additional 328ft (100m).
The inverter should be installed on an upright position to ensure
sufficient cooling effect.
Note:
• UMI-B1 UL series inverters should be installed in a clean and ventilated environment
according to enclosure classification.
• Cooling air must be clean, free from corrosive materials and electrically conductive
dust.
