"C" is multiples of the tripping current at 0.01 s.
Obtain the value of "C" from the tripping characteristic of the breaker that is used on site.
<Example of "F2" calculation>
Conditions: PEFY-VMS × 4 units, PEFY-VMA × 1 unit, "C" = 8 (See the sample chart.)
F2 = 18.6 × 4/8 + 38 × 1/8
= 14.05

・The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one size
thicker in diameter. Make sure the power-supply voltage does not drop more than 10%. Make sure that the
voltage imbalance between the phases is 2% or less.
・Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed
flexible cord (design 60245 IEC57). For example, use wiring such as YZW.
・This unit is intended for the connection to a power supply system with a maximum permissible system
impedance shown in the above table at the interface point (power service box) of the user's supply.
・The user must ensure that this unit is connected only to a power supply system which fulfils the requirement
above.
If necessary, the user can ask the public power supply company for the system impedance at the interface point.
・This unit complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to
Ssc* at the interface point between the user's supply and the public system. It is the responsibility of the
1
installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary,
that the equipment is connected only to a supply with a short-circuit power Ssc greater than or equal to Ssc*
