Product Description
Product Description
Integrated Power Centers (IPCs) manufactured by Square D combine power

distribution and controls into one integrated package. The IPC may consist of
I-LINE power panels, NQOD, NF, and POWERLINK lighting and appliance
panels with starters, relays, timers, power meters, circuit monitors, TVSS
units, lighting contactors, HVAC controller, energy management systems,
lighting controls, time clocks, transformers, and power conditioners.
Integrated Power Centers are suitable for use on ac systems through 480 V
and can be applied as service entrance equipment. IPCs are Underwriters
Laboratories® (UL®) Listed under file E83877.
Integrated Power Center Installation and Space Savings

A variety of Integrated Power Center configurations are available with
stacked circuit breaker panelboards and space for other control devices. This
new approach with integrated switchboards reduces installation space and
time by preconfiguring and assembling the system in vertical sections at the
factory before arrival at the job site.
The IPC eliminates panelboard connectors and conduit between power and
lighting panels. The outcome is a lowered installation cost and a reduction in
construction cycle time; therefore, the store or facility will open sooner, and
revenue will be derived faster on the investment.

General and Application Information
The Integrated Power Center is designed to reduce space and installation time. The conductors from
the power distribution to the lighting and control circuits are made at the factory. The sections are bolted
together and shipped in large section splits to reduce installation time. When lineups are too large to
ship as one section split, the connections between the sections are pre-measured, cut, striped and
color-coded for easy installation.

control devices, such as occupancy sensors, low voltage variety of capabilities, depending on your application needs. System features
switches, inputs from external building systems, and are listed below:
photo sensors.
500 Level System
The 500 level system is designed to be used in conjunction with other control
devices such as external time clocks, access systems, occupancy sensors,
or other building systems that provide either dry-contact closures or digital
serial communications. In response to these commands, the controller will
automatically switch a programmed group of lighting circuits. The controller
also contains both RS-232 and RS-485 communication ports and can be
easily interfaced with a building automation system.
1000 Level System
The 1000 level system includes all the features of the 500 level system and
incorporates a flexible time scheduler that eliminates the need for external
time clocks. This time scheduler includes many control features that are not
found in traditional, mechanical time clocks or energy management systems.
These features include automatic daylight savings adjustments, sunrise and
sunset tracking according to geographic location, and special events that will
run only on specific dates. The 1000 level system is ideally suited for stand-
alone systems in retail, office, institutional, and industrial facilities.
2000 Level System
The 2000 level system combines the control, input, and scheduling features
of the other systems with the added benefit of embedded Ethernet
connectivity. This provides the ultimate in control capabilities and
communication with a true peer-to-peer (P2P) control network that allows
different controllers to share input signals, schedules, and lighting zone
states. For instance, the status of a photo sensor input connected to one
controller can be shared across multiple panels, allowing this single sensor
input to control branch circuits in other 2000 level POWERLINK panels
located throughout a facility. Using Ethernet connectivity, network installation
Setup is easily accomplished, either from the keypad or costs are reduced by eliminating the need for a dedicated lighting control
from easy-to-use Windows-based software network. The network can be maintained by your existing network support
staff. This helps reduce operating costs and improve reliability, since
maintenance of the network requires no special networking skills that are
usually associated with a dedicated lighting control network.

Dimensions
Structure and Dimensions
The Integrated Power Center frame is designed to provide a sturdy platform to build switchboard products. Individual sections are
built from one formed top, bottom and rear plate, and separate side plates. Side plates between sections have three
6.25 in. x 22 in. cutouts for connections between sections. Solid side closure plates are designed for the left- and right-most
sections. Section doors are provided with three-point latch assembly with locking provisions and optional doors over panel interiors
for complete front accessibility.
Section dimensions are determined by the type, size, quantity, and arrangement of components and devices installed within the
section. The Integrated Power Centers are designed to rear-align and match up with POWER-STYLE QED switchboards when
the system ampacity is greater than 1200 amperes. IPCs are also designed to be rear-aligned and match with transformer
assemblies when applications require integrated transformers.
IPCs are available in NEMA Type 1 indoor enclosures. IPC sections can be moved into place using rollers or lifting hooks.
