6.5 System Options
These options can be factory installed or upgraded in the field by the user:
Local and Remote Indicator (LRI)
The red LRI lamp is located on the outside of pole-mount enclosures. Using this simple form of status monitoring
operators can check the operational status of the power supply without having to climb the pole and open the enclosure.
During normal AC line operation, the LRI remains off. The LRI comes on only when the power supply is running in standby
mode. Whenever a fault is detected during Self Test, the LRI flashes to indicate that service is required.
AC Indicator (ACI)
The green ACI lamp is located next to the LRI on the outside of pole-mount enclosures and also acts as a simple form of
status monitoring so cable technicians can check the output status of the power supply without having to climb the pole
and open the enclosure. As long as there is voltage present at the output, the ACI remains on. To provide much longer life
than the original light bulb design, use the ACI-LL (long life LED). Models for 60V and 90V are available. Do not use ACIs
for ground-mount enclosures.
Coaxial Surge Arrestor
Alpha recommends using coaxial surge suppression for enclosure protection. The Coax Surge Protector (Alpha P/N 162-
028-10) includes 75 ohm surge suppressor and mounting hardware.
APP90S/APP9022S (Service Power Supply)
The APP90S/APP9022S is a portable, non-standby power supply that provides conditioned AC power to the load when
the main power module is out of service. An internal tap lets the APP90S/APP9022S be set for 90/75/60VAC applications.
Use a 15A or 25A SPI (Service Power Inserter) to transfer power from the APP9015S/APP9022S to the load.
6.6 Return and Repair Information
In the event you need to return the power supply to Alpha Technologies for service, a Return Material Authorization (RMA)
form must accompany the unit. The form can be found at Alpha’s Web site (www.alpha.com/rma). Follow the instructions
contained in the form to obtain an RMA. Once an RMA number has been issued, pack the unit per instructions and return
to the service center assigned by Alpha Technologies. Or, if preferred, contact Alpha Technologies at (800) 322-5742 for
assistance.
Any information pertaining to the nature of the power supply failure or problem, along with a copy of the power
supply’s maintenance log, should be included with the returned power supply.
