LOOP SUPPLY INSTALLATION
2.1 LOOP SUPPLY MOUNTING
Encapsulated Loop Supply Assemblies are provided with the printed circuit board (PCB) secured to a Power Supply Back Plate Bracket and protected by a Power Supply Board Cover. These units may be mounted directly to a panel or to a 35mm DIN Rail. Board only Loop Supply’s are typically Snap Track mounted (as is the case with the ControlWave EFM). Figure 2 shows a Snap Track Mounted unit while Figure 3 provides dimensions for the “Encapsulated” Loop Supply. Table 3 below provides the type of Loop Supply and mounting arrangement typically associated with the various ControlWave series RTUs.

ControlWave Series | Loop Supply Type | Mounting Notes |
ControlWave MICRO | Encapsulated | Externally |
ControlWave EFM | Snap Track Mounted | Internally |
ControlWave GFC | Snap Track Mounted | Internally |
ControlWave Express | Encapsulated | Externally |
ControlWave ExpressPAC | Snap Track Mounted | Internally |
