Wiring
CAUTION
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
All wiring must comply with applicable codes and ordinances.
Before wiring, be sure to turn off the power to the product.
Failure to do so might cause electric shock.
To connect the wires to the screw terminals, use crimp terminal lugs with insulation.
Failure to do so might cause fire or device failure due to short circuit.
Model TTY6023Z2000 adopts lead wire connection and the rest of the models adopt terminal connection.
Precautions for wiring
● Use M4 crimp terminals to connect wires to the Neostat screw terminals. (Tightening torque: 78.5 Nꞏcm)
● For connecting wires from the load, use 1.25 mm
2
or greater stranded annealed copper wires with insulation.
● For splicing lead wires (from the load and from Neostat), use crimp sleeves with insulation.
● Correctly connect the wires from the load to Neostat.
● Make sure that all the wires are tightly connected.
