MOUNTING
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.
Note:
Controller must be earthed and all electrical connections must be carried out by a suitably qualified
Electrician. For Single Working Level Float Switch Applications, connect to “Start (Input 3)” terminals only, and NO
bridge wire is required in “Stop (Input 2)” terminals.
