[Installation Precautions] WARNING ● Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may result in electric shock or cause the module to fail or malfunction. [Installation Precautions] CAUTION ●...
Page 7
[Wiring Precautions] CAUTION ● Individually ground the FG and LG terminals of the programmable controller with a ground resistance of 100 ohms or less. Failure to do so may result in electric shock or malfunction. ● Use applicable solderless terminals and tighten them within the specified torque range. If any spade solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in failure.
Page 8
[Wiring Precautions] CAUTION ● Programmable controllers must be installed in control panels. Connect the main power supply to the power supply module in the control panel through a relay terminal block. Wiring and replacement of a power supply module must be performed by qualified maintenance personnel with knowledge of protection against electric shock.
Page 9
[Startup and Maintenance Precautions] CAUTION ● Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may cause the module to fail or malfunction. ● Tighten the screws within the specified torque range. Undertightening can cause drop of the component or wire, short circuit, or malfunction.

• When connecting between the MELSECNET/H network modules, the cable lengths indicated in the cable specifications must be used according to the number of stations connected. A communication error may occur if a cable length is out of the coaxial cable specifications. If there is a possibility of adding stations to extend the system, lay the cables considering the station-to-station cable length in advance.
