"7.Electrical lnstallation". Make sure that the components comply with National Electrical Code(NEC).
(2) Check to ensure that the power supply voltage is within ±10%
ot
the rated voltage.
(3) Check the capacity
ot
the electrical wires. lt the power source capacity is too low, the system cannot be started
