2. Preparation before Use
 About power input terminal
Screw
 About power input cable
The power input cable supplied with this product varies in diameter depending on the rated output 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.

Power
1.5 kVA 2.25 kVA
3 kVA 4.50 kVA
4.5 kVA 6.75 kVA

9 kVA 13.50 kVA
10.5 kVA 15.75 kVA
12 kVA 18.00 kVA
Note: The model of which rated output is 6 kVA or less contains either a power cable for both 100 V and 200 V
series input or a power cable only for 200 V series input, depending on the destination of shipment. The
dedicated cable only for 200 V series input must be used with power supply voltage of 170 to 230 V.
 Power source connection procedure
Check the current capacity of the single-phase distribution board before wiring. The wiring must be
performed by a professional engineer.
WARNING
 Before connecting this product to the power source, be sure to cut the power to the distribution
board. Otherwise, an electric shock might occur.
