5.4 Preparing the Enclosure Opening on the Inverter
Procedure:
1. Prepare the cable gland:
• If the enclosure opening of the inverter is sealed
with a filler plug, push the filler plug out of the
enclosure opening.
• If the enclosure opening of the inverter is sealed
with a cable gland installed in reversed
manner, loosen the external counter nut and
remove the cable gland.
2. Insert the cable gland from the outside and tighten
it with the counter nut from the inside.
3. If two cables must be led through the cable gland, press out the single-hole seal and replace
with a two-hole seal. Make sure that the enclosure opening of the inverter is tightly sealed.

Using example illustrations, this section shows only the preparation of the enclosure openings
on the inverter Sunny Tripower. However, the same method is used to connect to the module in
all inverters. Only the inverter environment is different.
