Installation Method
Environment
Make sure meter is installed in a dry and dust free environment. Avoid placing meter
near to heat, radiation and strong electrical interference sources. Meter's working
temperature range is from -25°C to 70°C.
Meter can be installed into an ANSI C39.1 (4'' round) or an IEC 92mm DIN(square)
form.
Installation Steps
1. Meter Installation
(1) Cut a square or a round hole on the panel. Units: mm(inches)

2. Extend module Installation
(1) The extend module could be installed from the bottom of the meter.
(2) The extend module is fixed on the meter by the screw.
Note: The display meter and the remote display unit have the same installation
method. The DIN rail meter have a quite other installation method, it must be
installed on the 35mm rail. You can references the others DIN rail meters for the
details installation method.

(3) Install the clips to the meter from backside and push the clips tightly so that the
meter is fixed on the panel.

Communication and Digital Output
Note: Model Acuvim-AL has no digital output and communication terminal strips,
Model Acuvim-BL/CL/DL/EL/KL share the same strips. When the Acuvim-BL is
selected, the strips is used as DO. When Acuvim-CL/DL/EL/KL would be selected, the
strips are used for communication.

Extend module
The meter has 2 current input options available for dierent applications.
1. Standard: 5Aac
2. Optional: 1Aac
Ground Terminal Connection
Before setting up the meter's wiring, please connect the meter's ground terminal and
the switch gear's ground terminal together.
Auxiliary Power
The meter has 2 auxiliary power supply options available for dierent applications
(aux. power supply terminals are 11, 12, 13).
1. Universal (standard): 100~415Vac, 50/60Hz; 100~300Vdc
2. Low Voltage DC Power: 20~60Vdc
Please make sure the right type before powering up the meter.

Wiring Diagram
The following shows two typical wiring input configurations:
Please refer to Acuvim-L user's manual section 2.3 for other wiring configuration
details.
Settings Mode
Meter Settings
Press V/A and H together to enter the meter setting screen. Press “H” to move the
flashing cursor to the right, press “P” to decrease the number by 1 once a time, press
“E” to increase the number by 1 once a time, press “V/A” to accept the change and
move to the next screen. Before accessing the parameter setting mode, a four digit
password is required every time. The default password is 0000. The below fig would
show the pass page.

In the basic parameter setting mode, by setting the correct meter address,
communication baud rate and parity (Acuvim-CL/DL/EL/KL only), we can
engage in normal communication. The connection mode by setting the voltage,
current connection mode, the voltage transformation ratio PT1, PT2, the voltage
transformation ratio CT1, CT2 in order to achieve accurate measurement of the basic
amount. Please refer to the specific setting "Acuvim-L User's Manual".
Communication
The meter has a standard RS485 communication port when the meter type is
Acuvim-CL/DL/EL/KL. The meter supports dual communication which means the
RS485 serial communication can be used together withother RS-485 in extend
module when the Acuvim-CL/DL/EL selected.
Serial communication terminals are A, B, S (14, 15, 16). A is dierential signal+, B is
dierential signal – and S is shield. Up to 32 devices can be connectedon a RS485
bus. The overall length of the bus cannot exceed 1200m (4000ft). When multiple
meters are connected serially on the same RS485 bus, each meter shall have a
different device address. Enter basic parameter setting page to set the device
address. This address can be any integer between 1 and 247.
Baud rate can be selected from one of the six values: 1200, 2400, 4800, 9600, 19200
and 38400 bps. Parity needs to set one of the followings: Odd, Even, None1 (stop bit 1),
None2 (stop bit 2).
I/O Options (if equipped)
Two types of IO modules with dierent IO combinations are available.
IO parameters can be set or viewed either from the meter front or through
communication using utility software. Please refer to Acuvim-L user's manual for
operation details.
Digital Input (DI)
DI is a dry point, no external power supply. DI can be used as pulse counter, to
monitor switch status or to monitor sequence of events.

Time of Use (Acuvim-EL only)
Acuvim-EL has time of use (TOU) function and can be set via meter’s utility soware
through communication. User can assign up to 4 dierent taris (sharp, peak, valley
and normal), 12 TOU seasons, 14 TOU schedules and 14 TOU segments according to
billing requirements. The meter will calculate and accumulate energy to dierent
taris according to the meter’s internal clock timing and TOU settings. Please refer
to Acuvim-L user’s manual for more details.
DIN Rail Installation
Except the LCD display and the front panel control keys, the meter with DIN rail
mount option includes the same functions as the panel mount version. The default
device address, the default baud rate and the default check of the DIN rail meter are
1, 9600 and NON1. Those default values will always be used for the first minute aer
the meter is powered on. The device address, the baud rate and the default check of
the meter will change to the user defined values aer the first minute.

Digital Output(DO)
Two modes available: alarm output, energy pulse output. two modes could be used
independently in one module. The alarming mode and energy pulse mode can be
set from the utility soware or from the meter front soware.
