Installation
In Australia and New Zealand, please connect the AC wiring as shown in
Figure 3-10. The connection between Grid N and Load N is necessary due
to the grid code requirement to ensure the continuity of the neutral conductor
when inverter is in standalone mode.
The integrated all-pole sensitive RCMU provides additional safety. RCD Type A
can be used for this unit. Minimum tripping current 30mA of the type A RCD is
recommended for Load connection.
- Short circuit occured at the backup power load may cause damage to the unit.
- Motor and half-wave rectification Load is not suitable for backup power load, it
will lead to error and cause unit shut down.
