※
The table shows the required heat dissipation rate due to heat loss for each model when installing
single units in an enclosed space.
※
For multiple units, multiply the heat dissipation rate for single units by the number of units installed.
The heat dissipation data are calculated based on each model operating under rated voltage, current,
and default carrier wave.
