C: Multiple of tripping current at tripping time 0.01s
Please pick up "C" from the tripping characteristic of the breaker.
<Example of "F2" calculation>
Condition PEFY-VMS × 4 + PEFY-VMA × 1, C = 8 (refer to right sample chart)
F2 = 19.8 × 4/8 + 38 × 1/8
= 14.65
→ 16 A breaker (Tripping current = 8 × 16 A at 0.01 s)
* 5 Current sensitivity is calculated using the following formula.
G1 = V2 × (Quantity of Type1) + V2 × (Quantity of Type2) + V2 × (Quantity of Type3) + ···
+ V2 × (Quantity of Type16) + V3 × (Wire length[km])
G1 Current sensitivity
30 or less 30 mA 0.1 sec or less
100 or less 100 mA 0.1 sec or less

Notes:
1. Bear in mind ambient conditions (ambi-
ent temperature, direct sunlight, rain
water, etc.) when proceeding with the
wiring and connections.
2. The wire size is the minimum value for
metal conduit wiring. The power cord
size should be 1 rank thicker considera-
tion of voltage drops.
Make sure the power-supply voltage
does not drop more than 10%.
3. Specific wiring requirements should
adhere to the wiring regulations of the
region.
4. Power supply cords of parts of appli-
ances for outdoor use shall not be lighter
than polychloroprene sheathed flexible
cord (design 60245 IEC57).
For example, use wiring such as YZW.
5. install an earth line longer than power
cables
