Wiring
Only use sensors dedicated to the type of module.
To avoid damaging the instrument, do not connect any other sensors
than those dedicated to the instrument to its input terminals. Further, do
not connect any other signal sources to the terminals, as such signals
may lead to module damage due to excessive voltage or current.
• A qualified electrician shall perform the wiring to prevent
electric shock.
• Avoid live-line electrical work to prevent electric shock and
accidents due to short-circuiting.
• Ensure that the power supply, input, and output are cor-
rectly wired according to the wiring diagram. (See the sec-
tion on "Preparations" for each module.) This will prevent
fire, malfunction, and errors.
Connect the module to a power source that matches the
rating in order to prevent fire.
• Do not work on live lines. Such work may result in electric
shock or short-circuiting.
• Use cables of the proper sizes for the rated current. This
will prevent entire system errors and fire resulting from
broken wire.
• Use crimp connectors suitable for the cable sizes. This will
prevent module errors and fire due to broken wires.
• When tightening the screws, confirm that all screws are
securely tightened. A loose screw may result in module
errors, fire, or electric shock.
• Tighten the screws within the specified torque. Excessive
torque may damage the terminals. Inadequate torque may
result in module errors, fire, or electric shock.
• Ensure that the power supply module and input are OFF
until all wiring work is finished. This will prevent module
trouble and electric shock.
• Ensure that the power supply module and input are OFF
when connecting or disconnecting the module to the sys-
tem. This will prevent electric shock, errors, and malfunc-
tion.
• Avoid using an unused terminal for relaying or any other
purpose to prevent electric shock, errors, and malfunction.
