• When the phase input mode is changed to the single-phase input mode from the
three-phase input mode, the setting value of the output current and the
overcurrent protection (OCP) is limited to 75 % of the rated value of output
current and the overcurrent protection of the three-phase input mode.
Breaker trip function when the OVP or OCP is activated
p. 4-20
You can select whether to trip the breaker (CF28: ON/OFF) when the OVP or OCP
function activates.
OVP and OCP trip point settings
The OVP operates on the output terminal voltage. If you want to activate the
function on the voltage across the load, set the OVP trip point by considering the
voltage drop in the load cable.

While vie w ing the panel display, t u rn the VOLTAGE knob to set the
OVP trip point or the CURRE N T knob to set the OCP trip point.
If the voltage setting is limited in the CONFIG settings (CF29: ON), the OVP trip
point cannot be set lower than the present preset output voltage.
If the current setting is limited in the CONFIG settings (CF30: ON), the OCP trip point
cannot be set lower than the present preset output current.
Setting limit function
• When the phase input mode is changed to the single-phase input mode from the
three-phase input mode, the setting value of the output current and the
overcurrent protection (OCP) is limited to 75 % of the rated value of output
current and the overcurrent protection of the three-phase input mode.
The PAT allows limits to be placed on the voltage and current settings through
CONFIG settings so that the overvoltage protection (OVP trip point) and the
overcurrent protection (OCP trip point) settings are not exceeded.
This function prevents the output from being turned off when you accidentally set
the voltage or current to a value exceeding the OVP or OCP when the output is on.
If you select to limit the voltage setting (CF29: ON), the output voltage can no
longer be set to a value to approximately 95% of the OVP trip point. In addition, the
OVP trip point can no longer be set to a value less than the preset output voltage.
If you select to limit the current setting (CF30: ON), the output current can no
longer be set to a value to approximately 95% of the OCP trip point. In addition, the
OCP trip point can no longer be set to a value less than the preset output current.
