Phase input mode
(Single-phase input, Three-phase input)
The input power mode of the PAT (4 kW type) can be switched to either three-phase
input or the single-phase input.
Before starting the operation, confirm the status of phase input mode. To verify the
status and setting of the phase input mode, refer to the “4.7 CONFIG Settings”.
The principal of difference in specifications for the phase input mode are described
as follows.
The detailed product specifications can be referred in the “9.1 Specifications”.
