All wiring and maintenance on the KAM OWD must be done in accordance with regional and classification re-
quirements. It is the user's responsibility to understand these requirements.
It is also recommended that the OWD be wired with flexible wiring/conduit with additional slack/length in the
wire to accommodate insertion, removal, and testing.
Operator's should take all possible precautions to avoid any moisture from entering the electronics enclosure.
The enclosure should not be left open in inclement weather or for long periods of time, especially during opera-
tion as condensation will accumulate. Lid should be tightly screwed shut, all conduits should be sealed and
secured in accordance with regional and classification requirements, and unused 3/4" NPT openings should be
seal with provided plug. Do not power wash the unit.
