Installation and wiring
2.4 Wiring the measured voltage input
To measure voltage, wire the measured voltage input terminal.
The terminal layout of the measured voltage input terminals is as follows.
Information
• R/S/T/N may be labeled U/V/W/O or L1/L2/L3/N in some cases.
• R/N/T may be labeled U/O/W or L1/N/L2 in some cases.
To wire the voltage input terminal, loosen the 3mm screw on the terminal panel, push the wire completely into the
terminal, and fix in place with the crimping terminal.
