Before Installtion
The installation must be perfomred by qualified, competent accredited professionals
who have received formal training and have experience with high voltage and current
devices. Appropriate safety wear (gloves, glasses, arc flush suit, etc.) is mandatory to
ensure safe installation.
During normal meter operation, caution should be used when handling the following
as high voltage may be present: Terminal Blocks, Current Transformer connection
nodes, Potential Transformer connection nodes and the related circuits. All primary
and secondary circuits may contacting 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 contacting with meter terminals after the completion of installtion.
Do not input voltage above the rated maximum limit of the power meter and devices
connected to it. Before energizing the meter, please refer to the meter's label and
specications.
Do not perform high voltage test / insulation experiment to output, input or
communication terminals.
The use of shorting blocks and fuses are recommended. Current transformers need to
be grounded.
Use dry cloth to wipe the meter.
The replacement of the battery must be performed by professionals.

2.2 Installation Methods
Environmental
Before installation, please check the temperature and
humidity to ensure the AcuRev 1200 series meter is being placed
where it will not be damaged.
1. Temperature
AcuRev 1200's operating temperature range is -25~70°C.
Exceeding this temperature range will cause damage to the
meter. Please note that it will influence the meter's working life negatively if the meter
operates in extremely high or extremely low temperatures. AcuRev 1200's storage
temperature range is -40~85°C.

Note
Temperature and humidity
of the environment
must accord with the
requirement of Acurev

2. Humidity
5% to 95% non-condensing.
3. Location
AcuRev1200 series meter should be installed in a dry and dust free environment.
Avoid exposing meter to excessive heat, radiation and high electrical noise sources.
Installation Steps:
This meter is DIN rail mounted, which ts 35 mm standard rails.
1. Insert the meter groove all the way into the rail, and ip the meter case as Figure
below shows, making the meter mounted into the rail.

Wiring:
Figure 2-6 wiring
Communication:
AcuRev1200 communication utilizes RS485 port, via Modbus-RTU protocol. The
wiringterminals are A, B, S. "A" is called dierential signal"+", "B" is called dierentialsignal"-",
"S" is connected to the cupper net of the Shielded Twisted Pair(STP) in the shielding layer.
The maximum distance of STP is 1200m. The distance will be shorter if more devices are on
the same communication link or using a higher baud rate.
If the master device does not have RS485 but RS232 port, a RS232/485 converter can
be utilized. Typical RS485 network topologies include line, circle and star.
In order to improve communication quality:
1. High-quality Shielded Twisted Pair is very important, AWG22 (0.6mm2) or bolder is
recommended. Two cables should be dierent colors.
2. Pay attention to "single point earthing". It means there is only one point of the
shielding connected to ground in a single communication link.
3. Every A(+) should be connected to A(+), B(-) to B(-), or it will inuence the network,
even damage the communication interface.

12
AcuRev
1200
4. "T" type connection topology should be avoided. This means no new branches
except from the starting point.
5. Keep communication cables away as much as possible from sources of electrical
noise. When several devices are connected (daisy chain) to the same long communication
line, an anti-signal reecting resistor (typical value 120-300 ohm, 0.25W) is often used at
the end of the circuit (the last meter of the chain) if the communication quality is distorted.
6. Use RS232/RS485 or USB/RS485 converter with optical isolated output and surge
protection.
7. An infrared port is also available in the Display Module, which supports meter
reading.
