●Use the external devices to function the emergency stop and interlock circuit.
●Connect the wires or connectors securely. The loose connection might cause abnormal
exothermic heat or smoke generation.
●Do not allow foreign matters such as liquid, flammable materials, metals to go into the
inside of the product. It might cause exothermic heat or smoke generation.
●Do not undertake construction (such as connection and disconnection) while the power
supply is on.
●Never remove the terminal block under applying current to load.
It might cause electric shock or CT breakdown.
●Do not use at secondary side circuit of inverter. It might cause exothermic heat or
damage.

Please connect a breaker or a fuse to the power supply and voltage input part for safety reasons and to
protect the device.
･Recommended breaker: 3 to 15A
･Recommended fuse : Time-lag fuse rated current 2A
Grounding the secondary side of VT (Voltage transformer) and CT (Current transformer) is not
necessary with low-voltage circuit.
*When using several CTs, set each CT approximately 1m apart. If the two CTs are set too close each
other, it may not measure accurately due to magnetic field interference.
◆When measuring a load with rated input voltage
Single-phase two-wire system
*One CT is needed to measure single-phase two-wire system.
*2 CTs are needed to measure 2-circuit and 3 CTs are needed to measure 3-circuit.
*To measure 2-circuit, wire 3 and 4. To measure 3-circuit, wire 3 and 4 and 5.
Single-phase three-wire/Three-phase three-wire
*2 CTs are needed to measure single-phase three-wire system, three-phase three-wire system.

KW9M Eco-POWER METER

Three-phase four-wire system
*3 CTs are needed to measure three-phase four-wire system.
◆When measuring a load with exceed input voltage
Voltage transformer (VT) is needed when you measure a load with over input voltage.
Use a VT, those secondary voltage rating is 110V.
Grounding the secondary side of VT and CT is not necessary with low-voltage circuit.

3.3 How to attach the Current Transformer (CT)
・Use CT that the secondary side current is 5A or 1A, the rated burden 0.5VA or more.
・One CT is needed for 1 unit when measuring 1P2W (2 CTs for 2-circuit, 3CTs for 3-circuit). Two CTs
are needed when measuring 1P3W/3P3W. Three CTs are needed when measuring 3P4W.
Using all CTs for one unit should be the same.
・Use the applicable wire, or it might cause a breakdown, burnout or electric shock.
・When connecting CT, connect the secondary side to the terminal of the main unit first, and after that
wire the primary side to a load electric wire. Incorrect order might cause an electric shock or break CT.
・The CT has polarity. Wire correctly according to the K and L marks. Wrong direction can’t measure
correctly.
･If there is some distortion by harmonic or waveform, it may not measure correctly.
Please check with the actual system before adopts it.
・Separate the wiring (strong electric part) of the measured voltage input terminal (operating power
supply terminal) from the CT cable. It may not satisfy the accuracy due to noise.
DANGER
●Never open the secondary circuit of CT under applying current to load.
●Never remove the terminal block under applying current to load.
Will cause electric shock or breakdown CT

◆How to connect CT
(1) Power off the measured devices.
(2) Install applicable CT.
(3) Remove terminal block of KW9M.
(4) Connect CT to the terminal block.
(5) Insert terminal stand surely.
(6) After confirm all wiring correct, turn on the power of the load and KW9M.
(Connection example)
◆How to set the parameters for CT
(1) Select CT type (CT-T) according to the using CT.
(Select ‘5A’ if secondary side current of using CT is 5A. Select ‘1A’ if secondary side current
of using CT is 1A.)
(2) Set the primary current of measured CT at primary side current of CT setting mode (CT-1).
< ex > If the measured CT is 400A/1A or 400A/5A, set to”400”.
(3) Connect CT according to the CT direction, power side (K) to load side (L).

3.4 RS485 Communication
・When using shielded cable for the RS485 transmission line, ground one end.
Use a class D dedicated earth for grounding. Do not share a ground with other earth lines. (Fig. 1)
・For terminal stations of both side including the upper device, termination resistors should be
connected. KW9M Eco-POWER METER doesn’t have any built-in termination resistors.
Connect 120Ω, 1/2W or more termination resistor between [A+] and [B-] of Eco-POWER METER that
is connected the end of RS485 transmission line. The RS485 transmission line shielded cable should
be grounded at the end KW9M Eco-POWER METER. (Fig. 1)
・Be sure to connect with daisy chain the RS485 transmission line between each unit.
Do not use a splitter. (Fig. 2)
・To avoid noise, separate the transmission line from high-voltage line (power supply, voltage line).
