● Waterproong measures must be taken at the bottom of the electrical conduit.
The electrical conduit and cable must be vertical. Ensure that the upper end is
vertically routed into the maintenance compartment and the lower end is
vertically routed into the ground.
● After the electrical conduit is routed into the ground, the underground cable
must meet the bending radius requirements of the AC power cable.
● The bottom of the electrical conduit must be sealed with
waterproong
materials to prevent water or moisture from entering the electrical conduit and
reducing the cable insulation performance.
● Prevent stress on the inverter wiring terminals from the cable during
backlling.
● After stripping the jacket o the three-core cable, route the wires into the
inverter maintenance compartment as three single-core cables. Take
reproong and waterproong measures at the cable inlet of the maintenance
compartment to prevent water or moisture from entering the electrical conduit
and reducing the cable insulation performance.
● The armored layer of the cable must be grounded according to the design
requirements.
● Wires between the maintenance compartment and electrical conduit must not
be exposed to the air. Protective measures must be taken.
