ELECTRICAL CONNECTIONS
All electrical connections are made on terminal block TB1. Set power switch to match the voltage of the
AC line,
115 or 230vac. Connect AC power to terminals 3 and 4. Set the input jumpers JP1 and JP2 to the
positions corresponding to the control input signal type. For a 4 to 20 madc input, place the jumpers to
connect JP1-1 with JP1-2 and JP2-1 with JP2-2. For 0-10vdc input, place jumpers to connect JP1-2 with
JP1-3, and JP2-2 with JP2-3. Connect the appropriate control input signal to terminals 1 and 2. Terminal
2 is the lower potential line.
The IPT has been adjusted at the factory for a 4 to 20 madc or 0 to10 vdc control input signal to produce
a 0 to 80 psig output pressure. No further adjustments are required. However, if adjustment of the output
pressure is desired, see note below.
