1. FLA = FULL LOAD AMPS

2. Amperage requirements are based on the rated max FLA current of each component in the unit. The rated max FLA current of the unit is
not the sum total of all components, but is the total of the components which operate during maximum electrical load conditions.

3. The values in the table are for power demand of the unit only.

4. Units are 3-phase, 50-cycle.

5. Consult factory engineering department for electrical requirements of units with variations not listed above.
