After drilling holes on the bottom plate of the inverter, the remove all burrs and take
effective protection measures (waterproof terminal is optional) to prevent the cables
from scratch or abrasion.
Seal the gaps of the cable entries and around the cover plate by waterproof and
fireproof materials.
If there are communication and power distribution cable entries on the bottom of the
inverter, seal the gaps by using fireproof mud.
The sealing by fireproof mud should meet the waterproof and dustproof requirement.
Reassemble the insulation covers and protective covers removed before cable
connection.
The cable entries of the inverter are equipped with aluminum cover plate. Please do
not use cover plate of other materials to seal the cable entries. For details, consult
Sungrow.
