When switching power on again, switch power on more than five seconds after
switching power off. Failure to do so may cause an inrush current of higher than
the specified value to flow.
* 1 : Use "double-shielded coaxial cables" when configuring a coaxial bus system on a MELSECNET/H
remote I/O network.
Refer to the following manual for the double shielded coaxial cables.
Q Corresponding MELSECNET/H Network System Reference Manual (Remote I/O
network)
* 2 : Diagnostics includes PLC diagnostics, Ethernet diagnostics, CC IE Control diagnostics,
MELSECNET diagnostics, and CC-Link/CC-Link/LT diagnostics.
For details, refer to each network manual.
