● Use the thickest possible (max. 2mm
the connection terminals. Use a solderless terminal for wiring a terminal block. To prevent short-circuit due to loosening
screws, use the solderless terminals with insulation sleeves of 0.8mm or less.
Note that up to two solderless terminals can be connected per terminal block.
● Supply power to two redundant power supply modules individually (redundant power supply system).
● When two redundant power supply modules (Q64RPN, and Q64RP) are placed together and operated as a redundant
power supply system, it is recommended to use one of them as an AC power input and connect the other to an
uninterruptible power supply to the other.
● When the LG and FG terminals are connected, ground the wires.
If not, the programmable controller may become susceptible to noise.
The LG terminal has a half of the input voltage.
