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. Input conductor sizes areFigure KFigure L determined by electrical code. For the convenience of the installer, the manufacturer has provided these, along with other installation information, on the specification sheets included in Section 10 of this manual. Consult the specification sheet for the conductor sizes required for the power conditioner.

5.10 Output Power Connections

The load is connected to the lugs provided on the transformer's secondary winding shown in Figure M to the right. Safety ground is connected to the Neutral/Ground bus lug. This device provides a neutral ground bond. The transformer secondary is also equipped with additional taps that allow the installer to make fine adjustments to the output voltage of plus-or-minus five percent ( + 5%) of nominal output to accommodate site-specific input voltage differences. The power conditioner is shipped with the output conductor connection lugs attached to the nominal output voltage

connection. If it is necessary to utilize the fine adjustment taps, the output conductors and the connection lugs must be moved to the appropriate tap. For detailed connection diagrams, consult Section 10.4.

IMPORTANT NOTE! If this power conditioner is equipped with the basic metering or the power management option, be sure to also move the associated current transformers to the appropriate transformer secondary tap at the same time the output lug and output conductors are moved.

5.11 Models With Optional Line Cord/Output Receptacles

CPC series models 45 kVA and smaller may be equipped with optional input line cords. CPC series models of all sizes may be equipped with optional output receptacles. If equipped with an input power cord, the installation instructions discussed in paragraphs 5.9 will not apply. If equipped with output receptacles, the installation instructions discussed in paragraph 5.10 may not apply. In all cases, it remains critical to observe all grounding practices discussed in paragraph 5.7. If equipped with both line cord and receptacles, installation is a plug and play operation. In any case be sure the site voltage matches the power conditioner configuration.
