Knockouts
Preparing
knockouts for
connection
IMPORTANT! The knockouts must be drilled out using a step drill bit only. The
maximum conduit sizes are ½ - 1 inch / 13 - 25 mm.
IMPORTANT! Void warranty if the conduit holes are drilled improperly.
-
Use suitable eye protection when
drilling out the knockouts.
-
Avoid drilling too far to ensure the
connection area is not damaged.
-
When drilling out the knockouts at
the back, place the inverter on an
even surface with the back up-
wards so that shavings and pieces
of plastic can fall out of the invert-
er.
-
If necessary, deburr the knockouts
with a suitable tool and remove the
drilling residues from the inverter.

When installing outdoors, only use waterproof conduit fittings and conduits.
▶
Seal the conduits in accordance with the pictures above on both sides.
