cooling
- The inverter has a temperature controlled fan for cooling.
- The fan will start once the temperature of the hot spot inside the unit exceeds
70°C / 158°f. note: In cooler ambient temperature and/or at no/low loads, the hot spot
may not reach 70°C / 158°f and hence, the fan will be off.
- If the fan fails, or if adequate cool air change is not available, temperature of hot spot
will continue to rise and at ≥ 105°C / 221°f, AC output will be shut down. AC output
will be restored when the unit cools down sufficiently.
- Place the unit in a cool, well ventilated space that has adequate cool replacement
air (fig. 3.1).
