∙ Be sure to install an exclusive power supply. If you
use a power strip for multiple electrical connections,
there is a risk of electric shock or fire.
∙ Be sure to install a circuit breaker with a rated current
sensitivity of over 30 mA.
∙ Fasten the screws on the terminal block to be within
the rated range and so that they do not loosen.
∙ Be sure to connect the ground wire. Install the power
wire and make sure it is shorter than 50 m. If the
length of the power wire exceeds 50 m, the product
may not work properly or the wire may be damaged.
