INTRODUCTION

This manual describes the PowerWorx
hereinafter called "circuit breaker panel" or "panel." A complete description of the circuit
breaker panel and its available options and accessories is provided plus the information required
to install, test, and operate the circuit breaker panel.
Application: The circuit breaker panel is a high current (100 Amps per bus) circuit breaker type
power distribution platform. The circuit breaker panel may be used to supply protected dc
power to the type of telecommunications products typically installed in central offices,
multimedia headends, remote sites, and other locations.
Input Power: The circuit breaker panel contains two buses (feeds) that accept either –24 Vdc or
–48 Vdc input power (both buses must have the same voltage) of up to 100 Amps per bus for a
total of 200 Amps per panel.
Output Power: The circuit breaker panel provides circuit breaker protected output power with
up to 8 circuit breaker positions per bus. The current rating for each circuit breaker may be 1, 3,
5, 10, 15, or 20 Amps (see

Standards

The circuit breaker panel meets UL, Telcordia (formerly Bellcore), NEC 1999, CSA, NEBS
Level 3, IEC, and CE standards.

Important Features

The circuit breaker panel incorporates the following important features:
• Self-configuring voltage (–24 Vdc or –48 Vdc) capability and up to 100 Amps per bus to
simplify installation and allow one panel to fit most dc voltage applications
• ON/OFF lettering on each circuit breaker for quick identification of tripped circuit
breakers as well as ampere ratings
• Eight circuit breaker positions per bus (field-replaceable)
• Alarm contact connections built into the circuit breaker panel for external connection to
visual, audio, and remote alarms
• Two field-replaceable high-brilliance Power-On green LED indicators and two Alarm red
LED indicators (not field-replaceable)
• Easily-removable (turn four screws) plastic protective cover over connectors to enhance
safety and panel accessibility
• Two-post grounding to ensure robust and reliable ground connectivity

Standard Configuration

The standard configuration circuit breaker panel has two power buses (feeds), with each power
bus having multiple circuit breaker positions. The two buses are duplicates of each other in the
number and type of circuit breakers. The capacity of each bus is one to eight circuit breakers.
Each bus has Power-On and Alarm indicators on the front of the chassis and input, output,
ground, and alarm contact connections on the rear of the chassis.
