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.
