CAUTION!

The use of CAUTION indicates safety information intended to PREVENT DAMAGE to material or
equipment.

WARNING!

WARNING presents safety information to PREVENT INJURY OR DEATH to the technician
or user.

Safety Precautions

• Only qualifi ed personnel may service the APB Voltage Booster.

• Verify the voltage requirements of the equipment to be protected (load), the AC input voltage to the voltage
booster (line), and the output voltage of the system prior to installation.

• When connecting the load, DO NOT exceed the output rating of the voltage booster.

• Always use proper lifting techniques whenever handling units.

• Avoid using uninsulated tools or other conductive materials when working inside the enclosure.

• Remove all rings, watches and other jewelry before servicing voltage booster.

1.0 System Overview

1.1 Introduction

The Alpha Power Booster (APB) was created to improve network effi ciency and reduce life
cycle cost by eliminating lightly loaded power supplies at the end of long amplifi er cascades.
The voltage booster accomplishes this by boosting end-of-line voltages. The voltage boost
allows deeper penetration of the HFC network and eliminates the need for power supplies
and batteries near the end of the HFC network.
