4. 5.5. Neutral cable cross-section
It is necessary to check:
a) the minimum cross-section of the neutral cable must equal one of the phase conductors.
b) the balancing of the loads across the three phases,
c) the values that will trip the protective devices.

4. 6.1. Input rectifier currents for Green Power 2.0
Operating conditions are as follows:
•
Input/output power supply voltage 3 x 400V,
•
Green Power 2.0 is operating at rated power and batteries are recharging.

4. 6.2. Mean current supplied by the battery when discharging
The mean current value is to be taken into account for sizing connecting cables between the battery and Green Power 2.0.

4. 6.3. Bypass current
(or output current to the load)
Operating conditions are as follows:
•
Input/output power supply voltage 3 x 400V, for 415V, the current value must be multiplied by 0.96
•
Green Power 2.0 is operating at rated power.
