8. Routing the cable to the inverter
The cable routing have to be done in order to avoid water dripping to the:
• AC panel cable glands
(11)
(56)
• DC input quick fit connectors
(16)
• DC input cable glands
(18)
• Signal cable glands
(12)
.
Expecially when coming from the top, the cables must be routed in order to create a loop: in this way the water that flows on the cables
will be drained.
The AC and DC conductors must be anchored or supported in order to prevent loading and mechanical stress on the cable glands and
quick fit connectors causing potential damage on the AC and the DC plates.
The pictures below are showing some example of incorrect and proper cable routing.

In case of the AC cable glands

was accidentally removed during the cable routing phase, it will needed to assure
the correct tightness of the lock nut of the cable gland to the inverter chassis with a tightening torque of 8.0 Nm (for each cable gland).
