●
Use an exclusive power supply at the controller’s rated voltage.
●
Be sure to install circuit breakers (ground fault interrupter, isolating switch, molded case circuit breaker,
and so forth) with the specified capacity. Ensure that the wiring terminals are tightened securely to
recommended torque specifications.
●
Clamp electrical wires securely with a cord clamp after all wiring is connected to the terminal block.
In addition, run wires securely through the wiring access channel.
●
When installing the power lines, do not apply tension to the cables. Secure the suspended cables at
regular intervals, but not too tightly.
●
Make sure that the terminals do not come into contact with the surface of the electrical box.
If the terminals are too close to the surface, it may lead to failures at the terminal connection.
●
Do not clean with, or pour water into, the controller as it could cause electric shock and/or damage the
unit. Do not use strong detergent such as a solvent. Clean with a soft cloth.
●
Check that the ground wire is securely connected. Do not connect ground wiring to gas piping, water
piping, lighting conductor, or telephone ground wiring.
