A “Caution” identifies conditions and actions that may damage the power
supply or associated equipment.
Warnings
NOTE: This power supply and its associated hardware (enclosure, batteries, cabling)
may contain equipment, batteries or parts which have accessible hazardous
voltage or currents.
T o avoid injury:
•This power supply and its associated hardware must be serviced by authorized personnel
only .
•The enclosure which contains the power supply and associated equipment must remain
locked at all times, except when authorized service personnel are present.
•Remove all conductive jewelry or personal equipment prior to servicing equipment, parts,
connectors, wiring, or batteries.
•Read and follow all installation, equipment grounding, usage, and service instructions
included in this manual.
•Use proper lifting techniques whenever handling equipment, parts, or batteries.
•Batteries contain dangerous voltages, currents and corrosive material. Battery installation,
maintenance, service and replacement must be performed by authorized personnel only .
•Never use uninsulated tools or other conductive materials when installing, maintaining,
servicing or replacing batteries.
•Use special caution when connecting or adjusting battery cabling. An improperly connected
battery cable or an unconnected battery cable can result in arcing, a fire, or possible
explosion.
•A battery that shows signs of cracking, leaking or swelling must be replaced immediately by
authorized personnel using a battery of identical type and rating.
•Avoid any contact with gelled or liquid emissions from a valve-regulated lead-acid (VRLA)
battery. Emissions cont ain dilute sulfuric acid which is harmful to the skin and eyes.
Emissions are electrolytic, which are electrically conductive and are corrosive. Follow the
Chemical Hazards notes if contact occurs.

Battery Safety Notes
Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery
installation, maintenance, service and replacement must be performed by authorized personnel
only.
Chemical Hazards
NOTE: Any gelled or liquid emissions from a V alve-Regulated lead-acid (VRLA)
battery contain dilute sulfuric acid, which is harmful to the skin and eyes.
Emissions are electrolytic, which are electrically conductive and
corrosive.
•If any battery emission contacts the skin, wash immediately and thoroughly with water .
Follow your company’s approved chemical exposure procedures.
Preface
•If any battery emission contacts the eye, wash immediately and thoroughly with water for
10 minutes with pure water or a special neutralizing eye wash solution and seek
immediate medical attention. Follow your company’s approved chemical exposure
procedures.
•Neutralize any spilled battery emission with the special solution contained in an approved
spill kit or with a solution of 1 lb. bicarbonate of soda to 1 gal. of water. Report chemical
spill using your company’s spill reporting structure and seek medical attention if
necessary.
•Always replace batteries with those of an identical type and rating. Never install old or
untested batteries.
•Do not charge batteries in a sealed container . Each individual battery should have at least
0.5 inches of space between it and all surrounding surfaces to allow for convection
cooling.
•All battery compartments must have adequate ventilation to prevent an accumulation of
potentially dangerous gas.

1. Introduction
1.1 Enclosure Introductions
The CESC enclosure is a cost effective 'all in one' power system. The side car provides for a
single power module, batteries, and generator in a low profile minimum footprint design.
This procedure describes the installation of a side car to an AlphaGen generator, PN-3B or
CE3X2B enclosure.

2. Installation
2.1Concrete Pad Preparation
Pads can either be poured on site, or precast by Alpha T echnologies. The mounting holes on
the bottom of the high security PN-3 will fit both a standard PN-3 pad, and a CE3X pad.
Precast pad model number PCC-SC-3X, Alpha P/N 641-061-10 or PCD-SC-3X, Alpha P/N
641-064-10 (east coast) are available for this system.

A 25+ year continuous vapor barrier must be used between the enclosure and the 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 t ar
paper) must be initially extended at least 6" in all directions around the perimeter of the
enclosure. Af ter the enclosure is secured to the pad, the material can be cut closer to
the enclosure, using the appropriate knife or cutting tool.

2.2 Utility Power Connection
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:UL and NEC require that a service disconnect switch (UL listed) be provided by the
installer and be connected between the power source and the ALPHA power supply .
Connection to the power supply must include an appropriate service entrance weather
head.
Wiring the Utility Service
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 ONL Y , because of increased reliability in this powering application.
Alpha Technologies offers a high-magnetic Square D circuit breaker and a BBX option (a UL Listed
service entrance). Contact your local sales representative for more information.

2.4Internal Components
The Sidecar enclosure contains an Input Power Panel (IPP), one or two Service Power Inserters
(SPI),and the Enclosure Grounding Rail. The Power Supply rests on the upper shelf, and a
36 or 48 VDC battery pack on the lower two shelves.
A cooling fan is required any time a Power Supply is housed in the side car. The
fan is thermostatically controlled to turn on at ~140 deg F and off at ~110 deg
F. The fan cable has a 'T' connector that attaches to the Power Supply output
connection. Replace fuse only with a 1/4” X 1-1/4”, 5 Amp, 250 Volt
(Alpha P/N 460-025-10).

3. Verify that the Battery Breaker on the front of the power supply is in the OFF
position.
4. Plug the AC power cord into the Input Power Panel on the side of the enclosure.
5. Plug the Battery Input Cable from the battery pack into the Battery Input
connection on the front of the power supply .
6. Plug the wire leading from the fan into the OUTPUT 1 connection on the front of
the power supply .
7. Plug the wire leading from the top SPI into the other set of plugs on the wire
from the fan.
8. If a second SPI is installed, plug it into the OUTPUT 2 connection on the front of
the power supply .

2.7Battery Remote Temperature Sensor (RTS)
Tools Needed:
Adhesive T ape
Procedure:
For enclosures with multiple battery strings, the RTS must be located
with the WARMEST 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. In this application, the RTS
MUST be attached to a battery in the upper tray of the side-car .
1.Attach the RTS Probe to the inner side of one of the batteries
on the upper tray of the side-car 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

2.8Service Power Inserter
1. The SPI box(es) are mounted on the shelf
support bracket.
2. 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 that the
stinger will pass through the clamp. (Fig 2-3)
3, Insert the Coaxial T ermination into the output
port on the bottom of the SPI. Ensure that
the stinger goes through the Seizure Screw
Assembly. Tighten the Coaxial T ermination.
4. Tighten the seizure screw to 35.0 Inch-Pounds.
Replace the SPI cover and screws.
Ensure that 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 SPI.
