Refer to Tables 5-2&5-3 for the specifications of the power cord and communication wire. A wiring capacity that is too small will cause the
electrical wiring to become too hot, and lead to accidents when the unit burns and becomes damaged.
Select the wire diameters( minimum value) individually for each unit based on the table 5-3.
Maximum allowable voltage range variation between phases is 2%.
Select circuit breaker that having a contact separation in all poles not less than 3 mm providing full disconnection，where MFA is used to select
the current circuit breakers and residual current operation breakers:
