This manual will use V1, V2 and V3 to represent the three-phase conductors, which is the same
as Va, Vb and Vc in other literature.

Auxiliary Power Supply:
The AcuRev 1312 power meter requires an AC supply of 100-415V at 60Hz for operation. In nor -
mal operation, the power consumption of the meter is less than 1 Watt so the meter can be
powered by either an independent power supply or it can obtained from the circuit under test.
It is suggested that if the power is obtained from a source with large power fluctuation then a
voltage stabilizer be used. A fuse (typically 1A/250Vac) is also suggested to be used when con-
necting the power supply to the meter.
The typical auxiliary power supply wiring is as follows:
1 A, B, S RS-485 Communication Terminals;
2 P1, P2 Pulse Output
3 L, N Auxiliary Power
4 V1, V2, V3, Vn Voltage Input Terminals
5 I11, I12, I21, I22, I31, I32, I41, I42 Current Input Terminals
6 R1, R2 Relay Output Terminals.
