1.3 Product Features
Multifunction, high accuracy
AcuRev 1310 series meter has data collection and management for energy and multi-pa-
rameters measurement. It also features demand measurement and event logging.
The measurement accuracy of energy, power, voltage, and current is 0.5%.
Small size, convenient installation
The appearance and dimension of the AcuRev 1310 series meter is designed in accor-
dance with the IEC 35mm DIN standard.
Clear Display
The AcuRev 1310 series features a clear display to provide visibility in all environments. All
measurement parameters can be found and easily accessed through the display. The LCD
display has backlight support that can aid users in weak lighting environments.
Safety
AcuRev 1310 series product has both an electronic and physical sealing function. It is de-
signed is such a way that it cannot be opened without leaving signs of tampering. Users
cannot change the parameters through the display when the electronic sealing is closed,
and important parameters cannot be changed through communication, thus preventing
data or con󳆂gurations from being altered.

Before Installation
The installation must be performed by quali󳆂ed, competent accredited professionals who has
received formal training and has experience with high voltage and current devices. Appropriate
safety wear (gloves, glasses, arc 󳆃ush suit, etc.) is mandatory to ensure safe installation.
During normal meter operation, caution should be used when handling the following as high volt-
age may be present:
• Terminal Blocks
• Current/Potential Transformer leads and the related circuits
• All primary and secondary circuits may contain lethal current and voltage.
• Contact with current channels must be avoided.
✓The power meter and I/O modules cannot be installed on the primary side of transformers or
where VA has limitations. The power meter can be only installed on the secondary side. Avoid
contact with meter terminals after the completion of installation.
✓Do not supply input voltage above the rated maximum limit of the power meter and devices
connected to it. Before energizing the meter, please refer to the meters label and speci󳆂ca-
tions.
✓Do not perform high voltage test or insulation experiments to output, input or communication
terminals.
✓The use of shorting blocks and fuses are recommended. Current transformers need to be
grounded (5A/1A).
✓Use dry cloth to wipe the meter.
This chapter mainly describes the installation process of the AcuRev 1310 series meter, which is a
very important step in using the meter correctly. This chapter provides information and diagrams
about how to install the meter. Before installing the meter, please read through this section 󳆂rst.

2.2 Installation Methods
Environmental
Before installation, please check the environment, temperature, and
humidity to ensure the AcuRev 1310 series meter is being placed in an
environment that are within temperature and humidity speci󳆂cations.
Temperature
AcuRev 1310 operating temperature is -25 ~ 75° C. Exceeding this temperature range will cause
damage to the meter and will a󳆁ect the accuracy and functionality. Please note this can in󳆃u-
ence the meters life negatively if the meter operates in extremely high or extremely low tem-
peratures. AcuRev 1310 storage temperature range is 40~85° C.
Humidity
5% to 95% non-condensing.
Location
AcuRev 1310 series meter should be installed in a dry and dust free environment. Avoid expos-
ing the meter to excessive heat, radiation and high electrical noise sources.
Installation Steps:
This product is DIN railed mounted and 󳆂ts on a standard 35mm rail.
1. To install the meter on the rail insert the top of the rail into the groove on the back of the me-
ter. Pull the metal clips back and slide the rail across the groove of the meter.

of the environment must
accord with the require-
ment of AcuRev 1310,
Otherwise it may cause
the meter damaged.

2.3 Wiring
The terminals of the AcuRev 1310 series can be accessed by 󳆂rst removing the terminal covers
on the meter.
1. To open the terminal cover, remove the seal if applicable, and then unscrew the sealing
screws and lift the cover upwards to remove.

2. To attach the bottom terminal cover back onto the meter, place the left side of the cover
down into the groove 󳆂rst and then press down onto the right side, see Figure 2-6. When in-
stalled correctly, you will hear a clicking sound. To attach the top cover place the right side of
the cover down into the groove and press down onto the left side.

2.3.2 Auxiliary Power Supply:
The AcuRev 1310 series meter requires a power supply of 100 ~ 415 Vac at 50/60 Hz. For use of
other power supply voltage selections please contact the manufacturer. The meter typically has
small power consumption (less than 1W) so the power supply can be an independent power
supply, or can also be obtained from the circuit under test.
It is suggested that under the condition that the power voltage 󳆃uctuation is large, to use a volt-
age stabilizer. The power supply terminals respectively are: L, N.

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 con󳆂rm 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 con󳆂guration 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 con󳆂guration 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:

2.3.4 Current Input:
Current Transformers (CTs) are required in most applications. The AcuRev 1310 series meter
supports four CT input types, 5A/1A, 333mV, Rogowski coil (RCT) and mA (80/100/200). CTs must
be used if the systems rated current is over 5A. The CT should be selected to maintain revenue
grade accuracy of the system. The distance between CT and the meter should be as short as
possible as the length of the CT leads will have an e󳆁ect on the accuracy.
The meter requires AWG22-14 as the wire size to the current input terminals.
Note: The secondary side of the CT should not be open circuit in any circumstance when the
power is on. There should not be any fuse or switch in the CT loop. One end of the CT loop
should be connected to the ground when 5A/1A output CTs.
When using mV, RCT and mA CT's the secondary leads must not be grounded.
Vn Connection
Vn is the reference point of the AcuRev 1310 series meter voltage input. Low wire resistance
helps improve the measurement accuracy. Di󳆁erent system wiring modes require di󳆁erent Vn
connection methods. Please refer to the wiring diagram section for more details.
AcuRev 1310 series meter supports di󳆁erent wiring con󳆂gurations for both three phase and sin-
gle phase systems. Please read this section carefully before choosing the suitable wiring meth-
od for your power system.
In the AcuRev 1310 series meter please make sure that the wiring connection mode and the cor-
responding practical application in engineering are correct to ensure the measurement accura-
cy of meter. Here are some of the common installation methods, their respective diagrams and
meter con󳆂gurations for the AcuRev 1310 series meter.
