Use M4 screws and spring washers (in four places) for
Antenna installation.
Tighten the screws to a torque of 0.7 to 1.2 N⋅m.
There are no restrictions on the mounting direction or
the direction of access to the RF Tag, but if the Antenna
is to be installed near a device such as a conveyance
belt, make sure there is no danger of the Antenna being
accidentally struck.
Note: When installing the Antenna, mount it on the
enclosed Mounting Bracket. The Mounting
Bracket is not necessary, however, if the Antenna
is mounted on a metal base that is larger than the
Antenna (100 × 100 mm).
