Connection of protective ground cables (PGND)
Connect the inverter and the batteries to the grounding electrode using protective ground cables
(PGND).
The inverter does not have a transformer, therefore the positive and
negative polarities of the PV array do NOT have to be grounded.
All the metal parts in the photovoltaic supply system that do not carry
current must be grounded (e.g. PV module frame, PV bracket, dialler
housing, inverter housing).
Attention
The PGND cables are pre-set cables (external power supply cables ≥ 4mm
2
are recommended for
grounding purposes), the cable must be a yellow-green colour.
Procedure:
1.
Remove a suitable length of the insulating layer using a wire stripper,
NB:
L2 is 3mm longer
than L1.
