3.3 Installation and Wiring Precautions

Make sure to use the module by following cautions of this section. Improper use may impair protection provided bythis module.

・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 a damage of the module.

Danger

・Shut off the power supply for the module in all phases before installing or wiring. Failure to do so may cause an electric

shock or a damage, a fire on the module.

・Any person who is involved in the installation and the wiring of this Programmable Controller should be fully competent

to do the work.

・Secure the spatial distance more than 100 mm in all directions (other than back). ・Use the programmable controller in an environment that meets the general specifications in the MELSEC iQ-R Module

Configuration Manual.Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product. After mountingthe module, ensure that the module fixing hook is securely applied on the base unit and the module is

・

surely mounted.Incorrect mounting may cause malfunctions, a failure or a drop of the module. When using the Programmable Controller in an environment of frequent vibrations, fix the module with a screw.

・Tighten the screw within the specified torque range. Loose tightening can cause drop of the screw, short circuit or

malfunction. Over tightening can damage the screw and/or modul

・Do not directly touch any conductive part of the module. Doing so can cause malfunctions or a failure of the module. ・When using this module, make sure to use it in combination with the dedicated current sensor. Do not exceed the rating

of the module for input of the current sensor. A secondary side (5A) of transformer cannot directly input to this module. For further details, refer to the manuals for the curren module.

・The dedicated current sensor is used only for low voltage circuit. It cannot be used for a high voltage circuit. EMU2-CT5

and EMU-CT5-Ashould be used with secondary side (5A) of transformertransfixed. If it is connected with a high voltage circuit by mistake, it may cause a burnoutof the device and a fire. It is critically dangerous. For the allowance maximum voltage of current sensor, refer to the Us

・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 strips 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

Caution

preventive label is placed on the module. While a wiring work is perf operating the system, peel off the label for heat release. If the foreign-object preventive label is not peeled off 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 break 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 devicemalfunction, 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 malfunction, a fire, or an electric shockon the device.

・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 t

assignment. If the input voltage exceeds 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 prevent persons with little knowledge about electric equipment from electric shock, panel must be taken either
