to the doors for service or equipment access. For ventilation and maintenance, allow a
minimum space of 36" (914.4mm) in front, and 36" (914.4mm) in the rear between the
enclosure and other solid structures.
• Place the enclosure well away from sources of forced water, such as underground
sprinkler systems and direct roadway splash.
• The concrete pad drawing provided in this manual contains all of the required mounting
details, including electrical service and cable plant entrances.
• For ease of installation, lightweight polymer concrete pads are available from Alpha
Technologies for all UPE series enclosures.
• The vapor barrier material (such as 30 lb. felt, neoprene pond liner, or heavy grade tar
paper) must initially extend at least 6" (152.4mm) in all directions around the perimeter of
the enclosure and be trimmed closer to the enclosure.
• Contact local utilities or cable/piping locator services to ensure that the installation does
not interfere with existing cables or piping.
2.2 Transportation and Lifting
A safe means of transportation to the site and a safe procedure for unloading the enclosure
is necessary. At least two installation personnel are required to place the enclosures on the
pad. Installation team must assess the transport path for all obstructions. An obstruction free
path should be selected for transport. Use safe lifting practices. Electronic modules, batteries
or other components must not be installed until the enclosure is securely set in place at its
permanent location.
• Never transport the unit with batteries installed. Batteries must ONLY be installed after the unit
is transported to the site and secured to the pad. Transporting the unit with batteries installed
may cause a short circuit, fi re, explosion, and/or damage to the battery pack, enclosure and
installed equipment. Damage caused by improper shipping or transporting a unit with batteries
installed is not covered by the warranty.
• Enclosure must always remain in the upright position during the shipping, storage and
installation process. Damage may result from enclosure being shipped or stored on its side.
• DO NOT lift the enclosure by the cover, unless empty.
13031-124-C0-004, Rev. D
Page 14
2.0 Installation, continued
2.3 Enclosure Installation
Follow the procedure below for attaching the enclosure to a pedestal support or precast pad.
Tools and Materials Required:
• Ratchet set with 6" (152.4mm) extension.
• Vapor Barrier
• Utility Knife
CAUTION!
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 paper) should initially extended
at least 6" (152.4mm) in all directions around the perimeter of the enclosure and later be trimmed
closer to the enclosure.
Procedure:
1. Unwrap the enclosure and inspect the contents. If items are missing or damaged, contact
Alpha Technologies and the shipper immediately.
2. Place the vapor barrier material on the pad.
3. Unbolt the enclosure from the shipping pallet.
4. With no less than two installation personnel, lift the enclosure off the shipping pallet and
place over the mounting studs on the pad.
5. Secure the enclosure to the pad using the hardware supplied with the precast pad or
pedestal support.
6. Trim the vapor barrier material.

WARNING!
To prevent arcing, never allow live battery cables to make contact with the enclosure.
Disconnect battery leads, or wrap the cable lugs with electrical tape.
CAUTION!
Threaded insert terminals require the use of 3/4" (19mm) bolts. The use of 1" (25.4mm) bolts will
seriously damage the battery. The only exception is the terminal with the large spacer for the in-line
fuse link. See Section 2.9.3 for details.
NOTE:
In battery confi gurations made up of multiple battery strings, Alpha recommends the use of in-line fuses.
Procedure:
1. Place the batteries on the enclosure’s battery slide tray or battery shelf. The correct
arrangement of the batteries on the tray or shelves varies between enclosure
models. See Figs. 2-8 and 2-9 for the correct battery arrangement. Leave a
minimum of one inch of ventilation space between the batteries.
2. To make identifi cation and record keeping easier, number and label the batteries.
Record each battery’s number and date code in the power supply maintenance log.
3. Using the battery arrangement diagrams as a reference, connect the batteries in
series to achieve 36Vdc. Refer to the diagrams for the location of the optional inline fuses. For AlphaCell batteries, torque terminal connections to approximately
65 in-lbs (7.3 Nm) at installation and re-torque to 50 in-lbs (5.6 Nm) during routine
maintenance. For non-Alpha batteries, torque to manufacturer’s specifi cations.
4. Verify the batteries are properly connected by checking the polarity and voltage
of the battery cable connector with a digital voltage meter. DO NOT connect the
battery string or strings to the power supply at this time.
5. The power supply battery charger collects battery temperature compensation
information with a Remote Temperature Sensor (RTS) attached to one of the
batteries. Refer to the Fig. 2-7 or Fig. 2-8 to determine the RTS attachment point.
See Section 3.1 for RTS the attachment procedure.
6. Route the battery cable connector into the power supply compartment. DO NOT

For enclosures with multiple battery strings, the Remote Temp Sensor (RTS) must be located with
the warmest (normally the topmost) battery string. This ensures proper operation of the battery
charger’s temperature compensation circuit. Failure to locate the RTS with the warmest battery
string could result in overcharging and premature battery failure.

3.2 Lightning and Surge Arrester Options
Alpha’s LA Series voltage suppressors provide reliable protection of power supplies and
related equipment from the damaging power line disturbances common to cable TV and
broadband applications. The LA Series incorporates Metal Oxide Varistor (MOV) technology
that effectively limits voltage surges and absorb excessive energy levels. Housed in a durable
polymer casings with standard electrical plugs, the LA Series plugs directly into any electrical
outlet.

The ISA-120/240 Secondary Surge Arrester (Alpha P/N 062-041-10) is hard-wired and
protects electrical equipment and wiring against lightning induced surges. The arrester diverts
lightning surges to ground, and is designed to handle repetitive operations. Severe lightning
can cause the device to fail, and it should be replaced if either of the LEDs fails to light.

3.3 Battery Heater Mat
Battery heater mats are designed to increase battery capacity in cold environments. The
thermostat is factory set to turn the mat on at 40ºF (4.44ºC), and off as the temp rises above
50ºF (10ºC). As a safety feature, the mat has a thermal fuse that opens at 180ºF (82.22ºC) to
protect the batteries from overheating. To install the mats:
1. Remove the batteries from the tray(s).
2. Place the heater mat in the bottom of the tray(s).
3. Replace the batteries.
4. Plug the AC line cord into the closest receptacle.
3.4 LRI-ACI Lamp Option
LRI Option
The LRI lamp (red lamp) is located on the outside, on either the right or left side of the
enclosure. The lamp comes ON only when the power supply is running on backup power
(STANDBY). During normal AC line operation, the lamp remains OFF. Whenever a fault is
detected, the lamp fl ashes to indicate that service is required. The LRI can be used as a
simple form of status monitoring by allowing cable technicians to check the operational status
of the power supply without having to open the enclosure. Connect the LRI lamp to the jack
on the front of the power supply labeled LRI.
ACI Option
The AC indicator (green lamp) is located on the outside, on either the right or left of the
enclosure. When the lamp is ON, it indicates AC power is available at the power supply
output (normal operation). This allows a cable technician to drive by and determine the
status of the power supply without having to open the enclosure. Connect one connector of
the ACI lamp to the OUTPUT 1 jack on the front of the power supply, and the other to the SPI.
