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). 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 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. 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. Use the applicable solderless terminals (R1.25-3) for current input terminals. If inappropriate solderless 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. When using stranded wires for the voltage input terminals, strand the wire edges to prevent thin wires from loosening. After inserting the electric wire or a solderless terminal, make sure that no missing insertion is existing. Missing insertion may cause a device malfunction, a fire, or an electric shock. 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. Ensure the wiring to the module properly, checking the rated voltage and current of the product and the terminal pin assignment.
