indicates a fuse.
• The power for the analog module
should be supplied separately from
the LT.
Turn the analog module on before
turning the LT on. Wait at least 30
seconds after power-off to restart the
external power-supply or it may not
operate properly.
• Be sure the analog IN/OUT lines
(especially, Temperature Probes) are
placed in a separate duct from high-
frequency, live lines such as high-
voltage, high-power lines, inverters,
etc.
• Connect a fuse appropriate for the
applied voltage and current draw, at the
position shown in the diagram.
• Do not connect cables to a channel that is
not used. When the input is open, an
error code (RGEF130 input data error)
occurs to the unused channels, then the
invalid values are input. Do not map the
parameters on the unused channels.
• When connecting an RTD, connect the
three wires to terminals A, B', and B of
input channel 0 or 1.
• When connecting a thermocouple,
connect the two wires to terminals B' and
B of input channel 0 or 1.
