This section summarizes the precautions on conformance to the EMC Directive of the cabinet con-
structed using this Instrument.
However, the method of conformance to the EMC Directive and the judgment on whether or not the cabinet con-
forms to the EMC Directive has to be determined finally by the manufacturer.
1. EMC Standards
The standards applicable to the EMC Directive ( No.89/336/EEC ) are listed below.
(1) Radiated radio frequency emission ----------------------------------- EN61000-6-4/2001
(2) Radiated radio frequency electromagnetic field immunity ------EN61000-6-2/2001
2. Installation (EMC directive)
The instrument is to be mounted on panel of a cabinet.
Therefore, the construction of a cabinet is important not only for safety but also for EMC.
The instrument is examined by the following conditions.
●Use a conductive cabinet.
●Six faces of a cabinet have to be ensured conductivity for each other.
●A cabinet has to be connected to earth by a thick wire of low impedance.
●Holes on faces of cabinet have to be 10 cm or less in diameter.
●The terminals for protective earth and functional earth have to be connected to earth by a thick wire of low
impedance. (A terminal for protective earth is important not only for safety but also for EMC.)
●All connections keep inside the cabinet.
●Wirings outside the cabinet have to be used with the shielded cable.
The following diagram shows how to provide good contact of the shielded cable.
Remove part of the outer cover.
Remove part of the paint musk on the cabinet.
Connect those parts with the clamp.
Protective earth: Maintains the safety of the instrument and improves the noise resistance.
Functional earth: Improves the noise resistance.

The ME110NSR series is an instrument for measuring and metering electrical values for three-phase
LV/HV electrical networks.
■Various measurement parameters
■4 measurement items appear on one display
By combination of bar graph and digital 3-stage display, 4 measurement items can be displayed on one
display. For example, Voltage, current, power factor and active power can be displayed at the same time.
■RS485 interface, ModBus RTU(ME110NSR-MB)
■CC-Link communication
Measured values can be sent to PC or PLC via CC-Link communications. (ME110NSR-C)
■Analog 4 outputs + pulse output + alarm relay output (ME110NSR-4APH)
For example, the analog outputs of voltage, current, active power, and power factor, the pulse output of active
energy, and the alarm output of THD can be performed by one unit.
■Harmonics
It is equipped with harmonics current and harmonics voltage measurement function as standard one.
■Back light auto off function
It is equipped with energy saving mode function where the back light is turned off when there is no key
operation for 5 minutes.
