 [Caution]
Ensure to read this manual before installing METi-2500.

Make sure this product is complete without any mechanical

damage on it.
www.Elec-Engg.com

When disconnecting or disassembling METi-2500, make sure

first to disconnect the power, current and voltage of the
product.

Make sure that the current input terminal, the secondary of the
CT, is not opened when the current is provided to the primary
of the CT.

Make sure that the setup of METi-2500 is executed in

concurrence with the systematical structure (a method of
electric connection, the primary and secondary current,
voltage and whether the PT is used or not) in order to prevent
it from displaying inaccurate information.

When connecting the voltage and current to the terminal on

the back of METi-2500, make sure that the wires and the
numbers of the terminal fit to each other. If incorrectly
connected, METi-2500 displays a sign, “E 1” on its display

Do not install METi-X near inflammable or dangerous objects.

⑤ The connection of the voltage input terminal

Connect it through V1, V2, V3 and VN. For the connecting method, refer
to Figure 4 to 9 according to each phase and wire type and input type.
The input range
Direct connection : Use for lines below a 300V phase voltage. Set a
value of ‘Pt1’ as 0 and ‘Pt2’, as a value between 110 and 300V.
Connection through PT: Select a setup value of ‘Pt1’ from the range
of 110 and 99,990V and of ‘Pt2’, from 110 and 300V.

13
 [Note]
If the voltage is supplied without phase, the status display
window of METi-2500 will display a sign, ‘E 1,’ when the
power is applied.

⑥ The connection of the current input terminal

Connect it through the terminals of C11, C12, C21, C22, C31 and C32.
For the connecting method, refer to Picture 4 to 9 according to each
www.Elec-Engg.com

phase and wiring type and input type.

The range and method of input: Connection through CT(5A rating)

[Note]
• The set value should be assigned as a ratio of the
primary to the secondary current. If the primary current
is 50A and the secondary is 5A CT, the set value will be 10.
• If the connections of current input are switched, the
status display window of METi-2500 will display a sign,
‘E 1,’ when the power is applied.

⑦ The connection of the communications terminal

Connect it in the 485(1)+, 485(1)-, the below figure represents connection
of a RS-485 communications line in multi-drops.
.
! Caution
If the RS485 communications line is a shielded cable,
connect it also to the FG terminal of METi-X.

[Note]
In the three-phase and three-wire PT connection, the B phase voltage
and current are assumed to be under a balanced load condition and
therefore, the values are metered from the voltage and current of the A
and C phases. Hence, if the B phase voltage and current is not under a
balanced condition, the unit cannot satisfy its precision standard.

 ⑥ The active energy indication mode
Indicates the values of active energy in eight digits as is shown in
figure 19. Since electric energy is a cumulative value, this unit is
employed with a value indicating system in eight digits to enhance
precision. Hence, it is enabled to indicate a value of up to 9,999,999kWh
and goes back to 0 to cumulate from there if a value exceeds its maximum
indicative value. In figure 19, the electric energy can be read as 152,
379kWh, which is being displayed even when the power is disconnected
by applying a non-volatile EEPROM.

The methods of resets of some data including effective/unavailable energy,
peak power and diagnosis information that are saved in the EEPROM are as
follows:
① Go to the desired measuring indicative window by using the UP and Down
keys.
② Press the ESC and ENTER keys simultaneously for three seconds,
referring to figure 22. As for the diagnosis information, if an error prolongs,
it cannot be reset.
③ In the E-version, the backup data is reset as same method with upper.
