Input open-phase protection (PHASE)
Three-phase input power supply may operate normally even when one of the phase
is open. However, operating the PAT in an open-phase condition puts stress on the
PAT and may cause a malfunction.
To prevent a malfunction from abnormal input, this function is activated when one
or more phase is open among the three-phase input, and the turns off.
• When the PAT operates in the single-phase input mode, this function (Input
open-phase protection (PHASE), becomes invalid.

Shutdown (SD)
p. 5-19
Shutdown is not activated as a result of the PAT detecting an error. It is a function
used to turn off the output by applying an external signal to the J1 connector on the
rear panel when an abnormal condition occurs.
p. 4-20
You can select whether to trip the breaker (CF27: ON/OFF) when the shutdown
signal is applied.
