1.2) Three-phase measurement: Three-phase group device setup with three single-phase modules

Three-phase measurement is possible by installing three single-phase modules in the three-phase 3-wire or

three-phase 4-wire connection and setting the group device. Refer to "Chapter 4>Setup Mode>Accura 2350-

1P Group Device Setup" for group device setup.

Single-phase single-hole three-module group device for 3-phase 4-wire/3-phase 3-wire

1.3) Three-phase measurement: Three-phase group device setup with two single-phase modules

Three-phase measurement is possible by installing two single-phase modules in the three-phase 3-wire

connection and setting the group device. Refer to "Chapter 4>Setup Mode>Accura 2350-1P Group Device

Setup" for group device setup.
