SECTION 3

INSTALLATION AND INITIAL TURN-ON

The following wires for connecting the PV-30208 to external devices are not provided by Xantrex Technology: (See wiring diagram on page 3-6.)

•3-Phase 208 VAC inverter output to terminals of the 208 VAC primary side of isolation trans- former. The neutral must be left floating. Ground loops will exist when the inverter starts switching, which will cause the inverter to shut down due to phase over-currents and will result in damage to the PV-30208. Also, insure that this neutral is not bonded to the isola- tion transformer frame.

•System electrical ground to the isolation transformer chassis ground.

•Isolation transformer grid side terminals to line circuit breaker (or the AC disconnect switch if present).

•PV frame ground to PV-30208 enclosure chassis ground stud.

•PV-30208 enclosure chassis ground stud to the electrical distribution system ground.

•PV+ to the inverter enclosure terminal block TBDC+.

•PV- to the inverter enclosure terminal block TBDC-.

•PV neutral if connecting a bipolar PV array.

Install all wires listed above. Refer to the following wiring diagram and the system schematics in Section 7 for more detailed terminal locations.
