6.4.6 AC Input and Output
WARNING !!!
Recommendation of IEC 60364 4. 43
431.3 Disconnection and reconnection of the neutral conductor in multi-phase systems
Where disconnection of the neutral conductor is required, disconnection and reconnection shall be such that the
neutral conductor shall not be disconnected before the line conductors and shall be reconnected at the same
time as or before the line conductors.
WARNING !!!
Input Neutral is required to operate the
Inverter, UPS
In TN-S System no 4 pole input switch or
circuit breaker shall be used. If you have to
use 4 pole protective device, be aware that
the neutral against the ground is floating.
The inverter, UPS will operate without
problem but you may infringe the local
regulation.
