Drill conduits

The bottom and sides of the IQ Combiner 5/5C are the best
locations to drill holes for conduit fittings. The rear conduit entry
below the busbar assembly is also supported.
Use a snap punch or other type of center punch to prevent the drill
from wandering. Drill a pilot hole with a smaller drill before using a
step drill bit.
Use only UL Listed rain-tight conduit fittings for wire entry into the
enclosure .
Recommendation:
1 IQ Battery
2 PV - Bottom
Output to main load center/IQ System Controller

4 Control cables
Risk of equipment damage. Do not drill conduit holes on the
top of the box or at any location that allows moisture ingress.
When drilling, consider the internal parts of the combiner.
Make sure that the holes do not interfere with the internal
workings, mechanics, or the dead front legs in the corners of
the combiner.
Best practice: Use a stepped drill bit to make the conduit holes.
Using a hole saw may crack the plastic housing.
As an alternative, use a sharp chassis punch with caution.
