Please avoid installing the inverter in environments where lint, cotton fibers, damp dust, or dirt may obstruct the heat sink. If usage in such environments is necessary, install the inverter in a cabinet to protect it from damage. Prevent the ingress of lint and similar particles.

Precautions for Temporary Storage
(1) Do not place directly on the floor.
(2) If the surrounding atmospheric conditions do not meet the above storage requirements, seal the product in polyethylene cloth or similar packaging for storage.
(3) If moisture exposure is a concern, please include a desiccant (such as silica gel) and seal with polyethylene cloth or similar material.

Precautions for Long-Term Storage
• If the product is stored for more than 3 months, the surrounding temperature should be maintained between -10 and +30℃ (14 to 86℉). This is to prevent degradation of the electrolytic capacitors within the inverter.
• The packaging must be sealed to protect the inverter from moisture. Desiccants (such as silica gel) should be included within the packaging to maintain a relative humidity of less than 70%.
• If the inverter is stored for over one year, the performance of the electrolytic capacitors may decline. At least once a year, connect the inverter to power and operate it for 30 to 60 minutes.
