It is recommended to install an upstream circuit breaker between AC side and
inverter side for over current protection.
The AC cable must be jacketed and meet the specifications in Table 4-3.
If there is any conflict between Table 4-3's specification and local electrical code,
please follow the electrical code.
RPI M50A support both 3P3W (3phase and PE) and 3P4W (3phase, N and PE)
connections.
End sleeve for each wire is necessary if 25mm

or 3AWG is applied.
End sleeve is not able to be installed if 1AWG is applied.
