Connecting PNGD cables (grounding)
Connect the 3PH 100KTL-136KTL-HV inverter to the ground electrode using ground protection cables
(PGND).
The inverter does not have a transformer, therefore the positive and negative
polarities of the photovoltaic string do NOT need to be grounded. Otherwise,
the inverter may fail. All non-current-carrying metal parts (such as the PV
module frame, PV rack, housing of the combiner box, and housing of the
inverter) in the PV power system must be connected to the ground.
Attention
Prerequisites:
Prepare the grounding cable (recommend 16mm² yellow-green outdoor cable and M8 OT Terminal).
Procedure:
1)
Remove the insulation layer with an appropriate length using a wire stripper shown in figure below.
Note:
L2 is approximately 2-3 mm longer than L1.
