1.2 CORRECT USAGE AND CONDITIONS FOR SAFETY
Installation and wiring must be performed by authorized technicians in accordance with the instructions in
the user manual. Do not commission the device before proper wiring.
Make sure the device is de-energized before connecting to the mains.
Short circuit the k-l terminals of the current transformer in another location before disconnecting the current
transformers. Failing to do so will cause dangerous high voltages in the secondary terminals of the current
transformers.
Use a dry cloth to clean the device. Do not use alcohol, thinner or any abrasive materials.
Make sure all wiring is properly made before commissioning the device.
Do not open the device. There are no serviceable parts by the user.
Keep the device away from humidity, water, vibrations and dust.
It is advisable to connect a circuit breaker or an automatic fuse between the current input of the device and
the mains (2 amps).
CAUTION!
The manufacturer does not assume any responsibility for any undesired consequences if the above measures are not
adhered to.

1.5 FOUR QUADRANT REPRESENTATION
The angle(Ø) between voltage and current provides us information about the direction of energy flow. A positive
sign for active/reactive power indicates that active/reactive power is consumed. And also a negative sign for active/
reactive power indicates that active/reactive power is generated.

NOTE:
If the signs of active and reactive power are examined, it can be defined the quadrant that MMW03-M22CH
measures.
In order to understand P and Q signs in MMW03-M22CH 110P and Ecras, instantaneous displays for P and Q
must be checked.
If active power display is seem constantly, it means active power(P) is positive. If it is blinked, it means active
power(P) is negative.
If reactive power(Q) display is seem constantly, it means reactive power(Q) is positive. If it is blinked, it means
reactive power(Q) is negative.
NOTE:
Signs of P and Q can be reached through modbus communication.
E.g.; P= +10kW, Q= +5kVAr => Quadrant-1
P= -10kW, Q= +5kVAr => Quadrant-2
P= -10kW, Q= -5kVAr => Quadrant-3
P= +10kW, Q= -5kVAr => Quadrant-4

2 INSTALLATION
2.1 PREPARING FOR INSTALLATION
DANGER!
Assembly and related connections of the product, must be implemented by authorized persons in accordance with the
instructions of user manual.
DANGER!
The device must not be put into service if the operator is not sure that all connections are correctly accomplished.
2.2 MOUNTING
MMW03-M22CH is placed vertically into the gap located in the panel. After the product is placed into the panel,
fixing brackets should be installed on the product. After that it should be fixed to the panel wall with the screws.
DANGER!
Before wiring up voltage and current ends to MMW03-M22CH, you must be sure that the power is cut.
DANGER!
The product is connected to current transformer(s). Before disconnecting current transformer leads, be sure that they are
short circuited elsewhere or connected to a parallel load which has sufficiently low impedance. Otherwise dangerously high
voltages will be induced at the current transformer leads. Same phenomena also apply for putting into service.
2.3 CONNECTION DIAGRAMS
2. 3 .1 3P-4W and 3p-3W Connections
There are two ways for connections of voltage and current. With neutral (3P-4W), without neutral (3P-3W).
3P-4W (wth neutral) 3P-3W (wthout neutral)

CAUTION!
Fi g ure 1-1 1st item, displays current and voltage phase position are On/Off. If a current or voltage phase seems incomplete
and should be checked by the relevant links / connections reached the device.
Fi g ure 1-1 2nd item, if there is an error in the voltage phase during due to incorrect sequence; "Voltage phase sequence
error icon" will appear. If this icon appears; phase-sequence voltage should be checked.

3 MENUS
3.1 INSTANTANEOUS MEASUREMENT MENUS
Voltage (L-N and L-L), current, neutral current, cosØ, power factor, active power, reactive power, apparent power,
THDV and THDI values are shown in instantaneous menu.
Menu are given the name of which is shown in Menu bar.
The values shown on the display is expressed in what phase or phases at the lower left corner of the display
numbers.
Phase Numbers are not displayed at Menus which display avarege, total and other properties of network. In this
case phases are displayed in 2. Level.
Next to each index value unit of respective rows are indicated. It also states that inductive or capacitive phases
are indicated next to the relevant indicators.
Table 1-3 for parameters displayed in the menus.
POWER Q
Figura 3.1: Instantaneous Measurement Menus (Reactive Power)
CAUTION!
When the product is mounted on a panel which consumes power, active power (P) must be positive. If active power is
negative, operator should cross connect k-l leads of the current transformer.
When the product is mounted on a panel which generates power, active power (P) must be negative. If active power is
positive, operator should cross connect k-l leads of the current transformer.
3.2 MAXIMUM, MINIMUM VE DEMAND MENUS
Minimum and maximum values are calculated and stored in the non-volatile memory for below parameters:
Voltage (phase-neutral, phase-phase);
Neutral current;
Frequency;
CosØ;
Power factor;
THDV;
THDI.
