CAUTION FG terminal must be grounded according to the D-type ground (Type 3) dedicated for sequencer.
Failure to do so may result in electric shock or malfunction. When using this product, make sure to use it in combination with current sensor (EMU-CT***,
EMU-CT***-A or EMU2-CT5-4W) and Voltage transform module (QE8WH4VT). Please not to exceed the ratings of this product for input of current sensor. For further details, please refer to current sensor manual to maintain the functionality and the accuracy of this product. The available range of the voltage transform module is from 63.5/110 to 277/480V AC. When used in a circuit more than 227/480V AC, voltage transformer is required.
Current sensor (EMU-CT***, EMU-CT***-A (Excluding EMU-CT5-A)) is used only for low voltage circuit. It cannot be used with a high voltage circuit. Also, EMU2-CT5-4W and EMU-CT5-A should be used with the secondary side (5 A) of transformer transfixed. If it is connected with a high-voltage circuit by mistake, it may cause a burnout of the device and a fire. It is critically dangerous. For the Allowable maximum voltage, refer to Appendix 2 Optional devices.
Current sensor has a polarity (directionality). Be careful about it when installing the module. Do not open the secondary side of current sensor. Take care not entering any foreign objects such as chips and wire pieces into the module. It may cause
a fire, failure or a malfunction. In order to prevent the module from incoming foreign objects such as wire pieces during wiring work, a
foreign-object preventive label is placed on the module. While a wiring work is performed, keep the label on the module. Before operating the system, peel off the label for heat release. If the foreign-object preventive label is not peeled and the system is in use, residual heat inside the module may reduce the product life.
The wires to be connected to the module shall be put in a duct or fixed together by clamp. If not, the loosing and unstable wire or careless stretching results in poor contact of electric wires. That may cause a breakage of the module or wire or a malfunction.
After wiring, confirm whether there is a wiring forgetting or a faulty wiring. They may cause a device malfunction, a fire, or an electric shock.
When removing the wires connected to the module, do not pull wires as holding on their electric wire portions. Push the buttons on the terminal, and then remove the wire.
If the wires connected to the module are strongly pulled off, it may cause a malfunction or a breakage to the module or the wire. (Tensile load: 22 N or less)
Ensure the wiring to the module properly, checking the rated voltage and current of the product and the terminal pin assignment. If the input voltage exceed the rated voltage or the wiring is improper, it may cause a fire or a breakage.
Do not exceed the specified voltage when doing an insulation resistance test and a commercial frequency withstand voltage test.
To protect persons who do not have adequate knowledge of electric equipment from elevtric shocks, any of the following measures should be taken for the panel.
(a) To lock the panel so that only trained persons having adequate knowledge of electric equipment can open it.
(b) To design the structure so that the power is automatically interrupted upon opening of the panel. The protection class of the panel should be IP2X or higher. Terminal screws must be tightened to the specified torque. Loose terminal screws may cause a short
circuit or malfunction. If terminal screws are over-tightened, the screws or the module may be damaged, causing a short circuit or malfunction.
For specified torque, refer to Section 8.1 Precautions for handling. Use an applicable solderless terminal for the current input line and tighten it to the specified torque. If a
spade terminal is used, it may fall, causing a breakage of the module when the terminal screw is loosened.
Use appropriate size of electric wires. If inappropriate size of electric wire is used, it may cause a fire due to generated heat. For appropriate size of electric wires, refer to Section 8.5.2 How to connect wires.
In case using stranded wire, take measures so that the filament should not vary by processing the point twisted.

(4) Restrictions for measuring data
- Measurement cannot be performed immediately after the power loading to the sequencer
system (Module ready signal is under the OFF condition).
After checking that Module ready (Xn0) is ON, obtain measuring data.
- Measurement cannot be performed immediately after operating conditions are set up to the
module. After checking that Operating condition setting completion flag (Xn9) becomes ON,
obtain measuring data.
- Behaviors during operation are as follows:
Measuring item Behavior of the module
Current When the input current is less than 0.4 % of the rating current, it
becomes 0 A.
Current demand Current demand is obtained by current moving average. Therefore,
even if current is 0 A, current demand may not be 0 A.
Voltage (L-N) When the input voltage (L-N) is less than 55 V, it becomes 0 V.
If there is no input at voltage V1N, all measurement cannot be
done.
Voltage (L-L) When the input voltage (L-L) is less than 95 V, it becomes 0 V.
