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 lowimpedance 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.
Section 3 - Product Overview 3.2 Standard Features These include a “power on “ LED, TVSS Fault LEDs (one per phase), a lockout/tagout provision for the front panel input circuit breaker, safety interlocks, casters, and leveling feet. In addition, the CPC offers a range of options as described below. 3.3 Optional Features Input line cord - This option is available on models 45 kVA and smaller. Output receptacles - This option is available on all models.
Section 3 - Product Overview complete monitoring of three phase voltages, currents, phase angles, power factor, demand, energy usage, event logs and more. If the CPC is equipped with the power management option, documentation prepared by Power Measurements Limited will accompany this manual. The table below illustrates a matrix of standard equipment and options for each model of GPI Series 2000.
Section 4 - Preparation IMPORTANT ! Each unit is fully inspected and tested prior to leaving the factory. CPC series products are packed carefully in approved shipping crates. However, since we cannot control handling during shipping, damage in transit is possible. Please retain all packing materials until the power conditioner is installed and operating satisfactorily. If damage to the shipping container is evident, you may file a claim with the shipper.
Section 4 - Preparation Step 2 - A packing block assembly rests on top of the power conditioner to secure it tightly inside the packing crate. Remove the packing block assembly by removing the screws that are driven through the crate front and back panels into the ends of the wooden struts. The packing block may now be removed and set to one side. Step 3 - The front and back panels of the packing crate should be removed next.

Section 5 - Installation 5.1 Location For best performance, the CPC series should be installed within fifty (50) wire feet maximum of the protected load. Refer to the dimensional information shown in the specifications sheet accompanying this document. Allow six inches of free space on all sides of the CPC series to provide for proper air circulation. The unit is designed to operate at high efficiency and is convection cooled.
Section 5 - Installation 5.3 Outer Panel Removal The side panels, the back panel, the top panel and the front panel have all been designed for easy removal prior to installation. The side panels must be removed first. Turn the quarter turn fasteners counterclockwise and remove the side panels. A bonding strap is attached to the bottom of each side panel with a hand fastener and lock-washer. The bonding strap electrically grounds the side panel to the frame during normal operation.
Section 5 - Installation 5.5.2 Programmable Circuit Breakers Before beginning installation, check the tag on the circuit breaker. The power conditioner has been manufactured and shipped according to the input voltage specified at the time the order was placed. If the input voltage information shown on the tag does not match the voltage available at your site, check the tag to determine the transformer primary configuration and circuit breaker type.
Section 5 - Installation Transformers are designed to meet a variety of requirements. Some locations (Europe, for example) have standardized on a single input voltage. In other cases customers may specify multiple input voltages to accommodate the variety of voltages commonly found in the United States. The CPC series conditioner can accommodate either style of transformer - single voltage or multiple voltage primary. The conditioner is a "delta-wye" system.
Section 5 - Installation 5.6.2 Output Voltage Fine Adjustment The transformer secondary of the power conditioners is a 5 wire Wye configuration (three phase conductors, one neutral and one safety ground). Output voltage can be adjusted plus-or-minus five percent ( + 5%) (as shown in Figure H to the right) to accommodate site-specific voltage differences . This is accomplished by moving the output lugs and connections on the transformer secondary. Consult the information found in Section 10.
Section 5 - Installation Specific locations for connecting the input and output safety ground conductors are discussed in Sections 5.9 and 5.10 that follow. These sections cover the information necessary to connect electrical wiring to both the main and to the load. Please review both sections carefully before beginning the actual electrical installation. A sophisticated electronic system will benefit greatly when all parts of the system and all system peripherals are powered from a single power source.
Section 5 - Installation 5.9 Input Power Connections The three-phase input connection is made at the lugs marked L1, L2, and L3 directly on the main circuit breaker shown in Figure K to the right. The safety ground connection is made at the dual lug marked “PE” on the rear of the panel immediately behind the main circuit breaker shown in Figure L to the right. Locate all connection points prior to committing to the conductor lengths.
Section 6 - Operation 6.1 Restoring For Service When wiring connections have been completed (or after maintenance or repair operations are finished) it will be necessary to perform several tasks before the power conditioner can be put into service. Take these steps in the following order: 1. Verify that all electrical connections are tight. 2. Verify that the enclosure, transformer and all other internal components are free of metal shavings, debris, and installation/maintenance tools. 3.
Section 6 - Operation (NOTE: Under "no load" conditions, the transformer in the power conditioner will "step up" the output voltage a few percent. This design characteristic compensates for losses within the transformer once actual load is applied. As a result, an output voltage that is slightly higher than the nominal input voltage is normal under unloaded conditions.) (NOTE: For further information on Power Measurements Limited meters or monitors, consult the separate owner’s manual.
Section 7 - Options 7.1 Passive Harmonic Filter The passive harmonic filter package is located below the transformer secondary on the left side of the power conditioner. See Figure N to the left. This circuit is bi-directional. It will mitigate odd order harmonic currents originating from the load or the facility.
Section 7 - Options 7.4 Phase Loss/Low Voltage Detection and Protection When equipped with the power management option, the 7500 ION monitor also provides: 1. Protection from the loss of one or more input phases 2. Protection for a low-voltage condition occurring on one or more phases (Protection from a high-voltage conditions is also optionally available) Should a phase loss or low voltage occur, the 7500 ION will “shunt” trip the power conditioner breaker within 50 msec. of the occurrence.
Section 7 - Options 7.7 SEMI S2-0200 Certification For use in semiconductor fabrication applications, the manufacturer offers a version of the power conditioner that incorporates special modifications of the basic product family that are required for the power conditioner to meet the safety requirements of the Semiconductor Equipment and Materials International (SEMI) safety standard S20200.
Section 7 - Options activated by the closure of an interlock switch or EMO button, provides a DC voltage to the over-voltage shunt trip coil of the input circuit breaker. In the standard EMO design, the DC voltage is derived via a full wave bridge rectifier powered from a 24 volt AC tap on the main transformer secondary winding. For SEMI S2-0200 approval, the EMO functions differently from the standard EMO. The SEMI S2-0200 EMO operates as a normally closed (N.C.
Section 8 - Troubleshooting/Maintenance 8.1 Conditions Requiring Troubleshooting Four conditions may occur, which require operators or service personnel to troubleshoot the function of the power conditioner. Each may be individually evaluated. These four occurrences include: 1. 2. 3. 4.
Section 8 - Troubleshooting/Maintenance Prior to performing maintenance of any kind, lockout and tagout the electrical power at both the facility source and the input circuit breaker. Under these conditions, entering the equipment enclosure will be classified as a Type 1 task under SEMI S2-0200 guidelines. Power must be locked out and tagged out at both locations prior to entering the enclosure for maintenance purposes. 8.1.2.
Section 8 - Troubleshooting/Maintenance 8.1.4 Harmonic Filter Circuit Breaker Trips Out If equipped with a harmonic filter option, the power conditioner will incorporate a passive harmonic filter. One characteristic of such filters is that they tend to “sink” harmonics regardless of whether the source is the load or the facility. In some circumstances, it is possible that the load and the facility together may require more reactive current than the filter is rated to provide.
