2.3 Setting the Voltage Range
Hold down for at
least 3 seconds.
Measured Value screen
Startup screen Voltage Range screen

The PR300 shows the Startup
screen for about 5 seconds,
then the Measured Value
screen appears.
When proceeding to set the
phase and wire system, press
or to show the
Phase and Wire System
screen, with this screen
(figure in the upper-left
corner) shown as is. After
showing the Phase and Wire
System screen, start from
step
6 in Section 2.2, “Setting
the Phase and Wire System.”
Current value
The setpoint is confirmed and the PR300
returns to the Voltage Range screen.
The voltage range thus set is shown as
the current value.
Setting completed.
NOTE
If you change the voltage range, all parameters other than those related to RS-485 and Ethernet
communications are initialized (to factory-set values).Change the voltage range before setting
parameters such as the VT and CT ratios.

NOTE
●
The voltage range of single-phase three-wire system is fixed at 300V (between P0 and P1, P0 and
P2). The voltage range cannot be selected.
● Select the voltage range of three-phase four-wire system by the phase voltage (between P0 and P1,
P0 and P2, P0 and P3).
