(1)
Use the thickest possible (max.
2
mm*
(14
AWG)) wires
for
the
100/200
VAC and
24
VDC power cables. Be sure
to twist these wires starting at the connection termin-
als.
To
prevent short-circuit should any screws loosen,
use solderless terminals
with
insulation sleeves.
(2)
When the LG terminals and FG terminals are con-
nected, be sure to ground the wires.
Do
not connect
the LG terminals and FG terminals to anything other
than ground.
tf
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, the operator may get an electric shock
when touching metal parts.
