INSTALLATION
1) Mount the device in the desired location (see step 1).
2) Open the lid and route the cable through the strain relief and
connect the wires to the terminal block(s) (see step 2).
3) The device is now ready for configuration.
WARNING! Apply power only after the device is properly wired.
STEP 1: MOUNTING THE DEVICE
1) Select the mounting location (duct, wall, panel).
2) Use the device as a template and mark the screw holes.
3) Mount with appropriate screws (not included).

The pressure tubes are connected to a flow measurement probe (i.e. FloXact), or to the
measurement ports specified by the fan manufacturer. Please see the FloXact installation
guide or the fan manufacturer’s technical specifications for more information.
Figure 1c - Application connections
To configure the output signals (0–10 V or 4–20 mA) for pressure
and flow (velocity or volume), install jumpers on the 3-pin set of
output jumpers for fow and pressure, located on the right side of
the open device (see schematics). Configuration options for the
jumpers are shown in figure 4. (Gray with white dots show that a
jumper is installed.)
