Before Installation
■ Appropriate static elimination method
Pay attention to the following points to ensure that static elimination is performed appropriately.
Static elimination cannot be performed accurately at locations where the target object is
touching a metallic body (earthed body).
Eliminate static from the target object at locations where it is not directly touching metallic bodied
(earthed body).
Static will be eliminated from only the surface of the insulated body (board, etc.) that is facing
the Static Elimination Head.
When eliminating static from both sides of a target object, install two SJ-M Series as one SJ-M Series
must be installed on either side of the target object.
Install the Static Elimination Head so that it can be easily accessed, for example, for
replacement of parts and cleaning.
Installation Precautions
■ Installation site
Install the tip of the SJ-M010/020(G) paying attention to the following point.
• Install the Static Elimination Head away from the wall or surrounding
objects.
• Protect the area around the tip of the Static Elimination Head with silicon,
fluoro-resin or other highly ozone-resistant resin. Ozone that is generated may
cause the metal or resin on the SJ-M010/020(G) to rust, corrode or deteriorate.

Before Installation
• Do not install the Static Elimination Head at locations where moving parts of
other equipment and machinery may place stress on the cable. Doing so
might cause the SJ-M010/020(G) Series to malfunction.
■ Interference
The Static Elimination Head may not function properly if there is a conductor (earthed body) located
nearby or if two or more units are used close to each other. In such an installation, refer to the figure
below and maintain the indicated distance between the conductor (earthed body). If a conductor (earthed
body) is located inside the distances indicated below, adjust using the ion balance manual setup.
"Ion Balance Adjustment Function" (page 8)
When two SJ-M Series units are used, refer to the figures below, and install the units so that the
following distances are maintained between the two Static Elimination Heads.
