⚫Do not drop this instrument from high place. If you drop it and the display is cracked,
do not touch the liquid crystal or get it in your mouth. If the liquid crystal is touched,
wash it away at once.
⚫Work under the electric outage condition when installing and wiring. It may cause
electric shock, electric burn injury or damage of the device.
⚫When tapping or wiring, take care not to entering any foreign objects such as chips
and wire pieces into this instrument.
⚫If the terminal wiring is pulled with a strong force, the terminals may detach. (Tensile
load: 39.2N or less)
⚫When wiring in this instrument, be sure that it is done correctly by checking the
instrument‘s wiring diagram. Wrong wiring may cause failure of the instrument, a fire
or electric shock.
⚫Use electrical wire sizes compatible with the rated current. Use of unsuitable sizes
may cause heat generation, which may lead to a fire.
⚫Tighten the terminal screws with the specified torque and use the suitable pressure
connectors and suitable wire size. (Refer to page 58)
⚫In order to prevent invasion of noise, do not bunch the control wires or communication
cables with the main circuit or power wire, or install them close to each other. The
distance between communicational signal lines, input signal lines and power lines, and
high voltage lines when running parallel to each other are shown below.

⚫EN 61000-3-3
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.
⚫Conductive cabinet is used.
⚫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 must be kept 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.

To measure, it is necessary to use Setting mode to set the phase wire system, VT / direct voltage, and CT primary current.
From Operation mode, move to Setting mode and then set necessary items. Factory default settings will be used for items
that you do not set.
Only the settings in Setting menu 1 (basic setting) are needed for normal use. For more information about the settings, refer
to page 16 and after.
For more information about the factory default settings, refer to the setting table on page 67.
