Xantrex Technology PV-225208 Section Preventative Maintenance, Inductor Enclosure

SECTION 6

PREVENTATIVE MAINTENANCE

Mechanical electrical connections will loosen over time. This is caused primarily by thermal cycling during normal operation.As connections loosen, electrical impedance will increase at the connection, eventually leading to fire and component damage. It is critical to check all electrical connections every six months.

Inductor Enclosure

Access the inductor enclosure and remove any accumulated dirt and debris. Vacuum enclosure whenever dust or dirt is present.

ISOLATION PROCEDURE

The following procedure should be followed to de-energize the PV-225208 for maintenance:

WARNING

The terminals of the PV input may be energized if the arrays are energized. In addition, allow 5 minutes for all capacitors within the enclosure to discharge af- ter shutting down the PV-225208.

1.Turn the on/off switch to the off position.

2.Open the DC interface (PV array) disconnect switch.

3.Open the AC interface disconnect switch.

4.Open the isolation transformer circuit breaker.

5.Install lockout devices on the isolation transformer circuit breaker and PV disconnect switch.

TURN-ON PROCEDURE

Refer to Section 3 for a detailed first-time turn on procedure.

1.Remove any lockout devices from the isolation transformer circuit breaker and PV disconnect switch.

2.Close the isolation transformer circuit breaker.

3.Close the AC interface disconnect switch.

4.Close the DC interface (PV array) disconnect switch.

5.Turn the on/off switch to the on position.

After a 15 second initialization period and a 5 minute wake up period, the PV-225208 will automatically begin power tracking, given the PV voltage is greater than the PV start voltage setpoint.
