Notes on Use
Wiring
• A qualified electrician shall perform the wir-
ing to prevent electric shock.
• Avoid live-line electrical work to prevent
electric shock and accidents due to short-
circuiting.
• 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 fin-
ished. This will prevent module trouble
and electric shock.
• Ensure that the power supply module and
input are OFF when connecting or discon-
necting the module to the system. This will
prevent electric shock, errors, and mal-
function.
• Avoid using an unused terminal for relay-
ing or any other purpose to prevent electric
shock, errors, and malfunction.
• The core end of the clamp sensor is not
insulated. To prevent injury, avoid short-
circuiting a charged part of the object to be
measured with the core.
