My company had a machine moved from one facility to another.

The machine was fully operational when it was disconnected. It operates on 220V three phase power.

When powered up at the new facility the machine will not run.

Checked incoming power with the disconnect off and there is 220 on all three legs.
Turned disconnect on and read 220 across L1, L2, & L3, as expected.
When checking to ground L1 & L2 read 220, L3 has no voltage.

What would cause this?
