ttention
: To meet full compliance with FCC Part 15
Subpart B and CENELEC EN 55011, shielded motor
cable should be used between the drive motor output and
the motor . Using shielded cable provides the maximum
filtering to reduce radiated & conductive emissions which
can cause interference with other devices .
CONTROLLER INSTALLATION PROCEDURE
1 . Disconnect electrical power at the main breaker
2 . Drain the system (if applicable)
3 . Install pressure switch or transducer - the pressure switch
or transducer has a 1/4 - 18 National Pipe Thread (NPT)
connection .
4 . Remove the controller cover by removing the lid screws .
Attach the unit to the wall using mounting screws (not
included) .
Wiring Connections
1 . Verify that the power has been shut off at the main
breaker .
2 . Verify that the dedicated branch circuit for the controller is
equipped with the correct rating of circuit breaker .
3 . Remove the controller lid .
