LOADING AND INSTALLATION
POINT
1. Use the thickest possible (max. 2 mm
2
(14 AWG)) wires for the 100/200VAC
and 24VDC power cables. Be sure to twist these wires starting at the
connection terminals. For wiring a terminal block, be sure to use a solderless
terminal. To prevent short-circuit due to loosening screws, use the solderless
terminals with insulation sleeves of 0.8 mm (0.03 inch) or less.
Also, only two solderless terminals can be connected per terminal block.
2. Supply power to two redundant power supply modules individually (redundant
power supply system).
3. When two redundant power supply modules (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.
4. When the LG terminals and FG terminals are connected, be sure to ground
the wires.
Otherwise, the programmable controller may be susceptible to noise.
Since the LG terminal has a half of the input voltage, touching this termial may
result in an electric shock.
