Quick Start Guide Stabiliti™ Series PCS
MAN-00114, Rev D
The bi-directional AC1 port shown in Figure 2 is configured as a 3-wire delta interface. Factory
defaults are set to support North American grid standards: operating frequency is 60 Hz; operating
voltage is 480 Vac.
Detailing 50 Hz operation is beyond the scope of this document
.
AC Connections are made to the bottom terminals designated as PHASE A, PHASE B, and
PHASE C. Note that the PCS will automatically adapt to phase rotation.
An earth grounding lug shown in the image is located just below the Phase A connector.
Ensure that the chassis/enclosure is correctly grounded by utilizing this connector for earth
ground. Contact
regarding any questions you may have regarding
available AC voltage and frequency options.
AC External Circuit Protection and Disconnect
The Stabiliti™ must be installed with external circuit protection. A 50 A 3-Phase 3-wire AC
breaker, rated at 480 Vac, is commonly used for such purposes. In some jurisdictions, this
circuit breaker may also be approved for use as a safety disconnect. However, Ideal Power
recommends that you confirm specific AC disconnect requirements with your local Authority
Having Jurisdiction (“AHJ”). Some utilities may require an external “red-handle” lockable
disconnect, in additional to the protection breaker.
