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 connec-
tion terminals. For wiring a terminal block, be sure to use a solderless termi-
nal. 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. When 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 terminal
may result in an electric shock.
3. No system error can be detected by the ERR
terminal of an extension base
unit. (The ERR
terminal is always set off.)
