2.2 Inherent Hazards
This product uses electricity and high voltages are present inside the cabinet. This product is equipped with a
lockout/tagout feature on the input circuit breaker to prevent accidentally energizing the product during installa-
tion, maintenance, and/or repair. This product is also equipped with safety interlock circuits, which will de-
energize the product when a cover is removed. In all such cases, hazardous touch voltages will still be present
at the rear of the product’s input circuit breaker where input power feeds are attached. Working on the product
under such circumstances is classified under SEMI S2-0200 as a Type 4 Task. This may be changed to a Type
1 task and complete safety may be assured by disconnecting power to the product (and locking and tagging out)
at the source.

Section 2 - Safety
On both removable side panels, near the top of the panel and approximately in the middle are the following warn-
ings. Each calls attention to a specific hazard requiring special attention.
With the front panel circuit breaker of the power conditioner turned off and locked out, potentially hazardous
touch voltages are confined to the input power conductors at the rear of the circuit breaker. Entering the cabinet
under these circumstances is classified as a Type 4 task under SEMI S2-0200 guidelines. This hazard label
alerts personnel to the need to turn off and lock out power to the power conditioner at the facility source. Doing
so will eliminate all potentially hazardous voltages inside the enclosure. Entering the enclosure under these circumstances if a Type 1 task under SEMI S2-0200.
PLEASE NOTE: After extended operation, internal parts of the power conditioner may become very hot.
This hazard label calls attention to the need for protective gear when entering the equipment enclosure.
Inside the power conditioner enclosure another warning similar to the one
shown at the left warns once again of the presence of very hot surfaces
and the potential for injury and burns. This warning is accompanied by
the legend “CAUTION - HOT SURFACE” and is attached to the upper steel
frame of the isolation transformer on the primary side.

2.4 Safety Interlocks
This product incorporates a safety interlock circuit that functions as a
secondary means of protection for personnel. Protective side panels and
hazard warning labels provide primary protection. However, in the event one
or more side panels are removed from the product prior to being de-
energized, the safety interlock system will de-energize the power conditioner.
The circuit consists of two safety interlock switches (one per each side access
panel) located in the center of the top side frame of the power conditioner.
Section 2 - Safety
The switches operate as a normally open circuit connected to the shunt trip
coil of the input circuit breaker. See Figure A. Activating either of these safety
interlock switches causes a 24 VDC signal to energize the shunt trip coil of the breaker. The 24 VDC signal is
derived from a low voltage, fused tap on the transformer secondary. The shunt trip circuit also uses stored
energy from a capacitive circuit to ensure that the shunt trip mechanism will function even in the event of a power
outage. The safety interlock switches are shown on the general circuit diagram found in subsection 10.1 of
Section 10 of this manual.
If the power conditioner shunt trips as a result of removing the side panels, hazardous voltages will remain at the input voltage connection to the rear of the main cir-
cuit breaker. Entering the enclosure under these conditions is classified as a Type
4 task under SEMI S2-0200 guidelines. This can be changed to a Type 1 task by disconnecting power at
the source before entering the enclosure.
Figure A
2.5 Lockout/Tagout
The rotary handle of the main breaker is equipped with a
hinged center insert clearly identified with an arrow. The
rotary handle of the main breaker must be in the horizontal
position to proceed. See Figure B. Depress the insert on
the arrow on the left hand side causing the insert to extend
on the right revealing a slot to accommodate a locking
device as shown in Figure C. The lockout/tagout feature is
designed to prevent personnel from accidentally energizing
the power conditioner while maintenance, service or repair
is being performed. With the lockout/tagout engaged, hazardous voltages are still present at the rear of the input
circuit breaker where input power feeds connect to the power conditioner. Entering the enclosure under these
circumstances is classified as a Type 4 Task under SEMI S2-0200. Entering the enclosure may be classified as
a Type 1 Task if power is disconnected from the power conditioner at the source.

