Dust or other foreign matter might accumulate on the connector, resulting in
poor contact. Immediately after the module is unpacked, perform the
mounting and wiring procedures.
To prevent the module from being damaged, observed the following
precautions when you mount or demount the module:
• Before mounting the module to the mount base connector, check that the
connector pins are properly aligned and not bent, broken, or soiled with dirt
or the like.
• Ensure that the module is parallel to the mount base vertical surface as
shown below when mounting. If you connect a module to or disconnect it
from its connector while it is tilted, the connector pins may become damaged.
• If the mount base is positioned overhead due to the employed enclosure
structure, use a stepladder or the like and mount the module squarely. If
you mount the module obliquely, the connector may become damaged.
Mount base
(chapter 3, page 3-5)
Insulate the mount base from the enclosure. To keep the mount base
insulated, avoid removing the insulation sheets that are supplied with the
mount base.
The LG is a ground terminal for power supply noise. The FG and SHD are
ground terminals for the noise in the remote I/O, communication module and
other external interface lines. To avoid interference between the ground
terminals, separately ground the LG and FG.
