3.4 Wiring Main Circuit Terminals

◆ Closed-Loop Connectors Size
Yaskawa recommends using closed-loop crimp terminals.
UL/cUL approval requires the use of closed-loop crimp terminals when wiring the main circuit terminals.
Use only the tools recommended by the terminal manufacturer for crimping.
Table 3.6 Closed Loop Connectors Sizes (JIS C 2805) (For 200 V/400 V classes)
Note: Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage. Line voltage drop is calculated as follows:
(If there is a possibility of excessive voltage drop, use a larger wire suitable to the required length.)
Line voltage drop (V) = 3 x wire resistance ( Ω/km) x wire length (m) x current (A) x 10 -3
