--------------------
MELSEC-A
POINTI
(1) Use
the
thickest possible (max. 2 mm
2
(14 AWG» wires
for
the
1
00/200
I
VAC and
24
VDC power cables. Be sure to
twist
these wires starting
at
the
connection terminal. To prevent short- circuit should
ant
screws
loosen, use solderless terminals with insulation sleeves.
(2) When the LG terminals and FG terminals are connected, be sure to
ground
the wires. Do not connect
the
LG terminals and FG terminals
to anything other than ground. If LG terminals
and
FG terminals are
connected without
grounding
the wires,
the
PC may be susceptible to
noise, also since the LG terminals have potential,
tile
operator
may
get
an electric
shock
when
touching
metal parts.
(3) * : Open/shortcircuit switching is performed by power
supply
voltage.
100
VAC : Shortcircuit
200
VAC : Open
(4) Connect
the
shield of a Twisted-pair shield cable to
the
SLD
ter-
minal on
the
receiving side (on
the
connecting side of RDA
and
ROB).
