INSTALLATION
MOUNTING
CONNECTION
1. Controller enclosure must be
mounted in a vertical position.
2. Ensure mounting method does not
compromise enclosure weather
proof rating.
3. Ensure access to main isolator is
not restricted.
4. Ensure cables/conduits entering
the panel have mechanical
protection and that the penetrations
are sealed and do not
compromise the weather proof
rating of the enclosure.
