Preface
Battery Safety Notes
Chemical Hazards
Any gelled or liquid emissions from a Valve-Regulated Lead-Acid (VRLA) battery is
electrolyte which contains dilute sulfuric acid which is harmful to the skin and eyes; is
electrically conductive; and is corrosive.
If electrolyte contacts the skin, wash immediately and thoroughly with water .
If electrolyte enters the eyes, wash thoroughly for 10 minutes with clean water or a
special neutralizing eye wash solution and seek immediate medical attention.
Neutralize any spilled electrolyte with the special solutions contained in a “spill kit” or with
a solution of 1 lb. Bicarbonate of soda to 1 gal. of water . Report accident, and seek
medical attention if necessary.
Fire, Explosion, and Heat hazards
Lead acid batteries can contain an explosive mixture of hydrogen gas which can vent
under overcharging conditions.
Do not smoke or introduce sparks in the vicinity of the battery .
Prior to handling the batteries, touch a grounded metal object, such as the rack, to
dissipate any static charge that may have developed in your body.
Do not charge batteries in a sealed container. The individual batteries should have 0.5
inches of space between them to allow for convection cooling. If contained, assure the
container or cabinet and room have adequate ventilation to prevent an accumulation of
potentially dangerous gas.

1.1 Site considerations
The site must be planned so that the enclosure will receive good air flow. If
possible, in areas of extreme heat, it is best to position the enclosure so that it
will be shaded from the afternoon sun. 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 v ents.
In areas of potential flooding, the geographical site and concrete pad must be
located above the flood 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 inches in the front and 36 inches 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.
1. Pre-Installation
The concrete pad dra wing pro vided 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 v apor barrier material (such as 30 lb. felt, neoprene pond liner, or heavy
grade tar paper) must initially extend at least 6" in all directions around the
perimeter of the enclosure and be trimmed closer to the enclosure.
WARNING: 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.
T r ansporting the unit with batteries installed may
cause a short circuit, fire, 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 warr anty.
The batteries used in this application may vary slightly depending upon
optional configurations, battery types, or customer requirements. The batteries are
typically gelled-electrolyte, valve-regulated such as the Alpha Cell. Should a
battery be found damaged, refer to the battery manufacturer's documentation
regarding the safe handling of the battery .

2.4 Utility Power Connection
Wiring the Utility Service
Utility power enters the enclosure through the side or bottom of the UPE. The enclosure
accepts a standard electrical fitting. The UPE Series can be equipped with an optional circuit
breaker assembly located in the enclosure’ s module compartment.
CAUTION: The “Utility Power Connection” procedure must ONLY be performed by qualified
service personnel and in compliance with local electrical codes and common
safety practices. Connection to utility power must be approved by the local
utility before installing the power supply.
NOTE: CSA and NEC require that a service disconnect switch be provided
by the installer and be connected between the power source and the ALPHA
power supply. Connection to the power supply m ust include an appropriate
service entrance weather head.
NOTE: A “high-magnetic” trip circuit breaker must be used in order to accommodate
the high-inrush currents normally associated with the start-up of
ferroresonant transformers (400 Amp, no-trip, first-half cycle). Do not replace
this circuit breaker with a conventional service entrance circuit breaker . Alpha
recommends Square D circuit breakers ONLY, because of increased reliability
in this powering application.
Alpha Technologies offers a high-magnetic Square D circuit break er, meter , and a BBX
option. Contact your local sales representative for more information.
Wiring: (from duplex receptacle to service disconnect)

Procedure:
NO T E : For enclosures with multiple battery strings, the 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.
1. Attach the RTS Probe to the inner side of battery #3 (Fig. 2-6), or
battery #4 (Fig. 2-7) on the upper tray, with adhesive tape.
2. The other side of the RTS Probe is attached to the front panel of the
XM2 power supply, in the jack labeled TEMP PROBE.

2.9 Battery Heater Mat, and LRI-ACI Lamp Option
Battery Heater Mat Option
Battery Heater Mats are designed to increase battery capacity in cold environments. To install the
mats:
The heater mat is thermally fused at 180o F. The thermostat is set to open on rise at 50o F, and close
at 40o F.
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 flashes 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
climb the pole and open the enclosure. Connect the LRI lamp to the jack on the front of the power
supply labeled LRI.
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.
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. This allows a
cable technician to drive by and determine the status of the power supply without having to climb the
pole. Connect one connector of the A CI lamp to the OUTPUT 1 jac k on the front of the power supply,
and the other to the SPI.
