The series inverter are designed for three phase grid. For the rated grid voltage
and frequency, please refer to the section “Technical Data”. Other technical
requests should comply with the requirement of the local public grid.
Micro-breaker should be installed between inverter and grid, any loads should
not be connected with inverter directly.
Note: Check the grid voltage and compare with the permissive voltage range
(refer to technical data).
a) Disconnect the circuit-bricker from all the phases and secure against re-
connection.
b) Select appropriate cable and prepare to strip the wires:
- Strip 82 mm of insulation from the cable end.
