- The location of the pressure transducer must always be as close as possible to the pump unit, as close as possible
to the membrane expander, and always after the general retention valve of the pump unit It is essential to install
a general cut-off valve for the pump unit, after the physical location of the pressure transducer.
- If there is more than one pressure transducer in a multiple pump unit (more than one frequency converter with
a pressure transducer connected), the network of interconnected frequency converters will decide automatically,
and with prior reliability tests of the readings of the existing transducers, which is the transducer that will be used
as the general pressure sensor for the whole group.
- If the designated transducer functions erroneously, the set of frequency converters will decide to automatically
change the principal transducer for another that provides more precise readings. The rest of the transducers will
remain on standby ready to be used when required.
c) Installation on a motor:
- Replace the cover of the motor terminal box with the motor support adapter (parts 5 and 11a) provided.
- Break the 3 holes of the metal radiator of the power circuit (part 4) with a screwdriver. The 3 holes are visible
on the inside of the radiator (add the image).
- Screw the metal radiator to the motor support adapter with the help of the 2 screws provided for this purpose
(parts 9 and 11b).
-Tighten the appropriate cable glands to guarantee the declared protection rating (part 10).
- Carry out the electrical connections between the power circuit and the motor using the electric cables supplied
(item 6).
- Connect the power circuit to the cover + control circuit (part 1) using the flat cable.
- Screw the assembly together (part 13).
d) Installation on a wall bracket:
WARNING: For installation on the wall, point 2 of the previous section regarding installation on a motor should
not be carried out, since the 3 holes in the metal radiator would not ensure the adequate protection rating.
- Fix the wall bracket to the wall through the 3 rear holes of the wall bracket (part 7).
- Place the fan at the base of the wall bracket, ensuring upwards airflow (part 8).
- Place the inverter assembly inside the wall bracket, ensuring that the 2 ends of the metal radiator are inside
the wall bracket.
- Fix the inverter to the wall bracket using the 2 side screws drilled into the metal radiator (part 14).
