AcuRev 1310
16
DIN-Rail Power Meter
The meter requires AWG22-16 as the wires to connect the power supply.
A fuse (typical 1A/250Vac) is suggested to be used when connecting the power supply to the me-
ter.
Note: Check the power supply rating before wiring. Please confirm by reading the Power Supply
information on the silver sticker at the side of the meter.
2.3.3 Voltage Input:
The maximum input voltage for the AcuRev 1310 series meter cannot exceed 400LN/690LL VAC
RMS for three phase or 400LN VAC rms for single phase. The voltage input requires a 1A fuse.
Potential Transformer (PT) must be used for high voltage systems that are greater than the me-
ters rated voltage. The rated secondary output from the PT is typically 100-120V. Please make
sure to select an appropriate PT to maintain the measurement accuracy of the AcuRev 1310
series meter. When connecting using the WYE configuration wiring method, the PT's rated input
or primary side rated voltage should be equal to or close to the phase voltage of the system to
utilize the full range of the PT being used. When connecting using the Delta configuration wiring
method, the PT's rated input or primary side rated voltage should be equal to or close to the line
voltage of the system.
A fuse rated for 1A/600V should be used when connecting the voltage inputs to the meter.
The meter requires the wire size to be AWG22-14.
Note:
Under no circumstances should the secondary of the PT be shorted. The secondary of
the PT should be grounded at one end. Please refer to the wiring diagram section for further
details.
The typical auxiliary power wiring is as follows:
