Dust, corrosive gas, saline and oil smoke exist. Vibration and impact exceed the specifications. Installed excluding the control panel.

3.2 Matters concerning the preparation before use Use the module in the specified usage environment and conditions. The setting of this moduleprimary voltage, primary current necessary before using it. Please refer to "Users Manual (Details)" about each setting method.

3.3 Installation and Wiring Precautions

Danger Shut off the external power supply for the module in all phases before installing or wiring. Failure to do so may cause an electric shock or damage of the module.

Caution

Any person who is involved in the installation and the wiring of this Sequencer should be fully competent to do the work. Use the programmable controller in an environment that meets the general specifications in the Users Manual for the CPU module used. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.

To mount the module, while pressing the module-mounting lever located in the lower part of the module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it snaps into place. Incorrect mounting may cause malfunction, failure or drop of the module. When using the Sequencer in an environment of frequent vibrations, fix the module with a screw.

Tighten the screw within the specified torque range. Under tightening can cause drop of the screw, short circuit or malfunction. Over tightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

Shut off the external power supply for the system in all phases before mounting or removing the module. Failure to do so may result in damage to the product.

Do not directly touch any conductive part of the module. Doing so can cause malfunction or failure of the module. FG terminal must be grounded according to the D-type ground (Type 3) dedicated for sequencer. Failure to do so may result in an electric shock or a malfunction.

When using this product, make sure to use it in combination with current sensor (EMU-CT series or EMU2-CT5-4). Please not to exceed the rating 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 dedicated current sensor (EMU-CT50/CT100/CT250/CT400/CT600) is used only for low voltage circuit. It cannot be used with a high voltage circuit. Also, EMU2-CT5-4W 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.

Measurement circuit voltage cannot be input directly into the module. Please enter the output voltage of the voltage transform unit (QE8WH4VT)

The dedicated current sensor has a polarity (directionality). Be careful about it when installing the module. Take care not entering any foreign objects such as ships and wire pieces into the module. It may cause a fire, a 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 placed in a duct or fixed together by clamping. If the electric wires are not placed in the duct or clamped together, loosen wires or their movement or careless stretch may cause a breakage of the module or wire or a malfunction due to poor contact of electric wires.

Use appropriate size of electric wires. If inappropriate size of electric wire is used, it may cause a fire due to generated heat.

In case using stranded wire, take measures so that the filament should not vary by using a bar terminal or by processing the point twisted. Use the bar terminal appropriated for the size of electric wires. If inappropriate bar terminal is used, a wire breakage or a contact failure may occur, which may cause a device malfunction, a failure, a burnout, or a fire.

After inserting the electric wire or a bar terminal, make sure that no missing insertion is existing. Missing insertion may cause a device malfunction, a fire, or an electric shock.

or the wire. If the wires connected to the module are strongly pulled off, it may cause a malfunction or a breakage to the module

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. (Tensile load: 22N or less)

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 electric 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.

6.1 Wiring Follow the wiring diagram for external connection of QE81WH4W. Current sensor (EMU-CT50/CT100/CT250/CT400/CT600, EMU2-CT5-4W) is necessary for the connection of the current circuit. Voltage transform unit (QE8WH4VT) is necessary for the connection of the voltage circuit.In addition,up to five QE81WH4W modules can be connected to one voltage transform unit. Please refer to the Users Manual (Details) of this module,and the installation method and the detailed specifications of the current sensor and the voltage transform unit.

Make sure that before connecting the cable, the directionof the current sensor is correct for attachment. K to L is the correct direction. K: power source side, L: load side.

The available range of the voltage transform unit is from 55/95VAC to 227/480VAC. When this product is used in a circuit more than 227/480VAC,voltage transformer is required. The available phase voltage of the transformer is up to 6600V. Connect the secondaryside of the transformer to the terminal (P1, P2, P3, P0) of the Voltage transform unit.Make sure that terminal symbols are correct. This product cannot connect with the secondary side of the transformer directly.

6.2 How to connect wires Use appropriate electric wires and tighten a screw by appropriate torque as described right. Insert a wire to the terminal all the way until it touches the end. Voltage input terminals Stripping length of the used wire in use has to be 5 to 6mm. Check the stripping lengthusing the strip gauge of

QE81WH4W module. When stranded wire is used, twist the tip. Current input terminals When attaching and detaching cables to/from the terminal, use the push button. Check that the wire is securely inserted.

Stripping length of the used wire in use has to be 10 to 11mm. Check the stripping length using the strip gauge of QE81WH4W module. When stranded wire is used, a bar terminal or the tip-twisting are required to avoidwire scatting.
