alternate power supply must generate
the same voltage, phase, and
frequency (Hz) as shown in Table 9 or the furnace rating plate.
Power from an alternate power supply that is non-sinusoidal may
damage the furnace electronics or cause erratic operation.
Contact the alternate power supply manufacturer for specifications
and details,
