The HART-RAM Electronics package consists of three printed circuit assemblies (PCAs). The top two
PCAs (RAM display and HART Bridge) are accessed by removing the junction box cover and using the
brass pull knobs to pull the package directly out of the enclosure. The bottom PCA (terminal board) will
remain attached to the bottom of the junction box via two machine screws allowing the RAM display and
HART Bridge to unseat from the 12-pin plug-in connector and providing access to the terminal board
