INTRODUCTION

This manual describes the PowerWorx® Type 70 Series Power Distribution Panels and provides installation, test, operation, and maintenance procedures. Two types of PowerWorx Type 70 power distribution fuse panels are available: thetraditional power distribution fuse panel and theuninterrupted power distribution fuse panel. Within this manual, the fuse panels are referred to as the “traditional fuse panel” and “uninterrupted fuse panel.”

Standards

Type 70 series fuse panels are compliant with all major standards including UL, NEC 1999, and CSA standards. The fuse panel design places great emphasis on high reliability and simplicity of operation.

Admonishments

Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence.

Danger: Danger is used to indicate the presence of a hazard thatwill cause severe personal injury, death, or substantial property damage if the hazard is not avoided.

Warning: Warning is used to indicate the presence of a hazard thatcan cause severe personal injury, death, or substantial property damage if the hazard is not avoided.

Caution: Caution is used to indicate the presence of a hazard thatwill orcan cause minor personal injury or property damage if the hazard is not avoided.

General Safety Precautions

-

Caution: The fuse panel uses electrical voltage and amperage levels which, perGR-1089,may be considered an electrical hazard. Care should be exercised to assure that only qualified personnel are allowed to install, operate, maintain, or otherwise come in contact with this equipment when the panel is energized. Only insulated tools should be used on energized elements of the panel.

Caution: All fuse panel wiring and cabling should be connected with the system office battery input off or disconnected at the office distribution panel.

Caution: A replacement fuse must be the same type and must have exactly the same current rating as the fuse being replaced.

Important Product Features

Both the traditional and uninterrupted fuse panel provide dc power over two separate buses (feeds). However, with the uninterrupted fuse panel, when one bus loses input power, the other bus supplies the output power for both buses.

Application: Type 70 series fuse panels are used to supply protected dc power to the various types of telecommunications products typically used in central offices, multimedia headends, remote sites, and other locations.

Input Power: Type 70 series fuse panels contain two buses (feeds) that accept–24Vdc or–48Vdc input power. The traditional fuse panel is rated at 65 Amps input current per bus for a total output current of 130 Amps per fuse panel. The uninterrupted fuse panel is rated at 60 Amps input current per bus but the total output current cannot exceed 60 Amps per panel. Duringback-upoperation, the uninterrupted can supply an output current of up to 30 Amps per bus or one half of the 60 Amps input current provided by the working power source.

Output Power: Type 70 series fuse panels provide fuse protected output power with up to 8 fuse positions per bus. The selectable current rating for each fuse can be standard amperage capacity type 70 fuses up to 10 Amps.

Type 70 series fuse panels incorporate several important features:

Self-configuringinput voltage(–24Vdc or–48Vdc) capability with up to 65 Amps per bus (traditional fuse panel) and 60 Amps per bus (uninterrupted fuse panel) to simplify installation and allow their use in most dc voltage applications

A colored indicator that projects from the center of a blown type 70 fuse to quickly and easily identify the affected fuse position

Alarm contact connections built into the fuse panel for connection to external visual, audio, and remote alarms

Field-replaceablehigh-brilliancePower-Ongreen and Alarm red LED indicators

Easily-removablesmoked plastic protective cover over connectors to enhance safety and panel accessibility

Two-postgrounding to ensure robust and reliable ground connectivity

Standard Equipment

Type 70 series fuse panels have two power buses (feeds). The capacity of each bus is eight fuse positions with up to 10 Amps per fuse position (within the maximum bus capacity). Each bus has Power-Onand Alarm indicators on the front of the chassis and input, output, ground, and alarm contact connections on the rear of the chassis.

The current capacity of each bus of the traditional power fuse panel is 65 Amps maximum (130 Amps per panel). The current capacity of each bus of the uninterrupted power fuse panel is 60 Amps maximum (60 Amps per panel).

The power dissipation of each fuse panel is 40 watts maximum at 130 Amps.

The dimensions of each fuse panel are 1.75 inches (4.45 centimeters) high, 17.13 inches (43.51 centimeters) wide, and 10.01 inches (25.42 centimeters) deep (does not include depth of protective cover and connectors, fuses, and visual indicators that extend beyond the chassis.

Two sets of mounting brackets are provided with each fuse panel, one set for 19-inch(48.3 cm) rack installations and one set for23-inch(58.4 cm) rack installations. The fuse panel can be flush or recess mounted in equipment racks with WECO or EIA hole spacing.

A typical traditional power fuse panel with protective cover in place is shown in Figure 1. A typical uninterrupted power fuse panel with protective cover in place is shown inFigure 2.

Fuse panels are shipped without fuses. The required fuses are available separately as accessory items.

Options

All fuse panels are available with the following options:

Two types of output connectors: screw-downterminal strip connectors or set screw barrel terminal strip connectors

Two types of input connectors are available: two-holecompression-lug(stud-type)or set screw barrel connectors

The fuse panel color is either putty white or black color

Accessories

The following accessories are available:

Standard type 70 fuses with standard values from 0.2 Amp to 10.0 Amps

Cable management bar kit

Four sizes of compression connector lugs for input power connections

Fused equipment designation card kit

Fuse designation card kit
