Wiring Precautions
When grounding a FG termi
nal, be sure to provide class 3 grounding which is dedicated
to the PLC.
Before the PLC wiring, be sure to check the rated voltage and terminal arrangement for
the module and observe them correctly. If a different power, not of the rated voltage, is
applied or wrong wiring is provided, it can cause a fire or disorder of the module.
Fasten the terminal screws firmly to the defined torque. If loosely fasten, it can cause
short circuit, a fire or malfunction.
Be careful that any foreign matter like wire scraps
should not enter into the module. It can
cause a fire, disorder or malfunction.
CAUTION
Test Run and Maintenance Precautions
Do not contact the terminals while the
power is applied. It can cause
malfunction.
When cleaning or driving a terminal
screw, perform them after the power
has been turned off.
Do not perform works while the power
is applied, which can cause disorder
or malfunction.
CAUTION
Do not separate
the module from the
printed circuit board (PCB), or remodel
the module. Th
ey can cause disorder,
malfunction, damage of the module or a
fire.
When mounting or dismounting the
module, perform them after the power
has been turned off.
WARNING
Waste Disposal Precautions
When disposing the module, do it as an industrial waste.
