Caution for Wiring

1) Terminal fastening torque should be 0.5 to 0.6N･m. In case of using a crimping terminal, use it with insulating sleeve applic able to M3 screw.

2) This has no built-in power switch, circuit breaker for power supply part. To protect the device, it is necessary to install power switch and circuit breaker in the power supply circuit.

And this has no built-in power switch, circuit brea ker or fuse for measured voltage input parts. Therefore it is necessary to install them in the circu it near this unit.

3) We recommend a wire with the cross s ect ion of 0.75 to 1.25mm

for power supply line and measur ed

voltage input line.

4) Use flame-resistant cable for each wiring.

KW1M-H Eco-POWER METER

3.2 Wiring Diagrams

Please connect a breaker (3 to 15A) to the voltage input part for safety reasons and to protect the device. Grounding the secondary side of VT (Voltage transformer) and CT (Current transformer) is not necessary with low-voltage circuit.

◆When measuring a load with rated input voltage (100-200V system/ 400V system)

Single-phase two-wire system *One current transformer (CT) is required.

Do not wire ⑥ ⑦ terminals. They are connected internal. Single-phase three-wire / Three-phase three-wire system *Two current transformers are required.

Three-phase four-wire system *Three current transfor mers are required.

Do not wire ⑦ terminal. It is connected internal.

KW1M-H Eco-POWER METER

Single-phase, three-wire system Three-phase, three-wire system

◆When measuring a load with exceed input voltage

Voltage transformer (VT) is needed when you measure a load with over rated input voltage ( 440V). Use VT, those secondary r at ing i s 110V. Grounding the secondary side of VT and CT is not necessary with low-voltage circuit.

Single-phase two-wire system

Three-phase, four-wire sy st em

◆Using the clock correcti on function by frequency of the measured voltage

It corrects the clock by using the measured voltage frequency input to P1-P0 as a reference frequency. When P1 -P0 terminals are not connected or it set OFF for clock correction function, it doesn’t correct the clock.

3.3 How to attach the Current Transformer (CT)

・One current transformer (CT) is needed to measure 1P2W system. Two CTs are needed to measure a

1P3W/3P3W system. Three CTs are needed to measure a 3P4W system. Using all CT should be the same.

・Check beforehand that the t hickness of the electric wire is s ma ller than the through-ho le of the CT. ・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 ca use an electric shock or brea k C T.

・The CT has polarity. Wire correctly according to the K and L m arks.

Wrong directi on c an’t measure correctly.

・When closing clam p-on type CT, check that there is no foreign materials on the divided face. And

make sure it is closed securely once the wire is in place; if not the measurement value will be not

accurate.

・When CT’s cable is extended, it is possible to extend up to about 10m with the cable of AWG#22 or

more cross section under the environment without noise at all. Please use the thick cable as much as possible. *Please check beforehand with the actual s ystem in case of extending the cable.

･If there is some distortion by harmonic or waveform, it may not mea sur e correctly. Please check with

the actual system before adopting it.

・Separate the wiring (strong electric part) of the measured voltage input terminal (operating power

supply terminal) from the CT c able. It may not satisfy the accuracy due to noise.

・Only same color housing of cable and connector of CT can be co nnected.

That of different color (blu e and white) can't be connected.

◇To connect CT with secondary side current 5A

How to set for measuring by combination with CT (secondary side current 5A)

(1) Select 5A at CT type sett ing mode (CT-T). (2) Set the primary current of measured CT (secondary side current 5A) at primary side current of

CT setting mode (CT-1). <ex> If the measured CT is 400A/5A, set to’400’. (3) Clamp the dedicated CT for 5A, which is connected to the main unit first, to secondary side of

3.4 For input connection

・Contact input

Use highly reliable metal plated contacts. Since the contact’s bounce time leads directly to error in the count value, use contacts with as short a bounce time as possible. In general, select 30Hz for max. counting speed.

・Non-contact input (Transistor input)

CBO

Use transistors with a residual voltage of less than 1.5V when the transistor is ON.

＊Short-circuit impedance should be less than 1 kΩ.

(When the impedance i s 0Ω, drain current is approx. 7m A. )

Open-circuit impedance should be more than 100kΩ.

・Input wiring

Please wire up to 10m by using a shielded wire or a metal lic electric wire tube indiv idually. If it is long, it may not work correct ly due to floating capacitance of wire.

(Note)

Operating power supply input part and measured voltage input are not insulated to pulse input parts. So the input equipment must have the power supply transformer in which the secondary side is not grounded with the primary and secondary sides insulated, in order to prevent interference of the power supply circuit when connecting the external input circuit. Be sure not to use an auto-transformer.
