2.4: Mount the IMT Tm-V-4090 Temperature Amplifier Boxes.
The Clean and Dirty PV panels have IMT Tm-V-4090 temperature sensors mounted on them. The
amplifier boxes need to be mounted to the back side of the shelter box with adhesive tape.
1.
Double sided tape is adhered to the back of the measuring amplifier box.
2.
Unpeel the backing and mount the boxes to back right of the shelter box (if looking at it
straight on), as shown in Figure 2-4 below.
3.
Hold the box in place for at least a minute to properly bond the box to the shelter box.
Note: the amplifier boxes should be mounted horizontally with a drip loop on either end
of the cable to avoid water ingress.

2.5: Connect PV panel to the SymphoniePRO logger & iPack.
Wire the PV panel labeled “Logger Power” to the PV terminals on the NRG iPack (Figure 2-5). The cable
can be routed as desired from the panel, down the tower, and into the FRP shelter box.
