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 15 and after.
For more information about the factory default settings, refer to the setting table on page 64.
CAUTION
Keep in mind that when a setting is changed, the related setting items and measurement data
will be reset to the default settings. (Refer to page 30.)