Section 3 - Product Overview
Welcome to the world of conditioned power. Electrical power users from around the world benefit from the use of
clean, quality power. That's why we developed the Conditioned Power Center (CPC). The CPC Series is a low-
impedance power conditioner that provides high peak-load capability. You'll find that we've engineered these
products to provide features not readily available as standard equipment on other three-phase power line
conditioning products. The CPC series of products provide the functionality and flexibility that your business
needs in a power quality solution-both now and in the future.
3.1 Product Purpose
The CPC is designed to eliminate high-frequency noise and high-voltage impulses (also known as spikes or
surges) from the AC power that runs your electronic equipment. The power conditioner installs between the
power source and the critical load. And because it is a three-phase device, the CPC provides protection for all
transformer phases that power a large system. Sophisticated electronic systems contribute to the profitability of
your business, and clean power is an essential element in their reliable operation. Each electronic system
responds to power-quality problems differently, but properly protected systems benefit in a variety of ways. These
benefits include fewer hardware failures, fewer "no problem found" service calls, less system downtime, higher
manufacturing yield, better image quality and longer equipment life.
The CPC power conditioning series incorporates these three important power quality elements:
1. A low-impedance isolation transformer - The transformer is the "heart" of the power conditioning system. It
provides unequaled protection against common mode (neutral to ground) disturbances and voltages. In addition,
it provides all the criteria necessary to meet National Electrical Code 250-5d requirements for a "separately
derived power source." The isolation transformer can be specified to accommodate the variety of electrical supply
voltages and frequencies that are encountered throughout the world.
2. A low pass filter - The filter is responsible for removing normal mode (phase to neutral and phase to phase)
noise components from the electrical power. These power disturbances are the ones that are caused by your
system's "electrical neighbors" (i.e. elevators, copy machines, motors, HVAC equipment and even other
computer systems).
3. A surge diverter - The surge diverter is part of the input (primary) circuit of the isolation transformer. This
ensures that any voltage impulses generated within the facility (our outside of it due to occurrences like lightning
and utility activities) do not interfere with the connected system. Although the surge diverter is designed to
handle substantial energies, catastrophic events may occur, which damage one or more of the circuit’s protective
elements. If such damage occurs, one or more of the TVSS Fault LEDs on the power conditioner’s front panel
will illuminate. Consult Section 8.1.3 for instructions on how to proceed if a TVSS Fault LED illuminates.

over-current protection) may be added to the CPC power conditioner.
Distribution panels - This option is available only on models 85 kVA and larger. It provides a standard 42 circuit
Square D panelboard from which the conditioner’s power may be distributed to individual branch circuits each
with their own dedicated circuit breaker.
External EMO connector - This optional connector (if so equipped) is part of the power conditioner’s EMO
(emergency machine off) circuit. It provides a point for connecting the power conditioner’s EMO circuit to an
external control or the master EMO circuit of a computer room or similar facility. See Section 7.3
Seismic anchorage brackets - This options permits stabilization of the power conditioner in seismically active
(earthquake prone) areas. Seismic design data is included in the specification sheet found in Section 10.
A 5th harmonic filter - The GPI Series 2000 may be ordered with an optional passive 5th harmonic filter. When
so equipped, the CPC will significantly reduce the fifth odd order harmonic current regardless of origin (line or
load). Passive harmonic filters tuned to other order harmonics are available special order. Consult the
manufacturer for more information. If the CPC you are installing is equipped with an optional harmonic filter,
consult Section 7.1 of this manual for complete information regarding it’s location and operation.
Zig-Zag transformer - This option is only available on models 85 kVA and larger. Special transformers with
zigzag secondary windings for the elimination of harmonic currents are available as a special order from the
manufacturer.
Basic metering/Power management package - All CPC models may be equipped with basic metering
functions using Power Measurements Limited 6200 ION monitor. A full power management package is available
on models 85 kVA and larger. This package uses a Power Measurements ION 7500 monitor and provides
multiple functions including low voltage/phase loss/phase reversal detection and protection.
