1.1 Functionality
Multifunction, high accuracy
Acuvim-L series multifunction power meter is designed with the latest
microprocessor and digital signal process technology. It can measure voltage,
current, active power, reactive power, apparent power, power factor for three
phases, individual harmonics up to the 2nd or 31th order, THD, real and reactive
energy, current and demand and max/min values for real time readings.
The optional Digital Output and RS485 communication can be used for sending
energy pulse output and event alarming signals. The RS485 port also can be used
for remote meter controlling and data collection. Acuvim-L series meter delivers
exceptional metering functionality and provides a cost effective solution for
customers.
Compact and Easy to Install
Acuvim-L series meter can be installed into a standard ANSI C39.1 (4" round) or
an IEC 92mm DIN (square) slot. With the 51mm depth , the meter can be installed
in a small cabin. Installation clips are used for easy installation and removal.
Easy to use
All metering data and setting parameters can be accessed by using the front
panel keys or via the communication port. Setting parameters are stored in the
EEPROM so that content will be maintained even when the meter is powered o.
Multiple Wiring Modes
The Acuvim-L series meter can be used in high voltage, low voltage, three phase
three wires, three phase four wires and single phase systems by using dierent
wiring mode settings.

(RTU) for monitoring and controlling a SCADA system. Users can access all
measurement parameters via the optional RS485 communication port with
ModbusTM protocol. Main application areas Electric Switch Gear and Control
Panels include:
Power Distribution Automation Electric Switch Gear and Control Panels
Industrial Automation Building Automation
Energy Management Systems Marine Applications
Renewable Energy
1.3 Meter Overview
The Acuvim-L series have six standalone models: Acuvim-AL(basic model),
Acuvim-BL(basic model + 2DO), Acuvim-CL(basic model + RS485), Acuvim-

Considerations When Installing Meters
Installation of the meter must be performed by qualified personnel only, who
follow standard safety precautions through the installation procedures. Those
personnel should have appropriate training and experience with high voltage
devices. Appropriate safety gloves, safety glasses and protective clothing are
recommended.
During normal operation, dangerous voltage may flow through many parts of
the meter, including: terminals, any connected CTs (Current Transformers) and PTs
(Potential Transformers), all I/O (Inputs and Outputs) modules and their circuits. All
primary and secondary circuits can, at times, produce lethal voltages and currents.
AVOID contact with any current-carrying surfaces.
The meter and its I/O output channels are NOT designed as primary protection
devices and shall NOT be used for primary circuit protection or in an energy-limiting
capacity. The meter and its I/O output channels can only be used as secondary
protection. AVOID using the meter under situations where failure of the meter may
cause injury or death. AVOID using the meter for any application where risk of re
may occur.
All meter terminals should be inaccessible after installation.
Do NOT perform Dielectric (HIPOT) test to any inputs, outputs or communication
terminals. High voltage testing may damage electronic components of the meter.
Applying more than the maximum voltage the meter and/or its modules can
withstand will permanently damage the meter and/or its modules. Please refer to
the specications for all devices before applying voltages.

2.2 Installation Methods
Environment
Please check the environmental temperature
and humidity according to Acuvim-L’s
requirement to ensure the power meter can
work well.
1. Temperature
Operation: -25°C to 70°C Storage: -40°C to 85°C
2. Humidity
5% to 95% No condensation
3. Location
Acuvim-L power meter should be installed in a dry and dust free environment.
Avoid exposing meter to excessive heat, radiation and high electrical noise
source.
Installation steps
Acuvim-L series meter can be installed into a standard ANSI C39.1 (4” round) or
an IEC 92mm DIN (square) form. 1. Cut a square or round hole on the panel of
the switch gear. The cutting size shows as Fig.2-4.
Fig.2-4 Panel cutting
Note
Temperature and humidity
of the environment
must accord with the
requirement of acuvim-L,
Otherwise it may cause
