Ensure Adequate Ventilation

Step 2: To summarize the caution messages—you will need to find a solid, non-flammable, vertical surface that is in a relatively clean and dry environment. In order to ensure enough room for air circulation around the inverter to aid in cooling, maintain the specified clearance around the inverter specified in the diagram.

CAUTION: Be sure to maintain the specified clearance area around the inverter and to provide adequate ventilation. Otherwise, the inverter may overheat and cause equipment damage or fire.

Keep Debris Out of Inverter Vents

Step 3: Before proceeding to the wiring section, it’s a good time to temporarily cover the inverter’s ventilation openings. Paper and masking tape are all that is needed. This will prevent harmful debris such as wire clippings and metal shavings from entering the inverter during installation.

Please observe this checklist while mounting the inverter:

1.The ambient temperature must be in the range of -10 to 40°C. If the range will be up to 50°C (maximum rating), you will need to refer to “Derating Curves” on page 1–11.

2.Keep any other heat-producing equipment as far away from the inverter as possible.

3.When installing the inverter in an enclosure, maintain the clearance around the inverter and verify that its ambient temperature is within speci- fication when the enclosure door is closed.

4.Do not open the main front panel door at any time during operation.
