APP60S (Service Power Supply)
The APP60S is a portable, non-standby power supply used to provide conditioned AC
power to the load when the main power module is out of service. A front panel switch
allows the APP60S to be set for 30 VAC or 60 VAC applications. Used in conjunction with
the “Jones” connector and "ALT/ON" switch located on the enclosure's SPI (Service Power
Inserter), power can be transferred from the main module to the APP60S without interrupt-
ing the load.

Batteries
Sealed, gelled electrolyte (no maintenance) batteries are recommended for use with
XP Series uninterruptible power supplies. The majority of Cable Television and Broadband
LAN operators prefer this type of battery due to its exceptional performance, safety record
and service life. Batteries are available in ratings of 75Ah and 100Ah.
5.19
ABC-12 (Battery Charger)
The ABC-12 is designed for use with 12 volt specialty batteries such as gelled electro-
lyte products used in communications, UPS and standby applications. Selectable float or
equalize charge modes optimize battery recharging. The charger is ideal for recharging
batteries that have been in lengthy storage, plus batteries can be re-balanced using a
parallel charge before use in series applications.

Enclosures
The XM Series power module can be used in either pole or ground-mount installations.
Pole-mount enclosures, PME (for cold climates) and PWE (for warm climates), are con-
structed of heavy-duty aluminum and come with two, galvanized steel mounting brackets.
UPE and UPE/M ground-mount enclosures are constructed of heavy-duty aluminum and
come with Galvanized (UPE/M only) steel doors. Alpha enclosures are vented to promote
natural convection cooling and prolong battery life.
Alpha enclosures contain separate compartments for the batteries and power module.
The battery compartment accommodates (3) Group 31 gelled-electrolyte, no-maintenance
batteries and is equipped with a battery slide tray (except PME) for easy access. The
module compartment accommodates the power module, a 15 Amp "HM" circuit breaker
assembly, duplex receptacle and SPI (Service Power Inserter). The AC power connection
to the breaker assembly is made through a conduit knockout on the rear of the PWE
enclosure or through the base of the PME, UPE and UPE/M. The cable connection is
made directly to the SPI’s "VSF" coaxial fitting located on the rear of the PWE, or at the
base of the PME, UPE and UPE/M. There is adequate space in the module compartment
to accommodate a variety of power modules, indicator lamps, and components used for
status monitoring.
5.21
PS Series (Pedestal Supports)
Alpha pedestal supports provide a quick, one-step solution for ground-mount enclosure
installations. Constructed of pre-formed, high density polyethylene (HDPE), the pedestal
support eliminates the need for costly concrete work. The large body design provides
excellent "hand hole" working space, allowing room for cable bends, wire loops and
grounding connections. Pedestal supports are available for use with Alpha UPE, UPE/M,
PWV/PED, PED/M and PMD/PED ground-mount enclosures.
5.22
DataLogger
The hand held DataLogger is used to run diagnostics, manipulate the APM (Automatic
Performance Monitor), and to test individual battery voltages. Maintenance data, such as
Input Line Voltage, Output Current, Battery Voltage, Battery Charge Voltage (float and
equalize), Battery Charge Current, Inverter Events, Accumulated Inverter Run Time,
Technician ID Number, Power Supply Address, Test Date and Time, can be retrieved and
stored in the DataLogger. Data from as many as 32 power supplies can be downloaded to
a DOS compatible computer at the headend to create a maintenance history file, thus
automating data retrieval, log entry and consistent data formatting.
