Wiring Precautions
1.- Ensure the wires connected to rear terminals are propely done as
Shown rear terminal connection table.
2.- Turn OFF power, before changing the wiring of the temperature
sensor and other wiring.
3.- Be sure to match compensating cable with the thermocouple type.
also ensure that the polarity of compensating cable properly
Connected.
4.- Ensure that the compensating cable/signal wire route separately from
power wires to prevent electrically induce noise.
