1.7.6 Audible Noise
Less than 65 dBA per Type 2, IEC and ANSI SI.4, when measured in a 40 dBA environment at a distance of 4 feet
from any surface. At nominal ambient (+23C) and 75% load, typical audible noise is 50 dBA in the ON-LINE mode,
56 dBA in the OFF-LINE mode.
1.7.7 Cooling
Forced air. Air intake is through the front of the unit, exhaust out the sides.
1.7.8 Thermal Dissipation
Heat rejection: 602.28 BTU/Hr for each rated KW of the inverter system. This is based on an inverter efficiency of
85% at full load and does not include load dissipation.
