This unit is the open type device, which are designed to be housed within another device for prevention of electric shock. House this unit within the device such as the control
panel before use. (Indoor use)
For the precautions for the compliance of the system incorporating this unit with the EMC Directives, refer to the User's Manual (Details).
(Note) For the definition of the pollution degree and the over voltage category, refer to EN61010-1/2010.
3.2 Matters concerning the precaution before use
• Use the unit in the specified usage environment and conditions.
• To use this unit, Base unit (EMU4-BM1-MB EMU4-HM1-MB EMU4-LG1-MB, EMU4-CNT-MB) is necessary. As for Base unit, refer to User's manual (Details) of each Base unit.
• To set this unit, dedicated small-size display unit (EMU4-D65) is necessary. For the setting method, refer to User's manual (Details) of the display unit.
3.3 Installation and Wiring Precautions
• Shut off the external power supply for the unit in all phases before installing or wiring. Failure to do so may cause an electric shock or damage of
this unit.
Danger
• Work under the electric outage condition when installing and wiring. Failure to do so may cause electric shock, a failure of the unit, a fire etc.
• Any person who is involved in the installation and the wiring of this unit should be fully competent to do this work.
• Keep the space around this product (all directions except the back) is 30 mm or more (100 mm or more for UL standard compliance).
• When tapping or wiring, take care not to entering any foreign objects such as chips and wire pieces into this unit.
• Check the connection diagram when wiring. Wrong wiring may cause failure of the unit, a fire or electric shock.
• This equipment is class A as per EN 55011. This equipment is not intended for use in residential environments and may not provide adequate protection to radio reception in
such environments.
• For protection against noise, transmission lines and input/output lines shall not be placed close to or bound together with the power lines and high-voltage lines.
• Strip the wires with proper length. Overlong stripping length may cause short to next wire and electric shock. Shorter stripping length may cause contact failure.
• Take care not to short to next terminal by a filament. (Do not plate the wires with solder.)
• Do not connect more than two wires to one terminal screw of a terminal block for preventing loose contact and wires dropout.
• Use appropriate size of electric wires. If inappropriate size of electric wire is used, it may cause a fire due to generated heat.
• Tighten the screw within the specified torque. Under tightening can cause drop of the screw, short circuit or malfunction. Over tightening can damage the screw and/or unit, resulting in
drop, short circuit or malfunction.
Caution
• After tightening the screws, be sure to check all the screws tightened. Loose screw may cause malfunction of the unit, a fire or electric shock.
• Be sure to attach the terminal cover to prevent electric shock.
• Use the crimp-type terminal appropriated for the size of electric wires. If inappropriate crimp-type 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.
• FG terminal must be grounded according to the D-type ground (ground resistance is not exceed 100Ω).
• Do not directly touch any conductive part of the unit. Doing so can cause electric shock, failure or malfunction of the unit.
• The wires to be connected to this unit shall be placed in a duct or fixed together by cramping. If the electric wires are not placed in the duct or cramped together, loosen wires or their
movement or careless stretch may cause a breakage of the unit or wire or a malfunction due to poor contact of electric wires.
• If the wires connected to this unit are strongly pulled off, it may cause a malfunction or a breakage to the unit or the wire.
• 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 following measure.
Lock the panel so that only those who get an education about electric equipment and have sufficient knowledge can unlock, or shut off power supply automatically by opening the panel.
Cover the dangerous part of this unit.
3.4 Precautions for Use
• When use Energy Measuring Unit Analog Input Model (Model:EMU4-AX4)/ Energy Measuring Unit Pulse Input Model (Model:EMU4-PX4) with CC-link communication
unit(Model:EMU4-CM-C) and base unit(EMU4-BM1-MB, EMU4-HM1-MB, EMU4-LG1-MB), number of connectable show in the tables below.
