Grounding the Communication Cables
For better signal noise immunity, it is recommended to connect either end of the
cable shield at the SHIELD terminal (both-end grounding method).
*1 (If many power
machines are used near the modules and grounded locally, however, use the single-
end grounding method to protect against noise from stray current.)

*1: To conform the equipment incorporating this module to CE marking, use shielded cables.
In addition, remove the cable covering to expose the shield, and then ground and
secure it using an FG clamp.

Setting terminating resistors
F3LP32-0N has an in-built termination resistor (110Ω). FA Link modules on both
ends of the transmission path must have their Termination Resister ON/OFF switch
set to ON (See Figure 3.6.5).
FA Link modules not located at either end of the transmission path must have this
switch set to OFF.
