7.4 Maintaining the Card Cage Air Filter

The card cage features a secondary air lter to ensure long PCB life. The card cage air

lter is located under the intake air shroud above the card cage which is located on the

right side of the power module assembly in the upper cabinet.

Use the following instructions to access the secondary air lter and refer to Figure 7-3.

1. Remove the air intake shroud above the card cage. This will expose the air lter.

2. Remove the four screws on the card cage air lter.

3. Clean the lter with compressed air.

4. Once the lter is cleaned, replace the lter and shroud.

If the lter needs to be replaced, call PV Powered Technical Support at 1-877-312-3832,

7.5 Faults and Warnings

The display screen is the primary indicator of a possible problem with the inverter. If a

fault has occurred the inverter will cease power production until the fault is cleared. A

fault may be a latching or non-latching fault. A non-latching fault will be automatically

cleared if the fault condition is resolved and the inverter will restart automatically after

completing its startup sequence. A latching fault requires manual intervention to restart

the inverter.

If the inverter has faulted, the display screen will show the corresponding fault

information in a series of three or more screens.

• The rst screen – displays the fault code(s)

• The second screen – displays a text description of the fault(s).

• The third screen – displays technical support contact information.
