NOTES:

1. Amperage values in the table are nominal. Tolerance is +5/-10%.

2. Voltage values are @ 60HZ.

3. All models are shipped for 208/240V three phase connections. If a 208/240V single phase connection is needed, the machine is field convertible at the terminal block. See wiring diagram AI1378.

4. On all 208V machines, the 240V heating element is being used (total KW output is reduced).

5. On VE40 three phase machines only, the heating elements are wired to be an unbalanced load.
