7. How to wire
7.1 Wiring
Follow the wiring diagram for external connections of this unit.
When using this unit, current sensor (EMU-CT50/CT100/CT250/CT400-A/600-A, EMU2-CT5 or EMU2-CT5-4W) is necessary.

* Fuse:P405H (by Daito Communication Apparatus Co., Ltd) equivalent.
* For a low voltage circuit, grounding of the secondary sides of VT (or CT) is not necessary.
・Make sure that before connecting the cable, the orientation of the current sensor is correct for attachment. K to L is the correct direction. K: power source side, L: load side
・EMU-CT50, EMU-CT100, EMU-CT250, EMU-CT400-A,EMU-CT600-A are extendable up to 50m.
・EMU2-CT5, EMU2-CT5-4W are extendable up to 11 m, using together with a extension cable. To extend the wire further, use the current transformer CW-5S(L) for split-type instrument in combination, extending the secondary wiring on
CW-5S(L) side.
・EMU-CT50/100/250/400-A/600-A is used only for low voltage circuit. (Maximum voltage: 460V) It cannot be used for a high voltage circuit. EMU2-CT5 and EMU2-CT5-4W should be used with the secondary side (5A) of transformer transfixed.
If they are used for the circuit directly, they should be used under 200V. (Maximum voltage: 260V)
・Maximum voltage of the circuit connected to this unit directly is 260V for EMU4-BD1-MB, or 277 / 480V for EMU4-HD1-MB. For the circuit over this voltage, use the transformer. Using the transformer, primary voltage is configurable up to
6600V. secondary voltage is fixed to 110V. (special Primary voltage of VT can be set up to 6600V in any, and special secondary voltage of VT can be set up to220V in any.)
・When screwing the terminals at both ends of the terminal block, be careful not to touch the projection of the terminal block cover.
・For MODBUS RTU communication wiring, recommended to have the extra length wires about 200mm (When extended to B / NET transmission from MODBUS RTU communication, use of MODBUS RTU communication wiring is possible).
・Do not ground the secondary side of the current sensor.
*When showing the display part by cutting the panel face in mounting the IEC rail, cut the
panel at where it is more than 50mm away from the fulcrum of the open / close of the door.
・Dimensions of hole panel(77×45.5)
・Mounting
The panel hole dimensions are as shown below. Mount the unit to mounting plate by mounting screws (M3×10),
And it can be attached to a panel of thickness
then mount the panel mounting attachment.

・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. Keep distance as below
between them. (except for the terminal block)
Condition distance
High-voltage line 600V or less 300mm or longer
Caution
Other high-voltage line 600mm or longer
・For the actual usage, connect the FG terminal to ground. (D-type ground: Type 3) Connect it
directly to the ground terminal.
This is being bonded to the conductive part of the product for safety reasons and being
connected to the terminal which is connected the outside protection grounding system.
・Do not connect to FG terminal during the insulation resistance test and pressure test.
7.2 How to connect wires
・Use appropriate crimp-type terminal.
・Use electric wires as below, and tighten the terminal screws by the torque as below.
