Notes on Use
8
• Be sure to tighten the screws within the
specified torque. Excessive torque may
damage the terminals. Inadequate torque
may result in module errors or the
generation of high voltage on the CT
secondary side, which may cause 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 system.
This will prevent electric shock, errors, and
malfunction.
• Avoid using an unused terminal for
relaying or any other purpose to prevent
electric shock, errors, and malfunction.
• Connect the module to a power source that
matches the rating in order to prevent fire.
• Ensure that the power supply, input, and output
are correctly wired according to the wiring dia-
gram. (See Chapter 3 "Preparations " (p.25))
This will prevent fire, malfunction, and errors.
• Use cables of the proper sizes for the rated cur-
rent. This will prevent module errors due to bro-
ken wire, malfunction due to opening of the CT
secondary side, overheating, and fire.
• Use crimp connectors of the proper sizes for the
cables. This will prevent module errors due to
broken wire, malfunction due to opening of the
CT secondary side, overheating, and fire.
