Conditioned Power Center

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. Because passive

harmonic filters have a tendency to "sink" harmonics regardless of the

source, it is necessary to protect this circuit in the event of excessive

odd order harmonic content in the facility electrical system. To

accomplish this, the power conditioner provides a circuit breaker on the

front panel. Should the facility have excessive odd order harmonics, the

circuit breaker will trip. The circuit breaker may be reset while the power conditioner is operating. Unless the

source of excessive harmonic current is located and corrected, the circuit breaker will likely trip again

immediately.

NOTE: The CPC series will operate properly and provide power conditioning even if the harmonic
mitigation breaker is tripped. The breaker may be reset with power applied to the unit. However, it will be
necessary to address the harmonic condition of the facility electrical system if breaker tripping persists.

7.2 Basic Metering

If equipped with this option, a Power Measurements Limited Series 6200 ION compact modular power meter will

be installed in the front panel adjacent to the input circuit breaker. The 6200 ION provides energy and demand

measurements, per phase voltage, current, frequency and power factor, peak current demand, THD, and other

real-time, true RMS electrical parameters. Communications capability is also available. Contact the

manufacturer of the power conditioner for more information about optional communications capabilities.

7.3 Power Management

If equipped with this option, the power conditioner will have a Power Measurements Limited Series 7500 ION

power monitor installed in the front bezel. The 7500 ION is shown in Figure X. The 7500 ION monitor provides

measurement of critical operating parameters such as voltage, current, power factor and demand. It also

provides the ability to monitor apparent power, true power, reactive power and to display vector diagrams,

harmonic currents and a wealth of other information in either alphanumeric or bar graph formats. The 7500 ION

monitor stores waveforms and event logs and makes them available to facilities or systems managers when

equipped with one of several optional communications interface cards. Optional communications interfaces

include, 10Base-T or 10Base-FL Ethernet, RS-232, RS485, or modem connections. An optical port on the front

panel is standard. Contact the manufacturer of the power conditioner for more information about optional

communications capabilities.
