Earth Connection - LIVOLTEK GT1-2K5D2 User Manual

6.4 Earth connection(mandatory requirement)
WARNING
• Earth connection essential before connecting supply
• Be sure that AC power source is disconnected before attempting to
hardwire i t to the unit.
NOTICE
•
Good grounding is good for resistance to surge voltage shocks and
improves EMI performance. Therefor,before connecting AC，DC and
communication cables, you need to ground the wires.
• For a single inverter, simply ground the PE cable; For multi-inverter, the
PE cables for all inverters need to connected to the same grounded
copper strip to ensure an equipotential connection.
•
If the PV end of the inverter is not connected with earth, the inverter will
turn on a red light inspect and report Earth Fault. this inverter complies
with IEC 62109-1 clause 13.9 for earth fault alarm monitoring
Procedure:
Model Wire Size Cable
