 About power input cable
The power input cable supplied with this product varies in diameter as shown in Table 2-5. A
crimp-type terminal is attached to each cable on the end which is to be connected to the input
terminal of this product.
 On the supplied power input cable, the end which is to be connected to the distribution board
has no terminal attached. Use a crimp-type terminal appropriate for the terminal screw
diameter of the distribution board to connect the cable firmly.
 The supplied power input cable is dedicated only to this product. Do not use it with any other
product.
 When you use a power input cable other than the one supplied with the product, select a cable
which has an appropriate diameter in consideration of the safety standards and consumption
current. Use a protective grounding conductor of which diameter is the same or greater than
the power input cable.
