4 INSTALLATION AND WIRING

POINT

(1) Use the thickest possible (up to 2mm

) 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 a

short circuit should any screws loosen, use solderless terminals with insulation

sleeves of 0.8mm (0.03inch) or less.

Also, only two solderless terminals can be connected per terminal block.

(2) Ensure that the earth terminals LG and FG are grounded.

(Ground resistance :

100

or less)

If not, the programmable controller may become 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.)
