Step-by-Step Basic Installation

Ensure Adequate Ventilation

Step 2: To summarize the caution messages—you will need to find a solid, non-flamma-

2 ble, 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

3a 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. The inverter housing comes from the factory with a snap-in cover on the top of its housing. Ensure it is in place at this time (also to be removed later, unless the installation must have a NEMA rating).

Please observe this checklist while mounting the inverter:

Top cover installed

Ventilation holes

(both sides)

1.The ambient temperature must be in the range of -10 to 40°C. If the range will be up to 50°C, you will need to set the carrier frequency to 2.1 kHz or less and derate the output current to 80% or less. Chapter 3 covers how to change parameters such as the carrier frequency. Remember to remove the top cover (unless the installation is to have a NEMA rating)!

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