Main Circuit Terminal Wiring
Yaskawa recommends using closed-loop crimp terminals on all converter models. To maintain UL/cUL approval,
UL-Listed closed-loop crimp terminals are specifically required when wiring the converter main circuit terminals on
models 2A0030 to 2A0130, 4A0030 to 4A0630. Use only the tools recommended by the terminal manufacturer for
crimping. Refer to
Closed-Loop Crimp Terminal Recommendations on page 244
for closed-loop crimp terminal
recommendations. The wire gauges listed in the following tables are Yaskawa recommendations. Refer to local codes for
proper wire gauge selections.
Note:
The mark indicates the terminals for protective ground connection as defined in IEC/EN60417-5019.
Grounding impedance:
200 V: 100
