Figure 2 Profi-RAM Mounting
Figure 3 Mounting Profi-RAM with 700 Sensor
The Profi-RAM Electronics package is accessed by removing the junction box cover, grabbing the brass pull
knobs, and pulling the package directly out of the enclosure. The module is mounted in the junction box via a
slip-fit over two long stand-offs attached to the bottom of the junction box. The two stand-offs protrude
through two clearance holes in the bottom two PCB’s. To install the electronics package, properly align the
stand-offs with the clearance holes and gently push the Profi-RAM in until the stand-offs make contact with
the top PCB. The Profi-RAM faceplate will be even with the top of the junction box when installed properly.
The Profi-RAM top should be about flush with the top of the enclosure before screwing down the junction box
cover.
