The following are precautions related to connection to the signal input/output terminal block.
The precautions described here are important for safety.
Make connections after properly understanding the description.
WARNING
●Do not connect commercial power directly to the signal input/output terminals.
●Make connection to the signal input/output terminals with no power applied
because you may receive an electric shock.
●For connections to the signal input/output terminals, carry out wiring properly after
confirming the signal names and pin assignment numbers.
●Use of the F350 is limited to category II specified by EN61010. Overvoltage applied
to the signal input/output terminals should not exceed the value defined to category
II.
●After wiring, make sure to mount the attached terminal block cover. Otherwise, you
may receive an electric shock.
●Turn on the power after carefully checking the wiring, etc.
●Do not touch the signal input/output terminals while the power is on. Otherwise, you
may receive an electric shock, or a malfunction may occur.
●The F350 conforms with EMC Directives as a product used in industrial
environments (class A). If it is used in living environments, radio disturbance may
occur. In that case, take suitable measures.
CAUTION
●Tighten the terminal screws at specified torque. If the terminal screws are loose,
short-circuiting, fire, or a malfunction may occur.
●Use shielded cables.
